The two locus gametophytic self-incompatibility system of the grasses entails a maximum of four different S-Z specificities in the diploid pollen of tetra-ploid individuals. It is not known for certain whether only one S-Z pair in such pollen needs to be matched by the same pair in the stigma for incompatibility to occur (hypothesis 1) or whether all such pairs have to be matched (hypothesis 2).This paper, the first of three, concerns the results obtained from the application of the first stage… CONTINUE READING
