GENETIC ANALYSIS OF YIELD AND YIELD CONTRIBUTING TRAITS IN OKRA (Abelmoschus esculentus L. Moench)
The generation mean analysis involving six generations (P1, P2, F1, F2, B1 and B2) was carried out to study the nature and magnitude of gene effects for eleven characters in okra. The study was conducted at Departmental Farm of Department of Agricultural Botany, College of Agriculture, Dr. B.S.K.K.V., Dapoli Kharif-12. The Mather’s individual scaling tests and Cavalli’s joint scaling tests were used to detect the presence or absence of the epistatic interactions. The results obtained showed the importance of additive, dominant and all three types of epistatic interactions for most of the crosses and characters viz., nodal position for first flowering, days to first flowering, days to first picking, plant height, number of branches per plant fruit length, fruit weight, number of fruiting nodes per plant, number of fruits per plant, internodal length and yield per plant. For majority of crosses duplicate epistasis was observed while for fruit weight complementary epistasis was observed.
