Abstract: The material comprised of five generation of two crosses namely AURC 8 ï‚´ ADT 36 and AURC 10 ï‚´ ADT 43. Among the parents, ADT 43 was found to be good performer for grain length, grain L/B ratio, kernel L/B ratio and grain yield per plant. The cross AURC 8 ï‚´ ADT 36 exhibited high per se performance for grain length, grain breadth, kernel length, kernel breadth and grain yield per plant. From generation mean analysis, the grain length, grain L/B ratio, kernel length, kernel breadth and grain yield per plant were predominantly, controlled by additive gene effects followed by additive ï‚´ additive interaction effects. Hence simple pedigree breeding procedure is suggested for improvement of these characters.
