大豆不同品种农艺性状及产量的比较

Comparative study on the agronomic traits and yields of different soybean varieties

【目的】鉴定引进大豆品种(系)在新疆南疆地区的适应性和丰产性,为该地区麦茬复播大豆品种更新换代和推广应用提供科学依据。【方法】测定参加试验的27个大豆新品种(系)的农艺性状和产量,应用方差分析、相关分析、主成分分析和聚类分析等方法综合鉴定评价。【结果】产量最高的品种为SC15-11,产量为266.995 kg/667m^(2),与对照相比增产47.872%。产量与单株粒数呈极显著正相关(P<0.01),与单株有效荚数呈极显著正相关(P<0.01)。在欧式距离为5.00时可将所有材料分为3个类群,分别为高产、中产和低产品种。【结论】SC15-11、JO14和冀豆22等品种综合性状表现优,可在新疆南部地区试验种植。

【Objective】To identify the adaptability and high yield of introduced soybean varieties(lines)in southern Xinjiang in the hope of providing a scientific basis for the replacement and popularization of wheat stubble soybean varieties in southern Xinjiang.【Methods】The agronomic traits and yields of 27 new soybean varieties(lines)participating in the experiment were measured,and the methods of variance analysis,correlation analysis,principal component analysis and cluster analysis were used for comprehensive identification and evaluation.【Results】The variety with the highest yield was SC15-11,with a yield of 266.995 kg/667m^(2),an increase of 47.872%compared with the control.Yield had a very significant positive correlation with the number of seeds per plant(P<0.01),and a very significant positive correlation with the number of effective pods per plant(P<0.01).When the Euclidean distance was 5.00,all materials could be divided into 3 groups,namely high-yield,middle-yield and low-yield varieties.【Conclusion】According to the test results,SC15-11,JO14 and Jidou 22 have outstanding comprehensive traits and can be planted for testing in southern Xinjiang.
