摘要
1987年～1990年,采用人工接菌的方法,对山西省4070份谷子品种资源进行了抗粒黑穗病鉴定,从中筛选出无病品种5份,高抗品种16份,中抗品种14份。研究结果表明,谷子品种资源对粒黑穗病的抗性存在着明显的差异。谷子品种的抗病性与品种原产地的生态条件有一定关系。不同粒色的谷子品种其抗病性是不同的。谷子品种对粒黑穗病的抗性能力比较稳定。
4070 foxtail millet varieties resistant to grain smut from Shanxi province were identified with artificial fungus from 1987 to 1900. 5 disease—free varieties, 16 high resistant varieties and 14 mid resistant varieties were screened. The study showed that resistance of foxtail millet varieties to grain smut were different. Discase resistance of varieties were related to environment of their region. Also disease resistance were linked with grain colour of varieties. Resistance of foxtail millet varieties to grain smut were relatively stable
