中稻新品种引种研究

Introduction Study on New Medium Rice Varieties in 2007

[目的]筛选出适合滁州市生产需要的高产、优质、抗性好的中稻品种。[方法]以Ⅱ优838为对照品种,对引种的4个中稻新品种中浙优1号、华胜2号、天丰优084、协优982的农艺性状、经济性状、生育特性、抗性及产量进行综合评价。[结果]各品种在0.05水平单产区组间无显著差异、品种间差异显著,5个中稻品种的产量排序是天丰优084>中浙优1号>Ⅱ优838>协优982>华胜2号。天丰优084、中浙优1号的产量分别为9 540.09、497.5 kg/hm2,比对照Ⅱ优838分别增产3.50%、3.04%。[结论]天丰优084和中浙优1号适宜在滁州市推广应用。

[Objective] The research aimed to screen out medium rice varieties with high yield, good quality and resistance for the production demand in Chouzhou city. [Method] With ⅡYou 838 as control variety, the agronomic traits, the economic traits, growth characteristics, resistance and yield of 4 new introduced medium varieties including Zhongzheyou 1, Huasheng 2,Tianfengyou 084 and Xieyou 982 were evaluated comprehensively. [ Result ] The unit yield of each variety had no significant difference among different plots and had a significant difference among different varieties. The yield of 5 medium rice varieties in order was Tianfengyou 084 〉 21aongzheyou 1 〉 Ⅱ You 838 〉 Xieyou 982 〉 Huasheng 2. The yield of Tianfengyou 084 and Zhongzheyou 1 were 9 540.0 and 9 497.5 kg/hm^2 resp., which were increased by 3.50% and 3.04% than control Ⅱ You 838. [ Conclusion] Tianfengyou 084 and 21aongzheyou 1 were suitable for being popularized and applied in Chuzhou city.
