Cooperative research of three laboratories was performed to elucidate the speciation process of amphidiploid species in genus Brassica by investigating genes responsible for interspecific incompatibility and breakdown of hybrid embryos and mechanisms of self-compatibility. We identified QTLs of the strengths of interspecific incompatibility and embryo breakdown, which are clues to identification of the genes. Several S genotypes were found in three amphidiploid species, and mutations of dominant S haplotypes were considered to be the cause of self-compatibility.

三个实验室的合作研究通过研究负责种间不亲和和杂交胚胎破裂的基因以及自亲和机制来阐明甘蓝属双二倍体物种的物种形成过程。我们鉴定了种间不相容性和胚胎破裂强度的 QTL，这是鉴定基因的线索。在三个双二倍体物种中发现了几种S基因型，并且显性S单倍型的突变被认为是自交亲和性的原因。
