稻曲病历来被认为是丰产性病害,一直没有受到重视。近年来,随着水稻单产水平的不断提高,稻曲病的发生也日趋严重,已成为影响水稻生产的主要病害之一。据统计,1986年我省发病面积约占全省水稻面积的21%左右,严重的减产达20%。关于稻曲病的危害、病理、毒性、发生规律及药剂防治等方面的研究已经有过报道,但关于稻曲病的发生在品种之间是否存在差异以及在育种上应注意哪些性状的报道尚属少见。本文即在于针对这方面的急切需要,进行了初步的试验和分析,为水稻抗稻曲病育种工作提供参考。 Fallaceae has always been considered a high yield disease, has not been valued. In recent years, with the continuous improvement of rice yield, the incidence of false smut is also becoming more and more serious, which has become one of the major diseases that affect rice production. According to statistics, in 1986, the incidence of disease in our province accounted for about 21% of the province’s rice area, a serious reduction of 20%. There have been reports on the damage, pathology, toxicity, occurrence and control of False Smut, but there are still some reports about the occurrence of False Smut Is rare. This article is in response to the urgent needs in this area, conducted a preliminary test and analysis of rice anti-smut breeding efforts to provide a reference.
