Abstract: High temperature
stress has emerged as a widely occurring problem in sugarcane growing tracts,
in general and in subtropical India, in particular, affecting growth and
development of sugarcane in early pheno-phases of
establishment and shoot formation. Seventy one sugarcane varieties from
Peninsular, North-west, North-central and North-eastern sugarcane zones of
the country were screened for their tolerance to high temperature stress. The
tolerance has been assessed on the basis of drying of leaf-tips and margins
(leaf injury) and rolling of leaves. Some varieties have the potential to
escape high temperature stress and some other varieties were able to tolerate
high temperature induced stress. Some of the varieties suffered from
excessive leaf injury and leaf rolling, indicating thereby their inability to
tolerate high temperature stress. The leaf rolling during formative phase of
the crop showed qualitative impact on the tonnage of the crop at harvest.
These varieties may further be explored for their use in breeding programmes.

Abstract: The present
experiment was carried out with 126 diverse genotypes of forage sorghum
including two checks (SSG-59-3 and SMU-1) in Randomized Block Design with
three replications during kharif,
2013. Observations were recorded for 24 characters. GCV ranged from 7.10 to
37.19 % with 6.5 SD and was high (> “mean + SD” i.e. >20.92) for
stem juiciness (37.19). The magnitude of PCV ranged from 10.23 to 50.57 with
9.40 SD and was high ( mean + SD, i.e.
>34.2) for stem juiciness (50.57). Heritability (h2) was high ( mean +SD, i.e. >54.58) for number of leaves
per plant (74.05) and medium (in between mean+ SD, >15.32 to
<54.58) for stem juiciness (54.09). The expected genetic gain was
high (“mean +SD”, i.e. >29.22) for stem juiciness (54.35). Most
selection responsive character was stem juiciness as it was having higher
GCV, PCV and genetic gain and moderate heritability (h2). On the
basis of heritability and genetic gain, selection criteria based on number of
leaves per plant, leaf length leaf breadth, stem juiciness, protein per cent
may be useful for further developing good quality and high yielding forage
sorghum cultivars. Keywords: Forage sorghum,

Abstract: Impact of the
society on oilseed production can be judged by the area allotted under
oilseed crops and per acre yield obtained by members and no-members and yield
obtained by members (3.56q/acre) was relatively higher than non-members
(3.05q/acre) since, encouragement, guidelines and technical assistance
provided by RRU has made good impact on the production. The study has
provided that, 91.91 per cent of non members were willing to become members
of society, Only 8.89 per cent of them were not willing to become members of
OGCS because they had personal relationship with traders and commission
agents. Hence the federation should take note on the suggestion made by
members to improve its service to the oilseed and the ongoing price policy
should be directed towards assuring appropriate remunerative prices to
oilseed growers in the state in general and study area in particular. Key words: OGCS, RRU, CAG,

heritability was associated with high genetic advance for number of secondary
roots, fresh shoot weight, number of squares per plant, moisture content of
squares and dry leaf, shoot and root weight. This shows the variation was due
to additive gene effects. The germplasm lines viz.,
CPD-424, CPD-2007-4, CPD-443, RDT-17 and HBS-123 recorded 25% higher
secondary root length (30.8 to 38.0 cm) than ARBH 813 (24.26 cm) and their
primary root length (19.0 to 29.5cm), number of secondary roots (17.0 to
34.5) and root weight (11.5 to 18.0 g/plant) were comparable to checks. The
genotypes viz, AKA-081, EC560327,
GISV-272, JBWR-23, HBS-102 and RDT-17 recorded 40 percent more number of
secondary roots (34.5 to 41.0) than superior check, DS 28 (24.5). They

Abstract: The bael (Aegle marmelos Correa) is an important indigenous arid zone
fruitbelonging to family rutaceae
often termed as underutilized minor fruit. The population of F. solani infested soil could be minimized by treating
the soil with T. harzianum, T. virens and T. viride.
Trichoderma harzianum
and T. virens grew very fast. Beside T. harzianum parasitized over F. solani,
resulted into lyses of its hyphae. The antagonistic
activity of T. viride happened due to its
yellow pigments secreted in the rhizosphere. The
yellow coloured metabolite was toxic and killed the
hyphae of F. solani.
Thereafter, T. viride grow over the space
cleared by its metabolite on the basis of the results of the present
experiment. Application of T. viride and T.
virens as preventive measures and that of T.
harzianum as curative one may be suggested. Keywords: Aegle marmelos Correa, Root rot, F. solani, Trichodermaharzianum, T.

Abstract: This experiment
was conducted to find out the effect of gamma radiation and packaging
material on shelf life and post harvest quality of mango fruits cv. Dashehari. During both the years mango fruits were
irradiated with 0.0 Gy (G1), 100 Gy (G2), 200 Gy (G3),
300 Gy (G4) and 1 kGy
(G5) gamma radiation and packed in different packaging material
viz. bamboo basket (P1), plastic basket (P2),
CFBB (P3) and perforated polythene bags (P4) and stored
under ambient conditions (24.5-330C with 61-84.5% RH). The data on
physiological loss in weight, retention/shelf life of fruits and different
chemical composition viz. TSS, acidity, ascorbic acid (vitamin-C), reducing, non-reducing and total sugar was recorded at 4, 8
and 12 DAS. The results of this study showed that mango fruits treated with
200 Gy gamma radiation and
packed in corrugated fibre board boxes
significantly influenced the physico-chemical
properties with minimal changes in chemical content during storage. Lowest
physiological loss in weight (5.23%, 7.27% and 10.27%) was observed with G3P4
interaction after 4, 8 and 12 days of storage, while, the shelf life of
fruits could be extended upto 8 days with 100%

Abstract: The present
experiment was conducted at department of genetics and plant breeding,
Allahabad school of agriculture, Sam Higginbottom
Institute of Agriculture Technology and Sciences, Deemed University. Analysis
of variance showed highly significant differences among 20 genotypes for
grain yield and its compent characters. In the
present investigation, relative higher magnitude for the genotypic
correlation than the phenotypic correlation was noted there by indicating
strong inherent association among various characters. Correlation coefficient
analysis indicated that ear girth, ear length, harvest index, biological
yield, 100 grain weight and number of grains per row showed positive
significant correlation with yield. Hence indirect selection for these traits
could be helpful in the improvement of grain yield. Path analysis showed
that, days to 50 per cent tasseling, plant height,
ear girth, ear length, number of grains per row, biological yield, harvest
index, ear height, days to 50 per cent silking and
100 grain weight had very strong relationship with grain yield per plant. An
increase in any one of these or all of there
quantitative characters would bring simultaneous increase in yield. Direct
selection for these traits can help improve maize grain yield per unit area. Key words: Genotypic,

Abstract:Buckwheat (Fagopyrum esculentum) is a
moisture loving, cool climate, annual grain with much potential for use in
sustainable tropical cropping systems. It is a reliable cover crop in summer
to fit a small slot of warm season for establishment. It establishes quickly
and suppresses summer weeds. Buckwheat plants grow quickly and produce seeds
in about 6 weeks and ripening at 10 to 11 weeks. They grow 30 to 50 inches
(75 to 125 cm) tall. It is an erect, glabrous annual herb,
leaves are ovate-shaped, flowering in July-September, in Sikkim. These plants
were found to be affected by false root knot nematode which induced the galls
on root of buckwheat. The symptomatic and microscopic examination revealed
that the nematode was Nacobbus sp. Perusal

Abstract: Considerable
increase in crop production is achieved due to introduction of irrigation and
adoption of new crop production technologies and crop varieties in India. In
spite of its beneficial effects of irrigation, soil salinity and waterlogging are unavoidable processes in vertisols in semi-arid regions because of their inherent
poor drainage property coupled with high potential evapo-transpiration
rates. Vast area has been already affected due to these twin problems and
more land is likely to go out of cultivation if non-judicious use of water is
continued. Re-habilitation of these vast stretches of saline/waterlogged
lands has become vital, as there is an obligation to provide food to the
ever-growing population. Subsurface drainage system was installed in the
farmer’s field near Virupapur village, in Karnataka
during 1998 in an area of 62 ha and its performance was studied in terms of
changes in soil salinity, water table, crop yield and cropping intensity.
Considerable reduction in soil salinity, lowering of water table, and
increase in paddy yield and improvement in cropping intensity was recorded in
the subsurface drained area. Nitrogen loss through subsurface drainage system
was estimated and it was in the range of 2 to 7 per cent of the recommended
dose of nitrogen for paddy(i.e., 150 kg/ha)
during different crop season. Partial blocking of the drainage system by the
farmer’s was also observed resulting in increase in soil salinity in the
lower profiles of the soil. Key words: Soil salinity, Waterlogging, Subsurface drainage, Land reclamation and

Abstract: Pomegranate (Punica granatum L.)
is one of important horticultural plant in India with about several genotypes
cultivated in several regions of country. Molecular markers including RAPD,
and SSR were used to evaluate genetic diversity of twenty four pomegranate
cultivars. Genetic parameters consisted of effective alleles (Ne), Nei genetic diversity (H), and polymorphic information
content (PIC) was calculated based on molecular data. RAPD markers with their
dominant nature showed the highest value of genetic parameters aforementioned
with PIC value among all markers. Combined data of RAPD markers showed higher
genetic diversity than SSR markers. UPGMA tree obtained from combined
molecular data (total 1017 amplicons) discriminated
pomegranate genotypes in two major groups. Principle Component Analysis (PCA)
based on the first two components confirmed clustering. The homonymous,
synonymous and/or mislabelled genotypes were
identified using random decamer DNA markers. The
matrix analysis showing calculated genetic similarity values indicated
significant similarity (p= 0.94) between pomegranate genotypes in different
localities. Only 2% of overall genetic variation was due to among locality
groups differencewhile 98% of variation was due to
within group differences. Keywords: Combined

Abstract: Combining ability
of the parents was estimated by using line x tester analysis to determine the
ability of parents to combine their favourable
alleles/genes during the process of hybridization and transfer those to their
progenies. Two types of combining abilities viz., general combining
ability (GCA) which is due to additive genes whereas specific combining
ability (SCA) is due to dominant and epistatic gene
effects were estimated. Twenty seven parents (22 lines and five testers)
along with their 110 F1 hybrids were studied in lattice square
design (LSD) with two replications during 2014-15 at ARS Hebballi,
University of Agricultural Sciences, Dharwad.
The important yield contributing traits viz., number of bolls per
plant, boll weight (g), seed cotton yield (q ha-1), ginning
outturn percentage and seed index (g) were studied. The results indicatedthat GCA variances due to lines and testers and
SCA variances due to lines x testers interaction
were significant for all the characters studied. However, the magnitude of
GCA from lines (females) and testers (pollinators) were lesser than the SCA
indicating pre dominance of non-additive genes in the expression of all the
traits except boll weight. Nonetheless, among the lines, DHS 10-4, MCU 8 and
TCH 1457 whereas in testers, DHS T2 and DHS T3 by manifesting maximum GCA
effects were regarded as the best general combiners for almost all the traits
suggesting the presence of more additive genes in these parents, hence may
serve as potential parents to be considered for hybridization and selection
programmes to improve the characters studied. Among the F1 hybrids,DHS 10-4 x DHST1, TCH 1457 x DHS T3 and IC 3584 x
DHS T3 were found as the best specific combiners for seed cotton yield.
Therefore, these hybrids may be preferred for hybrid crop development. Key Words: Combining ability,

Abstract: In an experiment
conducted to find the effect of nutrient doses on growth and yield of glory
lily during 2012-13 at Antravalli, Kumta (Uttara Kannada,
Karnataka),with six treatments replicated four times,15t Farm Yard Manure
(FYM) + 150:75:120 kg NPK / ha registered significantly highest vine length
(181.80 cm), number of branches (9.40), stem girth (6.97 mm), fresh seed
yield (32.03 q/ha) and dry seed yield (6.57 q/ha). Fresh and dry seed yields
in this treatment were statistically on par with 15t FYM + 125:70:100 kg NPK
/ ha. Significantly highest number of pods (17.0) / plant and pod length
(7.11 cm) were recorded in 15t FYM + 100:50:75 kg NPK / ha and 15t FYM +
125:70:100 kg NPK / ha, respectively. The highest tuber yield per ha (26.61q)
was recorded in 15t FYM + 100:50:75 kg NPK / ha. KEY WORDS:Agnishikha, Gloriosa lily, Glory lily, Nutrient doses |

Abstract: A field experiment
was conducted during the kharif season
of 2013-2014 in Vertisols of rainfed
areas of central India to study the effect of application of graded doses of
potassium (15, 30 and 45 kg K2O ha-1) on growth and
yield of pearlmillet (Pennisetum
glaucum (L.) R. Br.). Five treatments of different
levels of potassium were tested in Vertisols
possessing available potassium level up to 340.3 kg ha-1.
Application of 60:30:00 kg NPK ha-1+45 kg K2O ha-1
recorded the maximum plant height, number of functional leaves, leaf area,
girth of main stem and dry matter accumulation with highest values of yield
attributes viz., number of effective tillers plant-1, number of earhead plant-1, mean length of earhead, circumference of earhead,
weight of earhead g plant-1, weight of
grains g plant-1 and test weight. Similarly, it enhanced the pealmillet grain and stover
yield to an extent of 1690 and 3591 kg ha-1. KEY WORDS: Grain yield,

Abstract: Fruit ripening is
a complex phenomenon with drastic changes in chemical composition, which
enhance an important quality attributes such as flavour,
softness, sweetness and color. These changes are very coordinated and involve
many biochemical steps, which are upon a stringent and integrated control
played by plant hormones and gene expression, including epigenetic mechanism.
The expression of specific genes is essential to normal ripening and the
synthesis of enzymes involved in the autocatalytic ethylene burst during
climacteric fruit ripening. However, several other metabolic pathway are
dependent on the modulation by gene expression, and some genes of enzymes
putatively controlling the most important physiological changes associated to
fruit ripening have been pointed. Based on the studies on tomatoes, there is
already some understanding about the genes involved in the most important
physiological changes, such as the accumulation of soluble sugars, cell wall
disassembly, and synthesis of pigments during fruit ripening. In this way,
the identification of genes induced during ripening could provide important
clues about the activation of biochemical steps and its relationship to fruit
quality. Keywords:

Abstract: A field experiment
was carried out during Rabi and Kharif
season at ZARS, UAS, GKVK, Bangalore under sick plot
soil condition. Among the 15 treatments employed in management of dry root
rot(DRR) during the Rabi seasonseed
treatment with tebuconazole (2g kg-1 of
seed) recorded significantly lowest dry root rot incidence of 7.12% with highest
yield of754.74 kg ha-1, followed by seed treatment with tebuconazole (2g kg-1) + carbendazim
(1g kg-1)recorded 14.87 % disease incidence with a yield of 721.05
kg ha-1compared to control which recorded 42.18 % diseases
incidence with yield of 309.86 kg ha-1. During Kharif season also seed treatment with tebuconazole (2g kg-1 of seed) recorded lowest
dry root rot incidence of 10.28 % with highest yield of 697.36 kg ha-1,
followed by seed treatment with tebuconazole (2g kg-1)
+ carbendazim (1g kg-1) recorded 16.44 %
disease incidence with yield of 637.86 kg ha-1 compared to control
which recorded highest disease incidence of 45.64 % with yield of 259.55 kg
ha-1. Mean data of Rabi and Kharif
seasons indicated that seed treatment with tebuconazole
(2g kg-1 of seed) recorded least disease incidence (8.70 %) with
highest yield of 726.05 kg ha-1 and C: B ratio (1:2.37), followed
by seed treatment with tebuconazole (2g kg-1)
+ carbendazim (1g kg-1) recorded 15.66 %
diseases incidence with yield of 679.45 kg ha-1 and C: B ratio of
1:2.20 compared to control which recorded 43.91 % diseases incidence with
yield of 284.70 kg ha-1 and C: B ratio of 1:0.95. Key
