The functional allele at the W locus is Ipmyb2, which was newly found in Chinese populations, and it differs mainly in the intron regions from those of the reported allele Ipmyb1; in comparison to Ipmyb2, the newly found second allele ipmyb2 has eight substitutions in the exons, a 6-bp deletion, and a 19-bp deletion, causing ORF shifting, and exists mostly in white-flowered individuals.

以上结果表明：1花青素代谢途径上酶基因的位点均有一定程度的多态，其中尤以ANS为最高；调控基因ipmyb2的核苷酸缺失造成该基因停止功能，使其纯合子的个体开白色花。2授粉者所介导的花色表型选择确实在中国种群中发生，有可能进一步增加花色代谢途径上基因位点的遗传变异。
