Abstract

The present investigation was carried out with a vision to study the combining ability for important productivityand fibre quality traits of cotton. Fifty five hybrids generated through Griffing’s half diallel method were evaluated alongwith eleven parents and two checks RAHH 455 and SHH 818 in 2017-18 at the Main Agricultural Research Station,Raichur. SCS-PL-03 expressed significant gca effects and could be used to exploit varietal development with respect toseed cotton yield. SCS-PL-12 was identified as parent having significant gca effects with respect to UHML. The performanceof the hybrids in the present study could be expected on the basis of the average performance of the parental inbred lines.
