The experiment was carried out to assess the genetic variability, character association, and path analysis in fifteen gynoecious parthenocarpic hybrids/lines of cucumber under polyhouse (fifty percent shade/naturally ventilated) conditions.
The genotypic and phenotypic coefficient of variations were highest for the nodal position of the first female flower (48.44 and 51.04), number of fruits (40.99 and 41.24), fruit weight(26.40 and 27.39), and fruit yield per plant(38.22 and 38.93). High heritability coupled with high genetic advance as a percent mean was observed for most of the characters, indicating that these characters are controlled by additive gene action.
The fruit yield per plant showed a significant positive correlation with the number of fruits per plant (0.819 and 0.825), plant height (0.302 and 0.303) and significant negative correlation with days to fifty percent flowering (-0.682 and -0.707), nodal position of first female flower (-0.652 and -0.716) and days to first female flower (-0.373 and -0.379) both at phenotypic and genotypic. Maximum positive direct effects towards fruit yield per plant was contributed by days to fifty percent flowering, number of fruits per plant, and fruit weight were the most influencing factors. The hybrids, namely Vally Star, Multi Star, Silyon, and Pune collection were the best with respect to earliness, superior quality, and maximum yield.
