- Abstract
In order to explore the development of peanut breeding in China, source distribution, breeding methods, yield, quality and other related characteristics of 587 peanut varieties registered during 2020-2023 were statistically analyzed. Results showed that 587 peanut varieties were mainly from North China, South China and the middle- 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.
