β¦ Synopsis
Four dwarf mutants derived from the rice variety H-4 were found to differ not only in height but also in other characters, probably as a result of pleiotropic gene action. Time-to-flowering, tiller number, spikelet number, grain size and flag leaf area were affected and diallel analysis of parents and FI hybrids showed additivity and various degrees of dominance with no evidence of gene interaction. Analyses of height differences in the F l and F 2 showed incomplete dominance for tallnes in the H-4 parent and evidence that four separate loci with various degrees of dominance determined dwarfism.

Inheritance of scent in rice and its association with pigmented characters were studied in T-141 Γ K-44-1. Four complementary genes appeared to control scent, one of them showing linkage with a complementary gene for glume colour and a supplementary gene for red pigment in apiculus. This group form
