Self-incompatibility is the system that inhibits pollen germination and pollen tube growth by self-pollen. This trait is important for the breeding of and species. In these species, self-incompatibility is governed by the locus, which contains three linked genes (a set called the haplotype), i.e., -locus receptor kinase, -locus cysteine-rich protein/-locus protein 11, and -locus glycoprotein. A large number of haplotypes have been identified in , , and to date, and the nucleotide sequences of their many alleles have also been registered. In this state, it is important to avoid confusion between haplotypes, i.e., an identical haplotype with different names and a different haplotype with an identical haplotype number. To mitigate this issue, we herein constructed a list of haplotypes that are easily accessible to the latest nucleotide sequences of -haplotype genes, together with revisions to and an update of haplotype information. Furthermore, the histories of the -haplotype collection in the three species are reviewed, the importance of the collection of haplotypes as a genetic resource is discussed, and the management of information on haplotypes is proposed.
自交不亲和性是一种通过自身花粉抑制花粉萌发和花粉管生长的系统。这一特性对于[具体物种1]和[具体物种2]的育种很重要。在这些物种中，自交不亲和性由S位点控制，该位点包含三个连锁基因（一组称为S单倍型），即S位点受体激酶、S位点富含半胱氨酸的蛋白/S位点蛋白11和S位点糖蛋白。迄今为止，在[具体物种1]、[具体物种2]和[具体物种3]中已鉴定出大量的S单倍型，并且它们许多等位基因的核苷酸序列也已登记。在这种情况下，重要的是要避免S单倍型之间的混淆，即具有不同名称的相同S单倍型和具有相同S单倍型编号的不同S单倍型。为了缓解这个问题，我们在此构建了一个S单倍型列表，该列表易于获取S单倍型基因的最新核苷酸序列，并对S单倍型信息进行修订和更新。此外，还回顾了这三个物种中S单倍型收集的历史，讨论了收集S单倍型作为遗传资源的重要性，并提出了S单倍型信息的管理方法。
