Restriction fragment length polymorphism analysis, using peroxidase, O-methyltransferase, phenylalanine ammonia-lyase, and coniferyl alcohol dehydrogenase cDNAs isolated from Stylosanthes humilis, as probes, provided molecular evidence for the genetic origin of the naturally occuring allotetraploid genotype Stylosanthes hamata cv. Verano (2n = 4x = 40). Hybridization patterns strongly suggest that the likely progenitors of S. hamata cv. Verano were a diploid S. humilis (2n = 2x = 20) and a diploid S. hamata (2n = 2x = 20) species.
利用过氧化物酶、O-甲基转移酶、苯丙氨酸解氨酶和松柏醇脱氢酶 cDNA 进行的限制性片段长度多态性分析，作为探针，为天然存在的异源四倍体基因型 Stylosanthes hamata cv. Verano（2n = 4x = 40）的遗传起源提供了分子证据。杂交模式强烈表明，S. hamata cv. Verano 的可能祖先是二倍体 S. humilis（2n = 2x = 20）和二倍体 S. hamata（2n = 2x = 20）物种。
