Genetics of protein distribution in the F1 rice hybrids

Abstract

The present work deals with the preliminary observations on protein distribution, cooking quality and other characters of the F, hybrids between Cherumodan and Adt-27. The hybrid resembled Cherumodan in height and flowering habit. Cooking quality was better than either of the parents. The prolein distribution in Cherumodan was peripheral, while in Adt-27 it was deeply distributed with decreasing intensity from the periphery towards the interior. In the hybrid the protein bodies were uniformly distributed from the periphery towards the interior of the grain. The protein content, was the same as that of Adt-27, but due to its well distributed nature, protein loss due to milling and polishing of the grain would be much less. The results indicate that breeding and selection for improving the protein profiles of the grain could be effective and that utilization of the established varieties in such breeding programmes would be desirable.
