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.
