摘要
多年多品种接种不同地区菌源试验表明,不同品种的抗褐斑病性存在显著差异,抗褐斑病稳定性也存在显著差异。参试品种以甜研3号、双丰8号、B-RP为高抗病品种,双丰8号品种有较高的抗病稳定性,是优良的抗病种质源。不同地区菌源致病性无显著差异。
The experiments on varieties of inoculation fungus source came from different areas were worked for several years. The results shown that. The resistances and its stabilities on leaf spot have significant differences in different Tarieties. Among varieties used in the experiment, Tianyan-3, Shuangfeng-8, t B-RP are high resistance. Shuangfeng-8 is good germplasm source for resistance, because it has high stability. Pathogenicity of fungus have no significan differences in the different areas.
