Abstract

Genetic Variability, heritability and genetic advance for different characters were studied in 20 cucumber genotypes. The study indicated existence of considerable amount of genetic variability for all the traits except cavity of fruit at edible stage. The maximum phenotypic and genotypic coefficient (PCV and GCV) was observed for number of days to first female flower anthesis. High estimates of heritability (broad sense,) genotypic coefficient of variation (GCV) and genetic advance were observed for some traits.
