Performance of Different Varieties of Spring Field Pea (Pisum sativum L.) under Irrigated and Rainfed Environments in North China

Field pea (Pisum sativum L.) is one of the most important pulse crops, and widely grown in North China. To exploit potential varieties suitable for growing spring planting areas, a set National Regional Trials Spring Pea Genotype was carried out under irrigated rainfed environments across seven locations. Grain yield agronomic traits fourteen cultivars were evaluated. Analysis variance indicated that effect genotype, genotypes × interaction significant (p < 0.01). Results GGE biplot analysis showed first second principal components accounted 77.5% 14.5%, respectively. Genotypes just 14.7% variation seed yield, while 39.9%, 45.5% variation. Investigating polygon view led to identification five superior productivity environments. Superior key grain determined using general linear model. The effects inconsistent performance tested Among genotypes, differences observed yield-related traits. semi-leafless variety Longwan 10 highest (3308 kg/ha) over Dingwan 12, 13, Tongwan 5, Kewan 7 higher, stable than overall mean check Zhongwan 6. representative regions field Yondeng, Qitai, Liaoyang, Dingxi Tangshan. These findings represent comprehensive stability locations, which may be useful national international improvement programs.
