08-20 is a new pea line, was hybridized with Qingying 1 as the female parent and Baofeng 5 as the male parent. It was systematically selected and bred. In the multi-site regional test in Baiyin area, the average yield was 4 822.2 kg/hm2, which was 24.04% higher than that of the control Zhongwan 6. The growth period was about 105 d, the plant height was moderate, the grain was green, and the weight of 100 grains was 23.0 g. The grains contained crude protein was 212 g/kg, crude fat was 13.5 g/kg, crude starch was 508 g/kg and lysine was 12.6 g/kg. The disease plant rate and disease index of powdery mildew in the field were 3.82% and 0.71, respectively.
