PLEIOTROPY AND LINKAGE IN RICE (ORYZA SATIVA L.). II. PLEIOTROPIC INHIBITORS AND ANTI-INHIBITOR, AND LINKAGE OF ANTHOCYANIN PIGMENTATION GENES: LEAF BLADE, INTERNODE, NODAL RING AND PANICLE BASE
Main Article Content
Abstract
Inheritance pattern of anthocyanin pigmentation in leaf blade, internode, nodal ring and panicle base of rice has been investigated in an intervarietal cross between the upland rice cultivars D 6-2-2 (green variety) and HY·256 Purple (purple variety). Three to five pairs of genes control the pigmentation of leaf blade (Fz ratio 39 : 25), internode (147 : 109), nodal ring (63 : 961), and panicle base (171 : 853). Two pleiotropic inhibitory genes and one anti-inhibitory gene show variable expression in these plant parts. Linkage has been established between the basic genes for pigmentation in leaf blade, internode and panicle base. This linkage group (Ppba-PI-Pin) probably forms a part of the II (lg) linkage group of Misro et al. (32), in which the genes Ppba and Pin for pigmentation in panicle base and internode are new additions.
