为探明花生品种选育发展变化趋势,对2020-2023年国家登记的587个花生品种的来源分布、选育方式、产量、品质等相关性状进行统计分析.结果表明,587个花生品种主要来自于华北、华南、长江中下游地区,其中山东和河南两省登记数量占总登记数量的53.83%;选育单位主要为科研院所,占比71.72%;品种选育方式以杂交选育为主.花生平均生育期122.0 d,荚果产量4721.5 kg/hm2,籽仁产量3342.9 kg/hm2,百果重200.7 g,百仁重81.0 g,单株饱果数16.8个;花生荚果产量、籽仁产量随登记时间有呈逐年降低趋势.品质方面,油酸含量变异系数最大,为29.91%,含油量变异系数最小,为6.03%;油酸含量≥75%、含油量≥55%、蛋白含量≥28%的品种分别有215、73、55个.聚类分析在欧式距离为12时将花生品种分为3个类群,可分别作为高产、小粒、早熟材料.
Evolution analysis of main traits of registered peanut varieties in China from 2020 to 2023
In order to explore the development of peanut breeding in China,source distribution,breeding meth-ods,yield,quality and other related characteristics of 587 peanut varieties registered during 2020-2023 were statis-tically analyzed.Results showed that 587 peanut varieties were mainly from North China,South China and the mid-dle-and lower-reaches of the Yangtze River,of which Shandong and Henan provinces accounted for 53.83%of the total,and the breeding units were mainly scientific research institutes,accounting for 71.72%.The main breeding method was hybridization.The average growth period of peanut was 122.0 d;pod and seed yields were 4721.5 kg/hm2 and 3342.9 kg/hm2 respectively;100-pod weight and 100-seed weight were 200.7 g and 81.0 g respectively;the full Pod per plant was 16.8;pod yield,seed yield and full Pod per plant decreased by years with the registration time.In terms of quality,coefficient of variation of oleic acid content(29.91%)was the largest,and oil content(6.03%)was the smallest.There were 215,73 and 55 varieties with oleic acid content≥75%,oil content≥55%and protein content≥28%,respectively.By cluster analysis,peanut varieties were divided into 3 groups:high yield,small grain and early maturity with the Euclidean distance as 12.
