1986~1990年通过对中国水稻研究所保存的2185份浙江稻种资源的农艺性状鉴定,稻瘟病、白叶枯病、纹枯病、褐飞虱、白背飞虱的抗性鉴定,耐逆性鉴定和米质测定等多学科协作研究,明确了这些资源中的优异种质。根据其特性,可归为矮秆、大穗、大粒、米质优异,抗流行性病虫害能力较强,耐逆性较好和具有较多优良特性等5类。同时,我们还对优异稻种资源的利用作了评估。
Through the identification of the agronomic traits of 2185 Zhejiang rice germplasms preserved in China National Rice Research Institute from 1986 to 1990, the resistance and resistance to rice blast, bacterial blight, brown planthopper and white-backed planthopper, And rice quality measurement and other multidisciplinary collaborative research, identified the excellent germplasm in these resources. According to its characteristics, it can be classified into 5 categories: dwarf, big spike, big grain, excellent quality of rice, stronger ability of resistance to epidemic diseases and pests, better tolerance to stress and more excellent features. At the same time, we also evaluated the utilization of outstanding rice resources.
