Abstract

Thermo-nonresponsive genotypes, Pavon '5' and Harrier '5' and photoperiod-responsive genotype Kalyan 50na exhibited positive gca effects for days to heading and grains/spike, and negative for grain weight and grain yield, while for temperature- responsive but photoperiod-neutral genotypes HD 2009 and WL 711 the situation was reversed. The positive gca effects of Chat '5' in pooled analysis of all genotypes for days to heading, grains/spike and spike productivity changed into negative estimates in the analysis of the four CIMMYT genotypes. The hybrids exhibiting positive sca effects for grain yield involved parents differing in their photothetmo responses.
