Genetic analysis of yield and its components in okra (Abelmoschus esculentus (L) Moench)

Abstract

Combining ability variance and effect of yield and its components in okra (Abelmoschus esculentus (L) Moench) were studied through half diallel analysis of 28 F1 hybrids derived by crossing nearly homozygous germplasm lines namely PK, VRO35, VRO54, 7218, VO-2, KS-404, 7109 during Kharif 2010 (July to October) at vegetable research form C.S.A.U.A & T Kalyanpur, Kanpur India the role of non-additive gene action for all the characters in both the generations except for nodes per plant, width of fruit, number of fruits per plant and yield per plant and role of additive gene action for all the a characters is both generation. The mean performance and significant gca effect revealed that the parents (KS -404, 7218, VRO-54 and BO-2) were good combiner for days to flowering and KS-40 4 & PK are good general combiner for yield/Plant. The crosses significant and positive and desirable SCA ca effect for yield per plant was founded 12 cross combination F1 generation and 11 in F2 generation. There were PK x KS- 404, PK x P-7, KS- 404 x BO-2 and 7218 x VRO -54 should utilized in recombination breeding with single plant selection in the passing generations to capitalized additive gene action to develop high yielding lines or verities in Okra.
