Bidens pilosa var. radiata, one of the rapid expanding invasive weeds, has become prevailing throughout Taiwan. A study on the result enhanced by the breakdown of geographic isolation with the native varieties in genetic variation, population structure and introgressive hybrization is really in need. In this study the genetic variation and population structure among the varieties of Bidens pilosa complex were studied using ISSR markers.

在台湾Bidens pilosa种群在外部形态及分布上均非常类似，加上大花咸丰草又属极具侵略性的新归化种，在与其他自生变种又无明显隔离下，是否增加种间之交流与渐渗杂交之机会及对族群结构的影响，实有深入探讨之必要。
