Isozymic variability of traditional rice (Oryza sativa L.) in Africa

A de Kochko. Theor Appl Genet. 1987 Sep.

Abstract

Eight hundred and thirtyone traditional varieties of rice, Oryza sativa L., were collected in Africa and analysed for their isozymic variability on 15 enzymatic systems, representing 37 presumed loci. There appears to be a correlation between the type of rice growing and the two groups Indica and Japonica. The degree of genetic diversity is nearly equal in African rice and the Asian one. Alleles due to introgression or mutational events were identified. The results suggest that the evolution of O. sativa is continuous in Africa by means of inter-subspecific or inter-specific crosses.
