Frequencies of reciprocally compatible single, three-way and double crosses as determined by the number of S-homozygotes, the number of lines per S-homozygote and the types of inheritance of incompatibility in cruciferous crops

Abstract

The low number of useful S-alleles in several species and varieties of cruciferous crops (Brassica, Raphanus) may hamper the set-up of a practical programme of hybrid breeding based on sporophytic one-locus incompatibility. Few S-alleles may considerably reduce the number of reciprocally compatible crosses and therefore restrict the possibilities of… (More)
