1 引 言 水稻品种作为重要的生产资料,具有明显的增产潜力,可以为社会创造出更多的粮食和财富。所以,人们都在努力选育、示范新品种。新品种的应用,除了靠自己育成外,引进筛选出适于本地区种植的新品种,也是一条重要途径,而且具有多、快、好、省的特点。本课题基于这一思路,1986年从东北和本区采集了38个品种,作了筛选研究。两年结果表明,至少有15个品种优于对照品种农院7—1,有5—6个品种的丰产性、适应性、抗病性表现均很好,在我区有重要推广价值。
1 Introduction Rice varieties as an important means of production have obvious potential for increasing production and can create more food and wealth for the society. Therefore, people are working hard to breed and demonstrate new varieties. Application of new varieties, in addition to their own breeding, the introduction of screening for the planting of new varieties in the region is an important way, but also with more, faster, better, provincial characteristics. This topic is based on this idea. In 1986, 38 varieties were collected from the northeast and the region and made a screening study. The results of two years showed that at least 15 cultivars were better than the control cultivar 7-1 and had 5-6 cultivars of high yield, adaptability and disease resistance, which had great promotion value in our district.
