Abstract

A study of parent progeny regression analysis and heritability in narrow senso between F, and F, population of three inter varietal crosses for six quantitative traits indicated that the correlation and regression co-efficients between F mean and corresponding parental F values were significant for plant height, ear length and 100 grain weight in one cross, number of leaves and ear weight in another cross and plant height and number of leaves in a third cross. This indicates that the transmission of genetic potentialities from F, to F, is more and is attributed to additive gene effects. Hence, the scheme of selection in the segregating game- rations will be effective for these characters of respective crosses. The correlation and regression co-efficients between F, mean and corresponding parental F, values were not significant for grain yield in all the three crosses.
