Abstract:

Study of genetic parameters in F5 segregating population developed from the cross EC 771612 × LA 2657 during summer 2017 for fruit yield and its attributing traits and traits related to WUE was carried out in augmented design. Analysis of variance indicates the presence of significant variability for all the characters among F5 segregants which indicates the existence of sufficient variability. Therefore the population was subjected for determination of genetic parameters and correlation. High GCV and PCV coupled with narrow difference between PCV and GCV were found for fruits per plant, plant height, clusters per plant and fruit yield per plant indicating less environmental influence on expression of these characters therefore individual plant selection can be followed for improvement of these characters. High heritability coupled with high genetic advancement as a per cent of mean was observed for fruits per plant, plant height, and clusters per plant and fruit yield indicating the involvement of additive gene action for expression of these traits in crosses studied. Characters like fruits per plant, plant height; fruits per clusters and clusters per plant have shown the presence positive significant association with fruit yield among F5 segregants implying that fruit yield per plant could be improved up on improving some of the traits like fruits per plant, plant height, fruits per clusters and clusters per plant.
