大豆新品种在榆林的适应性评价

Adaptability Evaluation of New Soybean Varieties in Yulin

针对榆林地区大豆品种混杂、产业发展迟缓的现状,本研究以9个大豆新品种为试验材料,开展田间适应性鉴定和评价。结果表明,各品种生育期介于141~150 d,均可正常成熟,农艺性状等表现差异较大。综合来看,辽豆69和品豆21两个品种产量表现较为突出,分别较对照增产34.77%和26.95%,且二者裂荚性、倒伏性、抗病性和商品性状等性状均表现较好,适宜在本地区推广种植。

Focus on the current situation of more different soybean varieties and slow industry development in Yulin,nine new soybean varieties were used as experimental materials to identify and evaluate its adaptability in field.The results showed that the growth period of each variety was between 141~150 days,all of which were normally mature,and the performance of agronomic traits was greatly different.Overall,Liaodou 69 and Pindou 21 have outstanding yield performance,with an increase of 34.77%and 26.95%,respectively compared with the control,and their pod cracking,lodging,disease resistance and commodity properties are both good,which are suitable for planting in the area.
