Genetic studies in rice (Oryza sativa L.). XVI. inheritance of panicle type and spreading panicle branch

Inheritance interrelationship of two panicle characters, viz., panicle type and spreading panicle branch were studied in the eross D 6-2-2 x HY-256 Purple of rice. Lax panicle was found to be monogenic while spreading panicle branch was under the control of two complementary and two inhibitory duplicate genes. Tight linkage between the gene for lax panicle and one of the two inhibitory duplicate genes for spreading panicle branch was detected.
