中浙1号是浙江省农科院和中国水稻所育成的迟熟高产早籼新品种。1981年秋季定型以来,通过省协作鉴定、品比,1986、1987年参加浙江省早稻区域试验,同时参加宁波、衢州、舟山等市区试和大面积试种示范,均一致表现比对照种广陆矮4号增产显著,其抗性、米质亦比广陆矮4号好,而热期稍迟。已于1988年和1989年分别在衢州市和宁波市品种审定通过。闽、湘、赣等省已引进试种。一、选育经过和产量表现中浙1号的组合方式是IR24/原丰早//竹科2号。1975年秋在福建省同安农场加代育种时,选用IR24/原丰早F_6代的优良单株与高产品种竹科2号杂交,经多代选育,于1981年秋季定型,冬季在海南岛陵水县繁种,1982、1983年在浙江省农科院内进行鉴定、
Zhejiang No.1 is a late-maturing and high-yielding early indica new variety bred by Zhejiang Academy of Agricultural Sciences and China Rice. Since the establishment of the model in the autumn of 1981, it has been identified by the collaboration of provinces, and the ratio was taken in the trial of early rice in Zhejiang Province in 1986 and 1987. At the same time, it took part in pilot and large-scale demonstration projects in urban areas of Ningbo, Quzhou and Zhoushan, Land short 4 yield significant, its resistance, quality is also better than Guanglu short 4, while the heat is late. In 1988 and 1989, respectively, in Quzhou City and Ningbo City, approved by the species. Fujian, Hunan, Jiangxi and other provinces have introduced test species. First, after breeding and production performance in the combination of Zhejiang No. 1 is IR24 / early abundant bamboo // bamboo Branch No. 2. In the autumn of 1975, Tong’an farm in Fujian province was re-breeding, and the excellent single plant of IR24 / Haifeng early F6 generation was crossed with Zhushu No.2, a high-yielding variety. After several generations of breeding, the plants were sown in the autumn of 1981 and winter in Lingshui of Hainan Island County species, 1982, 1983 in Zhejiang Academy of Agricultural Sciences identification,
