77年我省水稻不育系繁殖面积6800亩,比76年扩大58％,平均单产35斤。根据全省9个地区34个县37个典型材料统计,面积2451亩,平均单产达44斤。印江县,繁殖69.7亩,单产92斤。最高的凤冈县绥阳公社有2.5亩,单产达到232斤。为适应杂交水稻大发展的需要,根据各地的经验,拟定1978年水稻不育系繁殖技术要求,以供参考。
In 1977, the breeding area of rice CMS in our province was 6,800 mu, an increase of 58% over that of 76 years with an average yield of 35 kg. According to the statistics of 37 typical materials in 34 counties and 9 districts in the province, the area is 2451 mu with an average yield of 44 kilograms. Yinjiang County, breeding 69.7 acres, yield 92 pounds. The highest Fenggang Suiyang commune 2.5 acres, yield reached 232 pounds. In order to meet the needs of the great development of hybrid rice, according to the experience of different places, we formulated the technical requirements for breeding of male sterile lines in 1978 for reference.
