Abstract:

‘Zhongnong Hantao 1’is a new mid-early maturing and cold resistance peach cultivar. Its parent is the seven-year-old eminent naturally seedling tree collected from the countryside garden in Taoxian Town of Shenyang. The peach fruit is suborbicular，its flesh is pink and its pericap is thin，with white bottom colour and bright red sunward side. The average weight of the fruit is 288 g，the maximum weight can be up to 366 g and the edible rate is about 95%. The total soluble soilds content is 11.3%，titratable acid content is 0.56%，vitamin C content is 6.21 μg · g^-1. The fruit behaves well on the point of making juice for its high juice yield，about 73.5%，and the strong anti-oxidation character of its rosy juice. The new cultivar has the character of earlier bearing and stable harvesting，and its yield is 37.5 t · hm^-2 in the fourth year of engraftment. Additionally，the new cultivar has high cold resistance，but is not anti-waterlogging or tolerant for saline-alkaline，so it is suitable for cultivation in Huludao of Liaoning and similar zone. After many years of field observation，the peach tree is resistant to gummosis and scab and should be prevented from brown spot perforation.
