Using'Xiangye'as the parent and'Dongyang Hong 1'as the female parent,we investigated and analyzed the performance of strawberry fruit quality in the F1 generation obtained from the cross.We hope to select new strawberry lines with better fruit quality than the parents.In this study,we selected eight F1 generation populations with consistent maturity from 56 groups of F1 generation populations and measured the appearance and intrinsic quality of fruits such as single fruit weight,fruit shape index,soluble protein,soluble solids,soluble sugar,and titratable acid during the fruiting period of strawberries.The results of the study showed that the fruit quality traits of the hybrid progeny of'Xiangye'and'Winter Sun Red No.1'differed significantly from those of the parents,and there were fewer progeny that were better than the parents in various indexes.The smallest variation in morphological traits was in fruit shape index,with a coefficient of variation of 7.5%;the smallest variation in fruit quality was in soluble solids content,with a coefficient of variation of 12.57%;and the largest variation was in titratable acid content,with a coefficient of variation of 32.45%.Through a comprehensive analysis of the fruit traits of the hybrid progeny,21-53 and 21-39 can be used as advantageous strains for strawberry quality improvement.
