【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。更多还原

【Abstract】 [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.更多还原
