Abstract: Prunus sibirica‘Shanxing 4’is a new cultivar of Siberian apricot selected from the wild population in Zhalantun City,Inner Mongolia through initial selection,reselection,and final selection(natural selection). This cultivar has excellent characteristics such as frost resistance,high and stable yield,bitter kernels,and strong adaptability. During the full fruit stage,the average apricot stone yield(≥ 8 years old)is 2 130 kg · hm-2. Under natural frost conditions(-2 ℃),the pistil frost damage rate is 1.28%,with a post-frost fruit set rate of 72.98%. This cultivar is suitable for large-scale promotion and application in semi-arid regions with similar ecological conditions to Chaoyang and Fuxin City in Liaoning Province.
