Exploitation of heterosis in rice (Oryza sativa L.) using CMS system under temperate conditions
Electronic Journal of Plant Breeding
The present study was conducted to evaluate 36 cross combinations developed by crossing 2 CMS lines with 18 testers in line xtester mating design to identify effective restores and maintainers from elite lines and work out best heterotic combinations interms of yield and yield components. Assessment of standard heterosis based on standard checks (SR-1 and Jhelum) ofeffectively restored cross combinations showed that there was significant heterosis for all the traits except number of filleddoaj:f7366ca440a845f1a552783305a437ef fatcat:bk7c2d72hng5tezcijdek3dc3a
