摘 要:【目的】分析开农系列高油酸花生种质的利用情况,明确其育种价值,阐明其在品种改良中的作用。【方法】以7个开农系列高油酸花生种质及其衍生品种为研究对象,分析衍生品种主要农艺性状变异系数,通过亲缘系数计算7个种质材料的育种贡献值。【结果】截至2024年2月,以7个开农系列高油酸花生种质材料育成的品种一共120个,共被17个科研院校和26个育种企业引用,其中高油酸花生品种105个,占全国育成高油酸花生品种的30.35%;根据优质花生划分标准,高油酸高脂肪品种17个,高油酸高脂肪高蛋白品种1个。对120个衍生品种的12个主要农艺性状分析显示,性状变异系数在4.27%~21.93%之间,其中结果枝数变异系数最高,其次是总分枝数,分别是21.93%和20.81%;变异系数最小的是出仁率,其次是生育期,均小于5%。亲缘系数结果显示,7个高油酸种质育种贡献值总和为58.25,其中以“0317-6”(开农61)育成的品种最多,总育种贡献值最高,分别是44个和21.75,其次是“0317-6A”(开农176),育成的品种和总育种贡献值分别为38和17.75。【结论】7个开农系列高油酸花生种质中,“0317-6”和“0317-6A”被广泛引用,已经成为核心高油酸花生骨干亲本;“0317-15”(开农1715)和“0317-27”(开农71)作为亲本利用也较多,也已成为重要的高油酸花生骨干亲本。【Objective】The objective of this study was to analyze the utilization of high oleic acid peanut germplasms in the Kainong series and to clarify their breeding value and role in variety improvement.【Method】The method involved using seven high-oleic acid peanut germplasms from the Kainong series and their derived varieties as research subjects.The coefficient of variation of the main agronomic traits of the de⁃rived varieties was analyzed,and the breeding contribution values of the seven germplasm materials were cal⁃culated using the kinship coefficient.【Result】The results showed that as of February 2024,a total of 120 varieties had been developed using those seven germplasm materials,which had been utilized by 17 sci⁃entific research institutions and 26 breeding enterprises.Among them,105 varieties were high-oleic pea⁃nut varieties,accounting for 30.35%of the national high-oleic peanut varieties.According to the classifi⁃cation criteria for high-quality peanuts,there were 17 varieties with high oleic acid and high fat content,and one variety with high oleic acid,high fat,and high protein content.The analysis of 12 main agro⁃nomic traits from 120 derived varieties showed that the coefficient of variation ranged from 4.27%to 21.93%,with the highest coefficient of variation in the number of fruiting branches,followed by the total number of branching branches,at 21.93%and 20.81%,respectively.The lowest coefficient of variation was for the shelling percentage,followed by the growth period,both of which were less than 5%.The re⁃sults of the phylogenetic coefficient showed that the total contribution value of the seven high-oleic germ⁃plasms was 58.25,among which,the varieties developed from"0317-6"(Kainong 61)had the highest contribution value,with 44 and 21.75,respectively,followed by"0317-6A"(Kainong 176),with 38 and 17.75,respectively.【Conclusion】In conclusion,among the seven high oleic acid peanut germ⁃plasms of the Kainong series,"0317-6"and"0317-6A"have been widely utilized and ha
