黑龙江省第一积温带水稻对纹枯病的抗性分析
Resistance Analysis of Rice Sheath Blight in the First Accumulated Temperature Zone of Heilongjiang
摘要
Abstract
Rice sheath blight of 55 rice varieties and germplasm resources were investigated by routine planting in a field plot to determine the occurrence of rice sheath blight in the first accumulated temperature zone in Heilongjiang, and discuss the resistance type. The results indicated that the 55 rice varieties and germplasm resources had different degrees of rice sheath blight, the average field disease cluster rate was 58.4％, the amplitude was 25.2％ to 100.0％, the average disease index was 52.2, only'Songnian 4'expressed resistance, 13 rice varieties, 'Song538', 'Songjing 19', 'Songnian 1', 'Songjing 28', 'Songjing 48', 'Song 536', 'Songjing 3', 'Songjign 15', '98131', 'Songjing 10', 'J36', 'J39'and'J42', expressed medium resistance, the resistant varieties took up 1.8％, the medium resistant varieties took up 23.6％, and the overall resistance ratio was 14:41.关键词
