Abstract:
The present investigation was carried out with the aim to assess the genetic diversity among the parents and their off-springs. The study was conducted during Zaid, 2020 (Y₁) and Zaid, 2021 (Y₂). The present investigated shows that the analysis of variance revealed that mean squares due to genotypes were found significant for all the traits in the both seasons (Y₁, Y₂) and over seasons (Pooled). The moderate phenotypic as well as genotypic coefficients of variation observed in case of fruit yield per plant, number of fruits per plant, non-reducing sugars and node number to first male flower appearance during both seasons (Y₁, Y₂) and over seasons (Pooled), vine length, flesh thickness, internodal length, number of primary branches per plant, node number to first female flower appearance, β-carotene, reducing sugar and average fruit weight during both seasons (Y₁ and Y₂).The estimates of high heritability coupled with high genetic advance as per cent of mean were observed for fruit yield per plant, non-reducing sugars, number of fruits per plant, node number to first male flower appearance and flesh thickness during Y₁ and Y₂ while, number of primary branches per plant, β-carotene and reducing sugars during Y₁. High heritability coupled with moderate genetic advance was observed for total soluble solids during Y₁ and Y₂. Moderate heritability coupled with high genetic advance were observed for non-reducing sugars during over seasons (pooled) which indicating the additive gene action for these traits and the phenotypic selection could be relied upon.
