Heterosis studies in CMS based and conventional hybrids for fibre quality in cotton (G. hirsutum L.) Over the environment’s

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. For the fibre properties, CAK 23B x R-2000-17-2 and CAK 53A x R-2000-23 for upper half mean length, CAK 53B x R 2000-23 and SRT-1A x R- 2000-23 for fibre strength hold promise for further evaluation and commercial exploitation of heterosis both in CMS and conventional system for high yield and fibre properties.
