云南省农科院植保所于1976～1982年鉴定水稻品种抗稻瘟病的能力,共鉴定了本省地方品种3109份,国外品种3044份,全国各地(包括本省)品种3180份,共9333份。 1.该研究明确了外引品种在昆明地区,对抗叶瘟的品种,其比例秈稻均大于粳稻,而对穗瘟的抗性表现有减退现象。 2.云南地方品种资源对叶瘟的抗性反应次序为:粳<秈<粳陆稻;而对穗瘟的抗性反应是:秈<粳<粳陆稻。粳陆稻对苗、叶、穗瘟抗性较稳定,是开发抗病基因,值得重视的品种资源。
Yunnan Academy of Agricultural Sciences Institute of Plant Protection identified the blast resistance of rice varieties from 1976 to 1982, identified a total of 3109 local varieties of the province, 3044 foreign varieties, throughout the country (including the province) 3180 varieties, a total of 9333 copies. 1. The study identified the introduction of exotic varieties in Kunming, the fight against leaf blast varieties, the proportion of indica rice are larger than japonica rice, while the resistance to head blast decreased performance. The resistance sequence of Yunnan local cultivars to leaf blast was japonica Upland rice. Japonica rice is relatively resistant to seedling, leaf and ear blast, and is a variety of resources that is worth developing for developing disease resistance genes.
