摘要
2002-2004年在广西平南县稻瘟病重发区建立自然病圃，对2384份早晚造材料进行鉴定。结果表明，该自然病圃早造发病较重（叶瘟除外），晚造发病较轻，早造是抗性材料最佳筛选鉴定季节；诱发品种的选择应把握早、中、晚熟品种的搭配，以满足不同熟期抗病材料筛选的需要；双亲或其中之一具有抗病血缘，有助于筛选到稻瘟病抗性强的选系材料。
In 2002-2004, a natural nursery of rice blast was established in severe occurrence region ot rmgnan County in Guangxi, and 2,384 late rice materials were tested and identified. The results showed that rice blast was severe in early rice （except the leaf blast）, but was lesser for late rice ; early cropping season was the best to select and identify the resistance materials. The breeding of induction should pay more attention to mixture of early, middle and late varieties to supply the need of resistant materials with different maturities; either parents or at least one of that having blood relationship resistant to blast would be contributed to select materials with strong resistance to rice blast.
