杂交水稻春制(繁)后的不育系再生利用技术是根据目前在生产上使用的野败型雄性不育系再生力很强的特性,利用早、中熟杂交稻组合春制(不育系春繁)后的不育系再生进行制种。1982年由京山县种子公司提出研究设想并付诸实施,1985年获得初步成功。1986年在全省五个县进行了试制。1987年在全省大面积示范2000余亩其中春制后再生制种示范1835亩,平均春制亩产149公斤,最高达140公斤,再生制种亩产54公斤,最高达256公斤,两季合计亩产203公斤;春繁后再生制种示范166亩,春繁亩产106公斤,再生制种亩产57公斤,两季合计亩产163公 The regeneration technology of CMS lines after spring (hybrid) in hybrid rice is based on the characteristics of reproductive ability of wild-type male sterile lines that are currently used in production. By using the combination of early maturity and medium maturity hybrid rice (sterile Department of spring and spring) after the sterile system of seed production. In 1982, Jingshan County Seed Company put forward its research ideas and put them into effect, achieving initial success in 1985. In 1986 in five counties in the province conducted trial. In 1987, a large-scale demonstration of more than 2000 acres in the province of which 1835 acres of reproductive seedlings after the spring, the average spring yield 149 kg per mu, up to 140 kg, reproductive system mu 54 kg, up to 256 kg, two seasons A total of 203 kilograms per mu; spring reproductive demonstration of 166 mu after spring, mu yield of 106 kg per mu, regenerative seed production of 57 kg per mu, two quarters of total 163 acres of mu
