Preliminary Screening of Bag-free Peach Varieties and Their Fruit Coloring Evaluation in Guanzhong Region
Fruit appearance plays a crucial role in market acceptance and is an important determinant of consumer preference.This study analyzed and compared the visual quality of 34 bag-free peach varieties,in-cluding fruit weight,color intensity,and degree of coloration.This study aims to identify the most suitable varie-ties for bag-free cultivation in the Guanzhong region.The results showed that 16 varieties such as'Zhong-taoziyu','Zhongtaofeiyu','Jinlinghualu','Zhongtaojinyang','Lixiahong','Ganluzaoyou','Zijinhong 2','Zijinhong 3',and'Meiting'could be cultivated without bagging.Varieties such as'Baojiahong','Bao-jiajun','Cuibao','Yanbao','Jiuyan','Daifei','Xiahui 8','Jinhua','Jinshuo','Jinfeng',and'Jinchun'had relatively poor appearance when grown without bagging in the Guanzhong area.It is recommen-ded to bag these varieties to improve their commodity value after thinning.Additionally,it advised that flat pea-ches be bagged during production,as the risk of fruit tip cracking higher when they are not bagged.This study will serve as a guide to help reduce farmers'costs,improve bag-free technology,and promote the growth of the Shaanxi peach industry.
