Effects Of Pollen From Different Peach Varieties On Fruit Setting Rate And Fruit Quality Of Hongfenguang Peach

Hongfenghuang peach fruit is big,good flavor,resistant to storage and other characteristics,but in recent years found Hongfenghuang peach pollen quantity is insufficient,since the flower fruit rate and other issues,affecting its yield and economic benefits,need to choose the appropriate pollination varieties.In this study,six varieties of Zaojinyu,Shantao,Qinwang,Jinyu,Okubo and Chaoyue were selected as polluted varieties in the Dumacun Demonstration Park in Pinglu County,Yuncheng County,Shanxi Province.The results showed that the lowest fruit yield was 36.27%and the highest was Jinyu and Qinwang,and the fruit setting rate was 50.51%and 46.67%respectively.The fruit quality test showed that the average fruit quality of the six pollinated varieties was Qinwang and Jinyu,respectively,275g and 249.17g,the highest soluble solids content for the Qinwang and Shantao,respectively,12%and 11.75%,vitamin C content of early Jinyu and Okubo,respectively 6.19mg/100g and 6.11 mg/100g,fruit surface color index for the transcendence and early Jinyu,respectively,31.99 and 30.85.The results of SPSS statistical software were used to analyze the principal component analysis and system clustering.Based on the rationality-satisfaction and multivariate value theory,the results showed that the combination of Qinwang and Hongfenghuang pollination,early Jinyu and Hongfenghuang pollination combination is suitable for pollination combination of Hongfenghuang peach.
