中籼水稻多品种(组合)引种对比研究

Introduction Comparative Study on Indica Rice Varieties(Combinations)

[目的]为水稻品种种植选择提供参考。[方法]选取7个品种（组合）参加展示,考察产量与质量性状、全生育期天数,并比较抗逆性。[结果]参加展示品种（组合）产量7 282.5-8 854.5 kg/hm2,产量水平表现较高,米质表现都比较好,全生育期142-145 d,抗性较好。[结论]7个品种表现均较好,建议继续示范推广。

[Objective]The aim was to provide references for selection of planting rice varieties. [Method]Selecting seven varieties（combinations） participated in the display, the yield and quality traits, whole growth period days and resistance were studied. [Result] The yields of varieties（combinations） participated in the display were 7 282.5-8 854.5 kg/hm2. The production levels performanced higher, and grain quality performance was better,and the whole growth period was 142-145 d, and resistance was better. [Conclusion]The performances of seven varieties were good, so it was recommended to continue demonstration.
