Summary Inheritance studies of purple pigmentation in T-160 x AC-177 revealed that purple colour in the coleoptile is based on four genes (Pc 1 , Pc2, I-Pc, Ai-Pc), in the internode on two genes (Pin a1 , Pin a2 ), in the junctura on three genes (Pja, Pjb 1 , Pjb 2 ) and in the apiculus on three genes (Pa, I-P, Ai-P). For panicle density monogenic segregation (Lx) was obtained. Linkage was established between the genes for the apiculus (Pa and Ai-P), panicle density (Lx), the internode (Pin a ), the coleoptile (Ai-Pc) and the junctura (Pja), in that sequence. This linkage group forms part of the IV ‘mp’ group of Misro et al. (1966) which corresponds to the ‘g’ group of japonica. The two anti-inhibitory genes Ai-Pg and Ai-Pau of the linkage group Ai-Pg=Ai-Pc=Ai-Pau reported earlier (Dhullappanavar et al., 1975) are also allotted to the IV linkage group of Misro et al. (1966) since Ai-Pc is placed in that group in the present studies.
