Kainong 705 was a new peanut variety with high yield and large pod which was bred through the sexual hybridization and pedigree selection with Yuhua 9331 as the male parent and Kainong 49 as the female parent by Kaifeng Academy of Agriculture and Forestry. In order to analyze the high yield, stability and adaptability performance of Kainong 705, GGE biplot based on Genstat was applied to identify the pod yield data of peanut regional trials from 2015 to 2016 in north China. The results showed that the average pod yield of Kainong 705 ranked first and yield stability ranked second. The average yield was as high as 5,584.66 kg/ha, which was 11.98% higher than that of the control, and it had better adaptability. The variety was middle resistant to peanut black spot, stem rot, bacterial wilt and rust. The weight of 100-pod and 100-seed were 259.41 g and 104.14 g, respectively. The kernel percent was 70.72%. In conclusion, Kainong 705 was an ideal new peanut variety which had high and stable yield, concentrated pod and strong comprehensive resistance. It was authorized by the Ministry of Agriculture and Rural Affairs of the People’s Republic of China in 2017 and it was suitable for spring sowing and wheat interplanting cultivation in peanut planting areas such as Henan, Shandong and Hebei.
