Abstract

The present investigation was carried out to study the combining ability for yield and yield related traits. Among the parents KH-111 found best general combiner for seed cotton yield per plant and component characters. Two hybrids, KH-111 x RAH-101 and NA-1325 x G. Cot-16 identified as best cross combinations based on sca effects for seed cotton yield per plant , yield contributing components and fibre quality parameters.

Keywords

General Combining Ability and Specific Combining Ability.

Abstract

The stability of 58 genotypes of American cotton comprising of 10 parents, their 45 hybrids produced in diallel fashion (without reciprocals) were evaluated in three environments for yield and its component characters. Significant E+(G x E) interactions showed differentional response of genotypes under different environments. Stability parameters revealed that the hybrids NH-452 x RAH-2211, DHY-286-1R x JK-276-10-5 and NA-1325 x RAH-101 found stable over the locations with high seed cotton yield, regression near unity and non significant deviation from regression.

Keywords

Stability, Regression Coefficient, G X E Interaction.
