Genetic variability and correlation studies for productivity traits in cucumber (Cucumis sativus L.)

Thirty cucumber cultivars were evaluated for growth and yield traits at College of Horticulture, Sirsi Karnataka. Results revealed that significant genetic variability present among genotypes for various traits, a high range of variation; high GCV and high heritability coupled with high genetic advance was recorded for node at first female flower, number of male flower, number of female flower, fruit weight, flesh thickness, fruit length and fruit width. It reveals that broad genetic base, less environmental influence and these traits are under control of additive genes. Further correlation analysis showed that number of female flower, fruit diameter and fruit number / vine had highly significant association with fruit yield. These traits can be used for parental selection in the improvement of local cultivars.
