Abstract: ‘Zhongnong Qiuxiang’,a new cold resistant peach cultivar,is derived from the cross between‘Xiongyue Jutao’and‘Okubo’. It has high fruit-setting ratio under natural pollination conditions. The fruit development period is about 136 d. The fruit is round. The average weight of single fruit is 208.5 g. The pericarp is yellow-white. The flesh is yellow and white,and it is semi-free stone. The soluble solids content is 11.2%,the titratable acid content is 0.27%,and the vitamin C content is 98.2 μg • g-1. The yield in the first growth cycle was 11 100 kg • hm-2,and that in the second growth cycle was 28 700 kg • hm-2.
