Abstract

High-oleic peanut, known for its superior nutritional quality and health benefits, occupies an important position in the peanut industry; however, its yield is markedly influenced by fluctuations in meteorological conditions, with significant differences among varieties. To systematically elucidate the response patterns of high-oleic peanut to meteorological factors and evaluate yield stability, multi-year field experiments were conducted in representative peanut-producing regions, integrating meteorological data on temperature, precipitation, and solar radiation during key growth stages. Through correlation analysis, stability parameter estimation, and comprehensive adaptability index evaluation, the study identified the sensitivity types of different varieties to major meteorological factors and their interannual yield stability differences. The results showed that high-oleic peanut varieties exhibited significant variation in responses to temperature, rainfall, and light conditions, and varieties with lower meteorological sensitivity demonstrated higher yield stability and adaptability under variable environments. This study clarified the response characteristics and stability mechanisms of high-oleic peanut to key meteorological factors, providing a scientific basis for targeted breeding, regional adaptability evaluation, and climate risk management, and offering theoretical support for the sustainable development of the high-oleic peanut industry.
