为筛选出适合百色右江河谷一带土质、气候、具有高产、稳定、抗逆性强等综合性状优良的水稻杂交品种,在相同栽培管理水平条件下,对12个水稻杂交新品种产量及性状进行鉴定。结果表明:天优湘99、深两优5845、深两优8386产量分别比对照特优63增产46.0kg/667m2、38.3kg/667m2和31.3kg/667m2,增幅均在5%以上,分蘖力和抗倒性强,且后期熟色好,综合表现较好,可在百色地区扩大种植区域和示范种植。

With the same conditions of fertility and management, the yields and traits of 12 varieties are identified. The results show that： the yield of Tianyouxiang 99,Shenliangyou 5845 and Shenliangyou 8386 are 46.0kg,38.3kg and 31.3kg per 667m2 respectively higher than that of the contrast, all of which rate increase above 5%. With stronger ability of tillering and lodging resistance, better maturing appearance and general performance, three varieties of Tianyouxiang 99,Shenliangyou 5845 and Shenliangyou 8386 could be demonstration and extension in Baise region of Guangxi.
