Abstract:
Okra, being an often cross-pollinated crop, responds well to heterosis breeding. Exploitation of heterosis is primarily dependent on the screening and selection of available germplasm that could be produced by better combinations of important agronomic characters. An experiment was carried out in kharif 2020 to estimate standard heterosis for yield and its contributing traits using 24 hybrids developed through line x tester design were evaluated at three different locations at Navsari Agricultural University, Navsari (Gujarat) with commercial check ‘GJOH 4’. Appreciable heterosis was found over commercial check for all the traits studied in desirable direction. Among the 24 hybrids, NOL-17-6 × Arka Anamika gave consistency in performance with respect to pod yield across all environments (E1, E2 and E3) followed AOL-12-59 × Kashi Kranti (E1 and E2) and NOL-18-10 × Kashi Kranti (E2 and E3). An overall view of all the top yielding crosses with respect to pod yield contributing traits revealed that the higher pod yield was mainly due to number of pods plant^-1.
