Inheritance of Amylose in Two Hybrid Populations of Rice.

A suggested explanation for the inheritance of amylose in the two crosses studied is that the parental mean difference of 4.5 to 7.0% amylose in the C.I. 9444 X P.I. 215936 cross was controlled by one pair of genes of major effect and modifying genes of minor effect. The major gene for high amylose was incompletely dominant to its allele. In the Nato X Asahi cross, the parental mean difference of 2.5% was controlled by a few pairs of modifying genes of small and approximately equal effect. Both Nato and Asahi possessed the same or a similar gene of major effect for low amylose. The results of this study indicate that selection for amylose on the basis of single F2 plant values would be effective in populations derived from crosses in which the parents differed to any practical extent in amylose content. In crosses in which the parental difference was relatively small, selection would be effective, but to a lesser degree.
