浙粳66(即79—66)是浙江省农科院水稻所用矮粳23作母本,百哥作父本杂交的F_1经花粉培养选育而成。1978年定型,1979—1982年参加了鉴定、联品、区试等各级圃场试验,同时进行试种示范。表现比更新农虎早熟3—4天,并有所增产,抗稻瘟病和白叶枯病的能力比更新农虎强,耐寒性较强,适应性较广。现已经浙江省农作物品种审定委员会审定,列为全省推广品种。一、产量表现四年来,浙粳66参加了各级圃场试验,表现都比对照更新农虎增产。1981年参加省区域试验在当年不良的天气条件和病害流行下仍表现稳产。据全省29个试点统计,平均亩产638.7斤,比对照增产4.26％,差异达到显著标点。另据绍兴、杭州、宁波三地区的
Zhejiang Japonica 66 (ie, 79-66) is a hybrid F1-dwarf japonica rice used by Zhejiang Academy of Agricultural Sciences as a female parent and a male parent of F1 hybrid obtained by pollen culture. 1978 stereotypes, 1979-1982 participated in the appraisal, the joint, the district test and other nursery field test at the same time, tryout demonstration. Performance than the updated Nonghu early maturity 3-4 days, and have increased yield, resistance to rice blast and bacterial blight more powerful than the updated farming tiger, cold strong, adaptable. Zhejiang Province has now been examined and approved crop varieties Commission, listed as the province to promote varieties. First, the production performance In the past four years, Zhejiang, Japonica 66 participated in the field test at all levels, performance than the control update Nonghu increase production. In 1981, participating in provincial and regional trials still showed steady production in bad weather conditions and epidemic diseases of the current year. According to the province’s 29 pilot statistics, the average yield of 638.7 kg per mu, 4.26% increase over the control, the difference reached a significant punctuation. According to Shaoxing, Hangzhou, Ningbo, three regions
