水稻是福建省的主要粮食作物,稻谷产量占粮食总产量的85％左右。在稻作生产中,品种是最活跃的内在因素,历次更新品种都对粮食增产起了决定性作用。从1975年～1983年,全省水稻品种两次较大的更换,粮食单产由397斤提高到623斤。七年间每亩增产226斤,超过1977年以前28年的总增产数。今后如何创造出“优质、丰产、多抗、适应性强的品种,有必要对近十年育成品种的状况加以分析,此基础上探讨今后十年品种改良的相应技术。一、水稻常规育种近十年的状况
Rice is the staple food crop in Fujian Province, and rice production accounts for about 85% of the total grain output. In the production of rice, varieties are the most active internal factors, and all previous varieties have played a decisive role in increasing grain output. From 1975 to 1983, the province’s rice varieties twice larger replacement, grain yield increased from 397 pounds to 623 pounds. 226 kilograms per mu in seven years, more than the total increase of 28 years before 1977. In the future, how to create "high quality, high yield, multi-resistance, adaptability of varieties, it is necessary to analyze the status of bred varieties in the past decade, on the basis of the next ten years to explore the appropriate varieties of improved technology. Ten years of status
