Agronomic performance and yield stability of field pea (Pisum sativum L.) genotypes in multi-environment trials
The selection of stable, high-yielding pea genotypes is crucial for sustaining production under changing climate conditions. Twenty multi-environment trials (10 locations x 2 years) were conducted to evaluate 11 genotypes during the 2020–2021 and 2021–2022 growing seasons in southern China. The Additive Main Effects and Multiplicative Interaction (AMMI) pooled analysis revealed that environmental effects accounted for the largest proportion of total variation (59.62%), followed by genotype-by-environment interaction (GEI) at 30.11%. The factor analysis revealed that plant height, first pod height, number of nodes on the main stem, number of pods/plant, number of seeds/pod, and number of nodes containing pods were the best multi-traits that significantly contributed to high yields. Cluster analysis identified five superior genotypes - Jingwan 8, Yuwan 6, Yunwan 116, 20205, and Suwan 8, with Yunwan 116 also showing disease resistance. The genotype main effects plus GEI (GGE) biplot identified Kunming and Xinxiang locations as the most effective environments for differentiating the genotypes, and Jingwan 8 as the ideal genotype for high yield and stability, particularly in these locations. Further, Yuwan 6 and 20205 also showed wide adaptability across environments. Jingwan 8, Yuwan 6, and 20205 pea genotypes are recommended for large-scale cultivation due to their high yield and broad adaptability.
