Abstract:

The Genotypes Annu 50 (240.g) and 10.45 t ha-1) was recorded highest mean performance for fruit yield plant-1 and no. of fruit plant-1). The genotypic coefficient variance value were categorized as low (0-10%), moderate (10-20%) and high (20% and above). In the present study the heritability estimates in broad sense were classified into 3 groups such as high (>75%), moderate (60% - 75%), low (<60%). The genetic advance estimates were found to be high for Plant height, and Yield plant-1 (g). The high genetic advance as percent of mean was recorded for Plant height, Number of branches per plant, Fruiting node, Fruit length (cm), Fruit width (cm) and Fruit weight (g). Genotypic and phenotypic coefficient analysis revealed that fruit yield per plant showed positive significant association with Plant height, Length of internodes (cm), Days taken to first picking, Number of nodes to first flowering and Fruit yield (t ha-1). Genotypic and phenotypic that highest direct positive effect on fruit yield per plant (g) was exhibited by Number of branches per plant, Length of internodes (cm) at both genotypic and phenotypic and Days taken to 50% flowering, Number of fruit per plant, Days taken to first picking, Number of nodes to first flowering and Fruiting node at phenotypic and Fruit length (cm), Fruit weight (g), Fruit yield (t ha-1) at both genotypic and phenotypic level. Clustering pattern indicated that cluster I is largest cluster comprising 18 out of twenty-two genotype. On the other hand cluster II, comprised 1 genotype, cluster III, IV, V cluster comprised 1 genotype. The inter cluster distance was maximum between cluster IV and V (435.065) Cluster I, II, III, IV, V was characterized by high mean value for plant height (cm) and low mean values for Fruit width (cm). The highest contribution in manifestation of genetic divergence was exhibited by Number of fruits per plant,. Days taken to first flowering, Fruiting node, Fruit length (cm), Fruit width (cm), Fruit weight (g) and Yield per plant(g)and Yield per plants(t ha-1).
