摘　　要：用优质、稻瘟病田间抗性强的日本品种轰早生作母本 ,分蘖力强、繁茂性好、抗稻瘟病的云南楚雄州农科所育成品种楚粳 4号作父本进行杂交 ,从F3 代系统开始 ,同时进行高产、品质、稻瘟病抗性、耐冷性同步鉴定 ,作为选拔的科学依据 ,经 5年 7代选育 ,育成了优质、高产、抗病的新品种合系 30号。Cooperation line No 30 was bred by crossing, using Todorokiwase as maternal parent, Chujing No 4 as paternal parent. Todorokiwase is a Japanese variety with good quality and strong resistance to blast. Chujing No 4 is a Yunnan variety with strong tillering and blast resistance. We evaluated apperance quality from F 3 generations and synchronously evaluated yield blast resistance, cold endurance and taste quality in the variety test, the evaluating results provided scientific basis for selection. Through five years and seven generations selection we obtain Cooperation line No 30 that have traits on good quality, high yield and blast resistance.
