Not AvailableSequence-related amplified polymorphism (SRAP) was used to assess the genetic diversity of 114 pomegranate accessions sourced from all over the world and maintained in the field gene bank at ICAR-Indian Institute of Horticultural Research, Hesaraghatta, Bangalore. Totally 10 SRAP combinations were used for the study. Genetic parameters such as effective alleles (Ne), Nei genetic diversity (H), Shannon index (I), and polymorphic information content (PIC) were calculated based on molecular data. The number of alleles per locus ranged from 1.66 to 4.00 with an average of 2.03. The average polymorphic information content (PIC) value was 0.24. The expected heterozygosity varied from 0.215 to 0.445 with an average of 0.306. Cluster analysis was performed using R software. All the 114 accessions were grouped into four major clusters. There was no clear grouping based on origin. The analysis of molecular variance (AMOVA) indicated insignificant genetic variation (p=0.31) between pomegranate accessions from different geographical locations. Overall genetic variation among the population groups was low, while 99% of variation was due to within group differences. These results confirmed that SRAP markers could be a powerful and an effective marker system for determining the genetic diversity and population genetic structure of the pomegranate.ICAR-IIH

The results showed that the fruits with highest weight (197.55 g), length (6.64 cm), total aril weight (113.63 g), percentage of aril weight (62.11 %), 100 aril weight (27.18 g), juice weight (101.94 g) and percentage (51.19 %) accompanied with highest anthocyanin content (6.647 mg 100g-1) were obtained with application of CCC @ 1000 ppm plant-1 in combination with Uracil @ 25 ppm. Highest fruit diameter (6.90 cm), TSS content (19.96 0B), TSS to acid ratio (46.68) and less titrable acidity (0.41 %) were apparent with foliar spray of Cycocel @ 1500 ppm plant-1, while its application @ 1000 ppm has resulted in highest fruit volume (162.70 ml).Not Availabl

Total 151 pomegranate genotypes along with their hybrid parents (Bhagwa, DF, Nana) combinely 154 used for morphological characterization. Total 13 morphological parameters were used for characterization and Analysis of Variance, mean comparison and simple correlations were analysed. Significance differences (P<0.05) were found among all the genotypes of pomegranate. Highest critical differences at 5% were 13.21 (Fruit weight), 11.98 (Aril %), 2.552Thorn [No/Shoot length (m)] recorded and lowest in leaf blade width 0.143, 0.145 in leaf blade length, 0.456 in fruit length and 0.48 in seed hardiness respectively. Plant growth parameters, leaf parameters and fruit parameters are significantly correlated to each other. Fruit weight and seed hardiness was negatively correlated to each other (r= -0.42). Those fruit have larger size and weight have less seed hardiness. Fruit characteristics are negatively correlated with leaf characteristics (r= - 0.22).The largest the leaf size smallest the fruit size.Not Availabl

Not AvailableTo realize the productivity potential of pomegranate cv. Bhagwa, studies were conducted on the effects of chemicals Nitrobenzene (1.0, 1.5 and 2.0 ml plant-1), Cycocel (500, 1000 and 1500 ppm plant-1) and Uracil (25 and 50 ppm plant-1) on flowering behavior and fruit yield during the years 2016-17. Highest number of hermaphrodite flowers (264.66), fruit yield (27.10 kg tree-1 and 18.86 t ha-1) and fruit number tree-1 (154) were realized with application of uracil @ 50 ppm. However, the uracil treatment did not influence significantly the number of male and intermediate flowers. Application of Cycocel @ 1000 ppm in combination with Uracil @ 25 ppm plant-1 has recorded highest fruit weight (197.55g). At flowering stage, the gas exchange parameters like the photosynthetic rate (16.48 μmol m-2 s-1) was higher in plants treated with Uracil @ 50 ppm while transpiration rate was higher (7.72 mmol m-2 s-1) with uracil @ 25 ppm. Higher stomatal conductance (0.44 mol m-2 s-1) was recorded under nitrobenzene @ 1.5ml plant-1 treatment. During fruit set stage, photosynthetic rate was high (12.55 μmol m-2 s-1) in plants treated with nitrobenzene @ 1.5 ml plant-1 whereas, transpiration rate (6.19 mmol m-2 s-1) and stomatal conductance (0.18 mol m-2 s-1) were higher in plants treated with Cycocel @ 1000 ppm + Uracil @ 25 ppm plant-1. Thus Uracil @ 50 ppm alone seems to be effective in enhancing fruit yield and the beneficial effects were associated following increases in gas exchange parameters and bisexual flowers.Not Availabl

TDZ-induced direct shoot organogenesis and somatic embryogenesis on cotyledonary node explants of lentil (Lens culinaris Medik.)

An efficient and simple procedure for inducing high frequency direct shoot organogenesis and somatic embryogenesis in lentil from cotyledonary node explants (without both the cotyledons) in response to TDZ alone is reported. TDZ at concentration lower than 2.0 μM induced shoot organogenesis whereas at higher concentration (2.5–15 μM) it caused a shift in regeneration from shoot organogenesis to somatic embryogenesis. The cotyledonary node and seedling cultures developed only shoots even at high concentrations of BAP and TDZ, respectively. TDZ at 0.5 and 5.0 μM was found to be optimal for inducing an average of 4–5 shoots per cotyledonary node in 93 % of the cultures and 55 somatic embryos in 68 % of the cultures, respectively. The somatic embryos were germinated when transferred to lower TDZ concentration (0.5–1.0 μM). The shoots were rooted on MS basal medium containing 2.5 μM IBA. The plantlets were obtained within 8 weeks from initiation of culture and were morphologically similar to seed-raised plants. The possible role of stress in thidiazuron induced somatic embryogenesis is discussed
