Abstract
In a study of two spring wheat hybrids heritability estimates were very high for plant height, high for 1000 grain weight, intermediate for no. of grains/ear and very low for no. of ears/plant and grain yield/plant. No. of ears/plant had the highest positive correlation with grain yield/plant. Association of no. grains/ear with plant yield was much lower but significant. There was no significant relationship between 1000-grain weight and grain yield/plant. Correlations between yield components were very low. Negative correlation, which did not reach significance, was found between no. of ears/plant and 1000 grain weight in one cross. The results of this study indicated that no. of grains/ear was the most important character in selection for high grain yield.
