Variation studies in African wild and cultivated rice species



Variation studies in African wild and cultivated rice species



Japan, National Institute of Genetics: Annual report No 29, 1978 [II]: 90-91



In mixed populations of Oryza sativa and O. glaberrima from Nigeria, ligule length and several other characters were distinct in the two species but some populations included a few plants with intermediate characters. The progeny from selfing such plants segregated for ligule length and had low seed fertility. These observations and studies of acid phosphatase isozymes indicated introgression between the two species.
