摘要
对云南油菜种质资源 317份的抗 (耐 )病毒病、菌核病、霜霉病进行鉴定研究 ,结果为 :云南省的地方油菜种质资源中虽无对病毒病、菌核病、霜霉病免疫的品种 ,但存在着高抗 (耐 )病毒病、菌核病和霜霉病的种质资源。其中 ,在芥菜型油菜中鉴定出高抗 (耐 )病毒病种质资源 11份 (高抗 3份 ,高耐 8份 )、高抗 (耐 )菌核病的种质资源有 3份、高抗 (耐 )霜霉病种质资源 1份 ;在白菜型油菜中鉴定出高抗 (耐 )病毒病种质资源 1份 ;甘蓝型油菜无高抗 (耐 ) 3类病的种质资源。云南省大部份油菜种质资源对 3类病的抗性为低感至高感 ,占油菜资源总数的 89 4%。
Resistance of 317 Yunnan rape germplasm to virus, Scerotinia scerotiorum and Peronospora parasitica were evaluated (tolerance). Results were as follows:11 germplasm with high resistance (tolerance) to virus, 3 with high resistance(tolerance) to sclerotiniose, 1 with high resistance (tolerance) to downy mildew in Brassica juncea type of rape germplasm; 1 with high resistance (tolerance)to virus in Brassica campestris (including Brassica chinensis ) type of rape germplasm was screened. No one with high resistance (tolerance) to virus, sclerotinose and downy mildew in Brassica napus type of rape germplasm was screened. Most of rape germplasm, which amount to 89.4% of all the germplasm in Yunnan. Are no resistance to three kinds of desease.
