Extent and magnitude of heterosis for fruit yield and it’s contributing traits in okra [Abelmoschus esculentus (L.) Moench]

Abstract

The investigation comprised of a half-diallel set of eight parents including standard check GAO 5 and their 28 crosses in okra. The experiment was laid out in randomized block design with three replications at Main Vegetable Research Station, Anand Agricultural University, Anand during kharif- 2014. The estimates of heterosis, cross combinations GO 2 x GPOK 123, AOL 10-22 x GPOK 578 and GAO 5 x GO 2 were found the most promising for fruit yield and other desirable traits; hence, could be evaluated further to exploit the heterosis or utilized in future breeding programme to obtain desirable segregants for the development of superior genotypes
