Inheritance of Kernel elongation in rice

Abstract

In the present investigations, an attempt was made to know the inheritance pattern of cooked kernel elongation in Mahsuri Mutant crosses. In all the three Mahsuri Mutant crosses, the frequency distribution of kernel elongation ratio of segregating populations always formed a bimodal curve. However, in crosses of Mahsuri Mutant and Mahsuri (even in the reciprocal cross) the bimodal curve progressed towards lower kernel elongation. So it can be assumed that this character may be governed from 1 or 2 loci. But in crosse of Mahsuri Mutant and 9192 a very smaller peak compared to the other was noted, hich denotes the predominance of one major gene along with few modifier genes.
