黑龙江省牡丹江地区农科所,从一九七一年八月开展水稻单倍体育种技术的研究工作以来,诱导分化培养出大批绿色植株,并用三年时间培育出水稻新品种“牡花一号”。据一九七五年全地区区域性鉴定试验,该品种表现早熟(生育期115～120天),抗稻瘟病,生育整齐,长的清秀,秆强不倒伏,抽穗快,上的急,产量高(该所种植亩产达813.4斤,较同熟期对照品种北斗增产12.6%)。“牡花一号”的培育过程是:一九七二年七月接种花粉(其杂交一代组合是牡丹江四号×牡交28号),十二月幼苗室内移栽,一九七三年六至八月抽穗、成熟,一九七四年田间株系种植,即花粉二代,表现植株整齐,性状一致,早熟,抗稻瘟病,当年收后去海南岛加速
Heilongjiang Province Mudanjiang Agricultural Research Institute, from August 1971 to carry out rice haploid breeding technology research work, the induction of differentiation and cultivation of a large number of green plants, and three years to breed a new rice variety “ ”. According to the regional accreditation test conducted in 1975, the variety showed early maturity (growth period of 115-120 days), resistance to rice blast, regular birth, long and delicate appearance, strong stalk, rapid heading, high yield, High (the planting of mu up to 813.4 kg, compared with the same period control variety Beidou yield 12.6%). The cultivating process of “Muhua No.1” was: pollen was inoculated in July 1972 (its hybrid generation was Mudanjiang No.4 × Mujiao No.28), December seedling indoor transplanting, and 1973 To August heading, mature, cultivation of field lines in 1974, that pollen second generation, showing the plant neat, consistent traits, precocious, resistant to blast, then income to Hainan Island to speed up
