我国稻曲病分级标准的研究与应用现状

Research and Application Status of Severity Grading Standards of the Rice False Smut Disease in China

对我国稻曲病分级标准的研究与应用现状进行了梳理。由于我国不同稻区水稻品种、耕作制度和气候环境的差异,以及稻曲病本身病征的特殊性,制定普适性的全国统一标准尚有难度。根据植保统计或抗病性评价的不同需要,选择合适的分级标准以满足不同需求是目前稻曲病研究中普遍采取的做法;亦有不少地区根据自身情况,通过室内考种建立符合当地实际的地方分级标准。目前我国主要有两套分级标准应用较为广泛,在标准的制定和采用上仍需加强攻关。

The status of the research and application of rice false smut(RFS)disease severity grading standards in China was reviewed in this paper.Due to the differences in rice varieties,farming systems and climatic environments in different rice regions in China,and the particularity of the disease symptoms of RFS,it is still difficult to formulate a universal national unified standard.According to the different purposes of plant protection statistics or the evaluation of resistance to RFS of rice varieties,the selection of appropriate grading standards to meet the different needs is currently a common practice in the research of RFS disease.Based on the local conditions,different grading standards have been established in different rice regions by plant laboratory test.Currently,there are two sets of grading standards are widely used in China.The research of formulation and adoption of grading standards for RFS is still need to be strengthened.
