Abstract:
The aim of the current research on okra (Abelmoschus esculentus (L.) Moench) was to determine the degree of heterobeltiosis and the level of inbreeding depression for fruit yield and related traits using generation mean analysis. Mean performance of F₁ hybrids exceeded the value of their better parent in desired direction in the cross AOL 16-01 X AOL 18-08 for fruit weight, fruits per plant. In the cross GAO 5 X Red One Long for fruit length, fruit weight, fruits per plant, fruit yield per plant, branches per plant, plant height, internodes on main stem. In the cross AOL 19-10 X AOL 20-03 for fruit length, fruit girth, fruit weight, fruits per plant, fruit yield per plant, internodes on main stem, total soluble solids. In the cross Phule Prajatika X GAO 5 for plant height, internodes on main stem, length of internode, while for days to initiation of flowering, none of the F₁ per se performance was lower than its better parent. Mean performance of backcross progenies was not consistent in different crosses for different traits. These generation could be further utilized for selecting higher fruit yield per plant. For selection of any traits the generation which is superior to the parents can be advanced for future breeding programme.
