Heterosis studies by using L x T design for yield and yield contributing traits in okra (Abelmoschus esculentus (L.) Moench)

Abstract

To determine superior hybrids, the current investigation in okra intended to examine and estimate the heterosis for various yield and yield-contributing traits. The Lx T mating design was used to create 33 cross combinations from 11 female lines and 3 testers, and enough F1 seeds were produced in summer 2021. The F1's were planted to observe the performance of various crosses with three checks in kharif 2021. At the Breeder Seed Production Unit VNMKV Parbhani, the experiment was carried out. The best crosses for upcoming studies on the creation of hybrids have been found to be these crosses. Although the level of heterosis varied between the characters, each character displayed significant heterosis. EC-305653 x IC-45800, EC-5612 x Parbhani Kranti, EC-305741 x IC-45800, EC-305652 x Parbhani Kranti, and EC-305664 x IC-45800 were the top five crosses. Nine of the 33 crosses tested outperformed the others in terms of high heterotic and desirable specific combining ability effect, as well as high per se performance for fruit yield. These hybrid okra varieties could be produced by further heterosis breeding using these crosses.
