Abstract: ‘Zhongnong Hantao 7’,a new cold resistant peach cultivar,is derived from the cross between‘Xiongyue Jutao’and‘Okubo’. Under the extreme low temperature of–23 to–20 ℃ in Huludao City,it can survive in open field without any cold-proof protection in winter. When the tree has weak growth,its posture will be more open. Its flowers are rose-shaped,and it is capable of fruiting through its own blossoms. The fruit development period is about 110 d. The fruit is round;the average weight of single fruit is 196.0 g. The pericarp is buff;the flesh is yellow and white,and it is freestone. The soluble solids content is 10.9%,the titratable acid content is 0.28%,and the vitamin C content is 76.9 μg • g-1. The yield in the first growth cycle is 12 200 kg • hm-2,and that in the second growth cycle is 31 500 kg • hm-2. It saves labor and effort to manage.
