随着以秦油2号为代表的杂交油菜的大面积推广使用,油菜单产大幅度提高,不仅增伽了油农的经济收入,而且产生了巨大的社会效益。但杂交油菜种子的纯度问题到目前为止仍然对杂交油菜的产量存在着潜在的威胁,成为进一步提高油菜单产,扩大杂交油菜种植面积的限制因素。1992年安徽省近百万亩杂交油菜种子纯度只有70%左右,造成了一定程度的减产,农户对杂交油菜产生了忧虑。为此,合肥市农业科技
With the large-scale popularization and utilization of hybrid rape represented by Qinyou 2, the yield of rapeseed increased significantly, which not only increased the economic income of oil-farmers but also produced tremendous social benefits. However, the purity of hybrid rapeseed seeds still poses a potential threat to the yield of hybrid rapeseed so far, which has become a limiting factor for further improving the yield of rapeseed and increasing the planting area of hybrid rapeseed. In 1992, nearly 100 million mu of hybrid rapeseed in Anhui Province was only about 70% pure in purity, causing a certain degree of yield reduction. Farmers’ concern about hybrid rapeseed occurred. To this end, Hefei Agricultural Science and Technology
