What are the key points for choosing peach varieties for protected cultivation?

The correctness of variety selection is the key to successful protected cultivation. The purpose of protected cultivation of peach trees is to bring them to market early, so when selecting varieties, priority should be given to early-maturing and extremely early-maturing varieties with a short development period. A fruit development period of 60 to 70 days is appropriate, and no more than 80 days. Varieties should also have a short natural dormancy period and a low chilling requirement (cumulative chilling below 7.2°C of less than 850 hours), abundant pollen, a high self-fruitfulness rate, high yield, large fruit, good fruit quality, and tolerance for storage and transport. It is even better if they can adapt to the low-light and high-humidity environment inside the greenhouse. The main varieties include Zaoxialu, Chunlei, Chunhua, Zaohualu, Yuhualu, Annong Shuimi, Xiahui No. 1, Chunfeng, Chunyan, Jingchun, Qingfeng, Mary Vera, Cangfang Zaosheng, and Wuyuexian, etc.; nectarine varieties include Shuguang, Huaguang, Yanguang, Wuyuehuo, Zaohong Baoshi, NJN72, JN76, Armking, Ruiguang No. 1, Ruiguang No. 2, Zaohong No. 2, Zaohongzhu, Danmo, Zaohongxia, and Zaomeiguang, etc.; flat peach varieties include Zaolu Pantao, etc.
