| 摘 要： | 采用１７个从北美新引进的胡麻品种（系），在自然重病地上进行了抗枯萎病性能的研究，结果表明，新引进品种（系）间抗枯萎病性能虽有差异，但均属抗病类型，它们的生物产量低于当地高抗枯萎病主栽品种陇亚７号，Ｖｉｍｙ，ＭｃＧｒｅｇｏｒ和Ｏｍｅｇａ生物产量位居第２和第３，与陇亚７号的差异较小，病死株率分别为７．２％，８．４％和７．９％，分别比陇亚７号低４．４，３．２和３．７个百分点，是抗病育种比较理想的亲本品种

| Abstract: | The research results of resistance to flax wilt are reported by experimenting with 17 flax cultivars newly introduced from North America that were infected seriously by flax wilt in a cultivated land.The results show all thecultivars can grow with an excelent resistance to flax wilt though they are different in the capability of disease resistance.They can be used as parents for resistance breeding. These introduced cultivars are lower in the bio yield than teh ck.Long ya No.7 which has a good power of resistance but Vimy,Mcgregor and Omega are better. |
