Abstract:

To solve the problem of high quality protein forage,the local variety (Glycine max Merr.) of heilongjiang province had been investigated since 1998 and the new variety of Glycine max Merr. ‘Songnen’ passed the national examination and approval of grass varieties authorized committee in 2013. The results showed that the average hay yield of the new variety was 11985.1 kg·hm^-2 and increased 13.6% compared with control. The seed yield of the new variety was 2088.2 kg·hm^-2 and no significant difference compared to that of control. However, the new variety had high protein content. Therefore, the new variety is excellent legume forage grass and suitable for planting in northern area.

摘要：

为解决优质蛋白饲草缺乏的问题,1998年起对黑龙江省地方品种秣食豆(Glycine max Merr.)进行了整理、栽培研究,选育出松嫩秣食豆(Glycine max Merr.‘Songnen’)新品种,2013年通过全国草品种审定委员会审定。研究结果表明,其平均干草产量为11985.1 kg·hm^-2,比对照品种增产13.6%;种子产量为2088.2 kg·hm^-2,与对照品种差异不显著;蛋白含量高,是优良的豆科饲草品种,适宜在北方地区推广种植。
