The number of effective pods is 50.8 of single plant, grain seed number is 2.1 per pod and 100-seed weight is 20.1 g.The protein and fat content is 44.34% and 17.45%, respectively. SC15 and SC18 are resistance to soybean Mosaic virus disease.The yield of Liqiu 3 can reach 2 397.0 kg.ha-1. The new variety expressed the features of high yield and quality, strong disease resistance, barren-tolerance, drought-enduring and waterlogging tolerance, suitable for cultivating in most area of Zhejiang and similar climate region.
