| 摘 要： | 杂交稻黔优301于2001~2006年在贵州省不同海拔地区进行了各类试验,在贵州海拔400~1200 m的地区表现了良好的耐冷性和丰产稳产性,尤其是秋季水稻扬花季节受到低温危害的年份,显示出其耐冷优越性,获得较大幅度增产。一般产量为8.0 t/hm2左右,栽培试验最高产量达12.7 t/hm2。杂交稻种子的制种产量为3.0 t/hm2左右。

| Abstract: | Qianyou 301 bred by Guizhou Rice Institute and released by Guizhou Committee of Crops Variety Examination in 2004, was tested in different areas at the elevations of 400- 1200 meters in Guizhou during 2001- 2006. The results showed that Qianyou 301 had the good cold tolerance and high-stable yield and the yields of most rice varieties dropped because of cold weather at the heading period, but the yield of Qianyou 301 increased on a large-scale because of its good cold tolerance in 2002. The normal and most highest yield was 8.0 t/ha and 12.7 t/ha respectively, and its F1 yield was about 3.0 t/ha. |
