Exploitation of heterosis for yield and yield attributes in okra [Abelmoschus esculentus (L.) Moench]
Author(s): Sreeparna Chowdhury and Sanjeev Kumar
Abstract: Seven genotypes and their 21 F1 crosses obtained from half diallel mating design were investigated to estimate the magnitude of heterosis for yield and its parameters. The extent of heterosis ranged for all the characters under study. Desirable heterosis for days to 1st flowering was observed in Annika X Rajini over both mid parent and better parent while the cross EC359637 X Arka Anamika significant desirable heterosis over standard check. For average fruit weight, the maximum magnitude of heterosis was obtained in cross EC359637 X Arka Anamika over average parent, Annika X IC014026 over better parent and Annika X EC359637 over better parent. Maximum desirable heterosis for yield per plant was observed in EC359637 X IC014026 over mid parent, better parent and standard check followed EC359637 X IC013664 and EC359637 X EC305768. Higher magnitude of heterosis observed in crosses revealed presence of significant genetic diversity among the genotypes.
