Abstract:
The present investigation in okra intended to examine and estimate the heterosis for fruit yield and its contributing characters. L × T mating design was used to create 48 cross combinations from 6 lines and 8 testers and enough F₁ seeds were produced in summer 2022. The F₁'s along with their 14 parents and one standard check (GJOH 4) were evaluated during kharif 2022. The heterobeltiosis for fruit yield per plant varied from -28.22% (GAO 8 × AOL 20-05) to 19.40% (AOL 18-06 × AOL 19-12) for fruit yield per plant while for useful heterosis values varied from -24.87% (Phule Prajatika × AOL 21-14) to 90.81% (GAO 5 × AOL 20-03). GAO 5 × AOL 20-03, GAO 8 × AOL 20-03 and AOL 21-10 × AOL 20-03 were the top three crosses which had high per se performance as well as significant and higher estimates of standard heterosis for fruit yield per plant and its contributing traits.
