Summary
An investigation of the genetic control of self-incompatibility in an F1 family of L. perenne L. using the pollen-stigma reaction indicated the involvement of more than two multiallelic loci. Pollen control was found to be gametophytically determined. Results indicated that the genetic control of self-incompatibility in L. perenne is similar to that in L. rigidum and L. multiflorum. It is suggested that not all alleles in pollen and pistil have to be matched to produce an incompatible reaction in Lolium species, in contrast to the system found in other self-incompatible grasses.
