A new flat peach cultivar 'Zhongpan 13'

Abstract: 'Zhongpan 13' is an early-mid ripening flat peach, derived from a cross between‘98-2-1'and‘Zhen1-3'in 2007 at experimental field.‘98-2-1', the female parent, is an early-mid ripening yellow peach covered by shining red.‘Zhen1-3', the pollen donation, is flat nectarine and yellow flesh.‘Zhongpan 13'was first selected in 2011 for its large fruit, hard flesh, early-mid ripeness and high yield. It passed the run-off election and named in 2015, licensed by Ministry of Agriculture in 2017, approved by Henan Forest Variety Certification Committee in 2018. Under normal cultivation conditions,the average fruit weight is 180 g, and maximum fruit weight is 260 g. Fruit is mainly flat, and the peel has beautiful color approximately 60% percent of bright red with short fluff. Its flesh is brilliant yellow and firm texture. The peel cannot be peeled, and the core is sticky. The flavor is fragrant and sweet, with a soluble solids content of 12% and a titratable acid content of 0.25%. It is fertile without bringing in pollen donation, and its yield is relatively stable through experiments in Wenxian county of Henan province, Mengyin county of Shandong province and Fengxian county of Jiangsu province. The experiment results also show that under the condition of strictly sparse flowering and fruit, the fruit of this cultivar exhibits large fruits and high soluble solids content, the quality is more excellent. In Zhengzhou, middle China, the first flower of‘Zhongpan 13'comes into bloom mostly appears in late March. Fruits ripen is in late June and early July, about 95 days after blooming. The termination period of fallen leaves is mid-November, and the full growth period is 260 days. Compared with the current main planting variety‘Zhonglintao 11'which is flat peach and yellow flesh matured in mid-to-late July, the fruit mature period of‘Zhongpan 13'is about half a month earlier and the fruit size is smaller. The tree of‘Zhongpan 13'has a strong tree vigor, and attention should be taken to control the tree vigour during cultivation; ridge cultivation can be adopted, with a ridge height of 0.4 m and a ridge width of 1.2 m. It is necessary to properly control the fertilizer and water, and avoid flood irrigation. The fruit setting rate of this variety is very high, and it is necessary to increase the intensity of thinning flowers and fruits. The fruit of this variety is relatively large, the distance between fruits should be greater than 15 cm when thinning flowers and fruits. The appearance of fruit is very beautiful, and it can be cultivated without bags or bagging. However, in areas with heavy rain in the south, there is a phenomenon of cracked fruits,and bagging cultivation is recommended. The bagging time is generally carried out after the fruit is set,when the fruit development enters the stone hardening stage, and the insecticide and fungicide need to be sprayed before the bagging. The fruit has a moderate hardness, which needs to be harvested in a timely manner, and the whole cold chain transportation is better during transportation.
