摘　　要：[目的]为探明利用云恢290的耐储藏基因选育的耐储藏杂交水稻新品系储藏优1号的耐储藏特性。[方法]将该品系与对照Ⅱ优838及汕优63的农艺性状进行调查比较,并采用加速老化试验比较其与籼稻、粳稻及杂交水稻材料的耐储藏特性。[结果]该品系农艺性状优异,人工加速老化后发芽率明显高于其他材料。[结论]储藏优1号有较好的耐储藏特性,适于大面积推广。[ Objective ] The aim of this study was to investigate the storage durability of a new line of endurable storage hybrid rice Chucangyou No. 1 selected by endurable storage genes of Yunhui 290. [ Method] Agronomic characters of the new line and the control Ⅱ you 838 and Shanyou 63 were comparatively studied, and storage durability of the new line and indica, japonica or hybrid rice were also comparatively analyzed by the accelerated ageing test. [ Result ] Agronomic characters of the new line were excellent, and germination rate in the artificial accelerated ageing test was significantly higher than those in other materials. [ Conclusion] Chucangyou No. 1 has the better storage durability, which can be used in large scale of extention.
