摘　　要：为筛选出适宜在通辽地区种植的优质饲用大豆,以6个野生大豆与栽培大豆杂交后代品种(系)为研究对象,通过对其产量和品质的研究进行生产性能的综合评价。结果表明:饲用大豆的鲜草产量、干草产量、粗蛋白、粗脂肪和粗灰分含量受到收获时期和品种交互作用的影响。以这5个指标为基础,通过主成分分析从中提取出2个主成分,累积贡献率达82.56%。以鲜草产量和粗蛋白含量作为有效评价指标,采用模糊数学隶属函数法对不同时期收获的饲用大豆进行综合评价。评价结果为:饲用大豆的最适收获期为结荚初期,此时生产性能最佳;S001草实兼用杂交野大豆是6个饲用大豆中生产性能最好的品种,适合在通辽地区推广种植。In order to select high-quality forage soybeans suitable for planting in Tongliao,we took 6 varieties(strains)from Glycine soja×Glycine max cross as the research objects.The comprehensive evaluation of its production performance was conducted through the study on the yield and quality.The results showed that the fresh grass yield,hay yield,crude protein,crude fat and crude ash content of forage soybeans were affected by harvest periods and varieties.Two principal components were extracted from the five indexes by principal component analysis,and the cumulative contribution rate reached 82.56%.The fresh grass yield and crude protein content were used as effective evaluation indexes,and the fuzzy mathematical membership function method was used to evaluate forage soybeans harvested at different stages.The evaluation results were as follows:The optimal harvest period of forage soybean was the early pod formation period.Forage soybean S001 was the variety with the best production performance,suitable for planting in Tongliao Area.
