โœฆ Synopsis

The inheritance of anthocyanin pigmentation and the interrelationship between genes governing anthocyanin pigmentation in different parts of the rice plant and genes governing panicle density were studied in the cross Suma x Wanar-1.

A ratio of 45 pigmented: 19 non pigmented was realised for anthocyanin accumulation in sheath, nodal ring, internode, leaf tip, leaf margin and apiculus whereas a ratio of 3 normal : 1 laxy was observed for panicle density. Pleiotropic action of a basic gene (A) and each of the two complementary duplicate genes (P, or Ps) was detected. A linkage group of genes localising pigment in six plant parts was identified, the sequence of genes being P,,

Twelve characters showed segregation for pigmentation in the rice cross T-141 z K-44-1. Inheritance was complicated by the involvement of the unusual number of genes ranging from two to five with different modes of action such as complementary, duplicate, inhibitory, anti-inhibitory etc. F2 ratios i

The inheritance of phosphorous (P) - deficiency tolerance in rice was investigated by a sevenparent diallel. The parent materials involved were four P-efficient (IR20, IR54, IR28, and Mahsuri), one moderately P-efficient (TN1), and two P-inefficient (IR31406333-1 and IR34686-179-1-2-1), genotypes. R

Eight dull mutants that lower the amylose content of rice endosperm as well as waxy mutant and a cultivar with common grains were crossed in a diallele manner. The amylose content of F1 and F2 seeds was determined on the basis of single grain analysis. It was concluded that the low amylose content o
