Genetic studies in F2 generation of bhendi [Abelmoschus esculentus (L.) Moench]

Abstract

Genetic studies involving F2 segregants of bhendi arising out of two crosses viz., SKY/DR/RS/107 X Tiruchi Local and IC69257 X 770 along with their four parents and a check (Arka Anamika) was performed using twelve biometric traits recorded from randomly selected plants. Both PCV and GCV were of high magnitude for the number of primary branches at final harvest, internodal length, fruit yield per plant and the number of fruits per plant in both the crosses, indicating the importance of these traits in exercising selection. The traits, internodal length, plant height at final harvest, the number of primary branches at final harvest, the number of fruits per plant and fruit yield per plant had registered high magnitude of heritability coupled with high genetic advance as percentage of mean in both the crosses, revealing the preponderance of additive genes in control of these traits.
