Wang X.D., and Guo T.X., 2025, Effects of continuous rainy weather on pea pod set rate and preventive measures, Legume Genomics and Genetics, 16(6): 297-312 (doi: 10.5376/lgg.2025.16.0030)

Pea is one of the important legume crops in my country, but its pod setting rate is easily affected by environmental conditions. In recent years, continuous rainy weather has occurred frequently in some planting areas, resulting in insufficient light, soil moisture and high incidence of diseases, which have led to the obstruction of pea flowering and pod setting and a decrease in yield. This study focuses on the physiological mechanism of pea pod setting, systematically analyzes the specific effects of continuous rainy weather on the pea pod setting rate, including photosynthetic restriction, root inhibition and pollination and fertilization barriers, compares the response differences of different pea varieties to continuous rain, explores the characteristics of highly sensitive and shade-tolerant varieties and their pod setting rate under rainy conditions, and proposes targeted prevention and control strategies and field management measures on this basis. Through case analysis in Yunnan, Gansu, Guizhou and other places, local experience is summarized and the effectiveness of the above measures is verified. This study provides a scientific basis for coping with the decline in pea pod setting rate under abnormal climatic conditions, and hopes to enhance the risk resistance of pea production.
