This study was to understand the variation of cultivated yam in Taiwan. The diversity of RAPD(random amplified polymorphic DNA) was investigated. The main results were summarized as follows: 1.Significant differences in D. alata clones were detected

本研究為瞭解臺灣地區栽培種山藥種山藥種內之變異,進行核酸逢機增殖多型性(random amplified polymorphic DNA, RAPD)歧異度分析,藉由品系間之相似係數及分群分析之結果探討其種內的變異情形。結果:1)田薯(D.alata)臺灣品系與美國品系間有差異。全部品系可分為3群,其中A20-A33之品系,顯然與其他兩群之品系不同;2)懷山藥(D. batatas)臺灣品系與日本品系間無顯著差異,且相似性高,可能為相同品種群。
