is an important fruit crop of economic importance which can be cultivated on marginal lands on a commercial scale, especially in India, where it is indiginious (Arndt et al., 2001). Ziziphus (Rhamnaceae) comprises about 170 species of spiny shrubs and small trees distributed in the warm-temperate and subtropical regions throughout the World (Islam and Simmons, 2006). Ber is a deciduous tree and flowering starts from August to October, its fruit mature from January to March in India (Shukla et al., 2004). Flowering period lasted for about one month long (Mishra et al., 2004). Flowers of Ziziphus are hypanthium (a cup or tube bearing the floral parts above the base of the ovary of the flower) type and inflorescences are cyme or small panicle (Tel-Zur, 2009). The flowers are small and inconspicuous; their most noticeable part is a pale yellow

The study on diversity of pummelo (Citrus grandis Osbeck) was undertaken to assess the variability of collected genotypes from fourteen district of West Bengal in the year of 2016-17. One hundred twenty four genotypes were selected based on assessment of traits provided by the farmers (fruit bearing frequency, maturity, fruit yield) as well as in-situ observation of trees and fruit"s characters with an objective for selecting genotypes from divergent clusters and utilizing them in a hybridization programme is likely to produce desirable segregates in subsequent generations that may lead to desirable improvement in pummelo for quality traits. The analytical works were conducted in the laboratory of Fruits Science of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. The data obtained were analyzed by different method like-Hierarchical cluster analysis, descriptive analysis, Principal Component Analysis and Biplot. The genotypes were grouped based on ten core quantitative characters of fruits into fifty six clusters. It is observed that all the clusters were distant each other and among them cluster 49 was the largest one consisting of 55 pummelo genotypes followed by cluster 43 and cluster 52 with three genotypes. The co-efficient of variation was high (>20) for five measured or quantitative characters like fruit weight, fruit rind thickness, seed weight, acidity, and ascorbic acid. Principal component analysis of ten core quantitative characters of pummelo showed four components with cumulative variance of 69.357 per cent. Highly loaded characters (>0.5), obtained from PCA for quantitative variables in the first two components, were fruit weight, fruit diameter, fruit length, rind thickness, seed number and seed weight. So, considering all the characters it may be concluded that NPC2,

The present experiment was conducted to determine the genetic variability, heritability, genetic advance for yield and yield-related traits in dolichos bean at UAS, Bengaluru, during rabi 2020. The experimental material comprises six bush-type dolichos bean genotypes with two local checks were evaluated for 12 morpho-metric characters in randomized block design with three replications. The mean performance of all the characters analyzed was found significant. The genotype DOLBVAR-4 (52.80cm) recorded the maximum plant height and the minimum recorded for ). The genotype DOLBVAR-2 (60.80g) recorded the highest pods plant -1 , followed by HA 5 (60.60g) and . The green pod yield hectare -1 was maximum for genotype DOLBVAR-2 (3.90 t/ha) followed by HA 5 (3.60 t/ha) and DOLBVAR-3 (2.74 t/ha). In contrast, DOLBVAR-5 (2.00 t/ha) yielded the lowest among all the genotypes. High PCV and GCV were observed for the number of pods plant -1 , pod length (cm), and pod width (cm), indicating the higher magnitude of variability for these traits and consequently more scope for their improvement through selection. High heritability coupled with high genetic advance as percent of mean was recorded for all the characters except for days to 50% flowering, primary branches plant -1 and plant height (cm). These results indicate these characters are under the influence of additive gene action; hence simple selection based on the phenotypic performance of these traits would be more effective.

during 2015-16 with fourteen cultivars of ber to understand and provide a wealth of usable information of ber breeding programme. All the varieties showed wide variation of fruit set (3.9-31.4%), fruit drop (63.085.5%) and retention (14.5-36.9%). Higher percentage of fruit set was noted in Sanur-2 (31.4%), BAU-1 Kul (26.5%), Umran (26.1%), Banarasi Karaka (24.8%). A large percentage of fruit dropped before reaching the maturity stage. However, the heaviest drop was recorded in the variety Banarasi Karaka and minimum in Umran. In all the cultivars the fruit drop was maximum up to 30 days after fruit set, declining later on. In Sanur-2 the fruit set percentage was highest but fruit retention was not up to the mark. Fruit maturity among 14 varieties was 111 to 149 days with a longer period of harvesting (21-37 days) and wide range of yield (15.96 to 46.36 kg/tree). BAU-1 Kul, Gola and Jogia were harvested earlier and Apple Kul, Banarasi Karaka Madhabpur, Mundia, Umran were harvested late. Duration of harvesting was longest in Illaichi. Umran and Topa were higher in fruit yield (46.36 kg and 43.77 kg/plant, respectively).
