Heterosis Studies in CMS Based and Conventional Hybrids for Yield and Yield Contributing Traits in Cotton (G. hirsutum L.) Over the Environments
International Journal of Current Microbiology and Applied Sciences(2020)
Abstract
The present study comprised of three male sterile CMS lines, three maintainer lines and ten male fertile males (testers/ restorers) with three standard checks in two sets i.e. CMS and conventional thus making 60 F1s (30 CMS and 30 conventional) using Line x Tester mating design. The crosses, CAK 53A x AKH- 07R, CAK 23B x AKH-07R, CAK 23B x DHy-286-1R, CAK 23B x R-2000-23 and SRT-1A x R-2000-26 were found better for seed cotton yield per plant and hold promise for further evaluation and commercial exploitation of heterosis both in CMS and conventional system for high yield.
