In an intervarietal cross between IR 8 and Wanar 1, inheritance of pigmentation in coleoptile, leafsheath, auricle, node, internode, septum and glume was studied . A pleiotropic gene conditioning pigment in all these parts has been identified which may probably be one of the basic genes for anthocya

โฆ Synopsis
Genetic analysis of ten characters in a rice cross M 18 ร T979 revealed the interaction of duplicate, complimentary, inhibitory and anti-inhibitory genes in conditioning pigment in eight characters and in determining flowering and growth habit. The action of genes and their interactions indicated by complex ratios for all the ten characters are claimed to be the first reports, pleiotropic action of two complementary genes and four duplicate genes has been detected.

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
