To screen big-seed and high-oleic-acid peanut varieties suitable for regional extension in Kaifeng,Henan,nine peanut accessions were selected as experimental materials from the 2023-2024 specialized demonstration trial of big-seed and high-oleic-acid peanut varieties organized by the National Agricultural Technology Extension and Service Center.A total of 12 key agronomic traits and 3 quality indicators were determined,and the entropy-weight coupled DTOPSIS method and grey situation decision-making approach were employed to conduct an objective and comprehensive evaluation on the tested varieties,so as to provide a scientific rationale for the rational deployment and promotion of local peanut varieties.Variation analysis of the experimental materials revealed that the coefficients of variation(CV)of total branch number and pod number per plant both surpassed 10％,and the oleic acid content exhibited the minimum coefficient of variation,with a value of 0.96％.Moreover,weigh-ting results demonstrated that these two agronomic traits also exhibited the highest weight coefficients,reaching 0.370,3 and 0.105,7,respectively.Comparative assessment of the two evaluation systems indicated that the varietal ranking trends showed high consistency and strong reliability,with an extremely significant positive correlation between the two sets of ranking results(R2=0.955,0).The evaluation results of the two methods were essentially consistent:Yuhua155,Zhongyuhua116 and Huayu9118 ranked as the top three in terms of both Ci and ri,j values,and thus are recommended as priority varieties for extension and cultivation in peanut-growing regions of Kaifeng.
