利用田间自然诱发稻瘟病圃抗性鉴定技术对2002～2007年间4 029份次水稻材料的稻瘟病抗性进行了评价,结果表明,有1 594份次表现抗病,2 435份次表现感病,分别占总份次的39.56%和60.44%。并就如何改进稻瘟病抗性鉴定技术提出了见解,讨论了稻瘟病抗性评价在品种审定、抗病育种和安全生产上的意义。
The rice blast resistance of 4 029 rice cultivars from 2002 to 2007 was evaluated by field-induced resistance evaluation of rice blast disease-resistant nursery. The results showed that there were 1 594 secondary resistances and 2 435 secondary susceptibility tests , Accounting for 39.56% and 60.44% of the total respectively. Some suggestions on how to improve the identification technology of rice blast resistance were discussed. The significance of rice blast resistance evaluation on variety validation, disease resistance breeding and safety production was discussed.
