Identification and comprehensive evaluation of drought resistance in high oleic acid Jihua peanut varieties
摘要
Abstract
Drought is one of the primary limiting factors in the production of high oleic acid peanuts.Identifying drought resis-tance and screening for drought resistance indices in high oleic acid peanut varieties are crucial for breeding drought-resistant cultivars and advancing research on drought resistance mechanisms.In this study,26 high oleic acid peanut varieties of the Jihua series were evaluated for drought tolerance under controlled drought conditions during 2022-2023.At maturity,each variety's nine agronomic indicators,five economic indicators,and quality indicators were determined under both normal irrigation and drought stress treatments.To identify and assess drought resistance,we employed correlation analysis,principal component analysis,membership function analysis,grey relational analysis,stepwise regression analysis,cluster analysis,comprehensive drought resistance evaluation values(D-values),comprehensive drought resistance coefficients(CDC),and weighted drought resistance coefficients(WDC).The results showed that agronomic and economic indicators under drought treatment were reduced by 9.73%-49.19%compared to those under irrigation,while quality traits decreased by 0.78%-9.84%.Significant correlations were observed among the individual drought resistance coefficients(DC)of each index.Eight principal components were able to represent 89.81%of the original information related to drought resistance in high oleic acid peanuts.The drought resistance of high oleic acid peanuts was consistent across D-values,CDC-values,and WDC-values,with D-values showing strong positive correlations with CDC-values and WDC-values(correlation coefficients of 0.885 and 0.913,respectively).Based on D-values,the high oleic acid peanut varieties were categorized into three groups:nine drought-resistant varieties,ten moderately drought-resistant varieties,and seven drought-sensitive varieties.Among the varieties,Jihua 1353 and Jihua 712 exhibited excep-tional drought resistance.Key indicators such as yield,main stem height,pod number per plant,and full pod rate can serve as primary criteria for identifying drought resistance in high oleic acid peanut varieties at maturity.These findings provide a theo-retical foundation and practical guidance for breeding,understanding the mechanisms of,and cultivating drought-resistant high oleic acid peanuts.关键词
