Analysis of Heterosis and Heterobeltiosis for Earliness, Yield and Its Contributing Traits in Okra (Abelmoschus esculentus L. Moench)

Thirty-six F1 hybrids were generated from nine lines and four testers through line x tester mating design, these F1’s along with 13 parents 1 commercial check (Punjab-8) evaluated to study the magnitude direction of heterosis for growth earliness over various characters in okra. Heterosis was studied compare traits such as days 50% flowering, picking, plant height, number internodes, branches per plant, fruit length at maturity final maturity, fruits seeds fruit, 100 seed weight, yield plant. Significant found better parent (Heterobeltiosis), mid checks all desirable direction. The present showed that crosses L3 T2 (19.04, 15.41, 8.28), L5 (41.90, 14.55, 7.47), L8 T3 (23.75, 6.48, 8.46) recorded significant positive parent, standard check. Same hybrid exhibited negative highly flowering first picking (-11.65,-12.00, -8.33) (-11.79, -12.12, -15.94) respectively are character These may further be tested locations before release cultivation. High estimates obtained combinations revealed considerable genetic divergence among parental reveals good scope exploitation
