棉花杂交组合品种比较试验

[目的]拓宽棉花品种遗传基础,选育棉花新品种。[方法]通过对11个棉花品种生育期、农艺性状、抗病性以及丰产性状进行综合分析,选育综合性状优良的新品种。[结果]丰产性状:籽棉产量最高的是HA419,其次是HA417,最低的是HA310,次低的是HA420和HA116。经济性状:籽指最高的是HA310,最低的是HA420;衣分最高的是HA417,其次是HA421和HA418,最低的是H39。[结论]品系HA417、HA419、HA421具有较高的推广价值;品系HA416、HA310、HA420可不再进入下一年度试验;其余可以继续试验以验证该品系的特征特性。

Comparative Experiment on New Hybrid Cotton Varieties

[Objetive] To broaden the hereditary basis of cotton varieties and select new varieties.[Method]Based on the comprehensive analysis about growing period, agronomic traits, disease resistance and high yield of 11 cotten varieties, the new varieties were compared.[Result]As for high yield, cotton yield of HA419 was the highest, HA417 was the second highest,HA310 was the lowest,HA420 and HA416 are the second lowest.As for economic traits, seed index of HA310 was the highest, the lowest was HA420.The highest lint percent was HA417, followed by HA421 and HA418, the lowest was H39.[Conclusion] The varieties HA417, HA419 and HA421 have a high value of popularization.The varieties HA416, HA310 and HA420 can no longer participate in test in the next year, and the rest can continue to test to verify the characteristics of the varieties.
