摘　　要：以远杂9102与徐州68-4杂交构建的RIL群体为材料,通过连续2年4个生长季节的鉴定评价,筛选出百果重稳定在200 g以上的优良大果材料65份,稳定高于高值亲本材料2份;通过对稳定大果材料的出仁率鉴定,获得了26份大果兼高出仁率材料,其中4份材料的出仁率高于高值亲本。进一步对这26份优良材料进行鉴定,获得了13份大果高出仁率同时株高适中的优良种质。该研究结果对于聚合多个优良性状的优良花生品种的培育具有重要意义。The RIL population from the crossing between Yuanza 9102 and Xuzhou 68-4 was used as materials.Based on the four consecutive growth seasons’identification and evaluation,65 RILs with 100-pod weight higher than 200 g were screened,and 2 of them were stable higher than the high-value parent Xuzhou 68-4.Among the 53 large-podded RILs,26 had high shelling percentage and 4 of them were higher than high-value parent Yuanza 9102.Among the 26 RILs with large pod and high shelling percentage,13 had appropriate plant height as well.These results have great significance for the cultivation of peanut cultivars pyramiding multiple elite traits.
