| 摘 要： | 分析了江西6个不同纬度、海拔地点32年以上的日平均气温,认为江西适宜用温敏型两用核不育系制种的地区在赣南及赣中南部,但这些地区繁殖不育系比较困难;温敏型不育系的种子繁殖可在海拔较高的山区进行.提出了在江西气温条件不同的地区分别建立制种基地和繁殖基地的设想,温敏型不育系种子还可在海南岛异地繁殖.

| Abstract: | The daily mean temperature over 32 years from six sites with different latitude or ele-vation in Jiangxi Province is analysized.It is suggested that the regions in southern Jiangxiand the southern part of central Jiangxi are suitable for seed production by usingthermo-sensitive dual-purpose genic MS lines,but it is difficult for the MS lines multiplyin these regions.The MS lines can be multiplied at hilly areas with higher elevations.Theproposal for setting up seed production bases and multiplication bases in the regions withdifferent temperature condition is offered.Also,the MS lines can be multiplied in HainanIsland. |
