水稻新品种花育1号及花育2号是由天津市农科所提供杂种一代花粉,经中国科学院遗传所用花粉培养,以单倍体育种法共同育成的。其育成过程如下: 一九七○年杂交,组合为日本晴×千钧棒,一九七一年从杂种第一代取花粉进行培养,是年冬长出花粉植株,先种于温室,一九七二年春季移到田间,一九七三年将各花粉植株所得的种子按株系种成小区,进行小区鉴定,有两个株系表现性状整齐优良而中 The new rice varieties Huayu 1 and Huayu 2 are hybrid generations of pollen supplied by Tianjin Agricultural Science Institute. The pollen cultivars inherited from Chinese Academy of Sciences were bred by haploid breeding method. The breeding process is as follows: In 1970, the hybrid combination of Nipponbare × Qian Junbang, from the first generation of hybrid pollen in 1971 to be cultured, winter is pollen plants grow, first planted in the greenhouse, a nine In the autumn of 1972, he moved to the field. In 1973, the seeds of each pollen plant were planted in different plots according to their lines, and the community was identified. Two of the lines showed fine and fine traits
