Abstract EN
Five parents and ten F1 crosses were grown in RCBD design with three replications 2010.
Correlation ,Path coefficient analysis and heritability were estimated for days to 75% flowering, plant height, flag leaf area, number of spikes/plant, spike length, number of effective tillers/plant, number of grains/spike, 1000 grain weight, biological yield/plant, grain yield/plant, harvest index and protein percent.
Broad sense heritability was found to be high in all characters; while high narrow sense heritability was found for days to 75% flowering and moderate for protein percent.
Presence of gene action in traits like plant height, flag leaf area, spikes/plant, number of grains/spike, 1000-grain weight and grain yield.
Significant and positive correlation was found between grains yield/plant and each of plant height, spike length, number of spikes/plant, number of grains/spike, 1000 grain weight, harvest index biological yield/plant, flag leaf area and number of effectivetillers / plant.
Path analysis revealed that number of spikes/plant had highest direct effect on grain yield/plant indirect effect through other characters which was used as index for the selection of high grain yield/plant.
