Evaluation of fruit quality onFragaria moupinensis in Tibet
In order to explore fruit quality of wild strawberry in Tibet, wildFragaria moupinensis in Linzhi were chosen as the study materials, and the big fruit strawberries ‘Sweet Charlie’ in the local were chosen as control materials. Single fruit mass, fruit shape index, soluble solid content, soluble sugar content, titration acid content, sugar-acid ratio and vitamin C content were measured and analyzed, and the comprehensive characters were evaluated and analyzed by using projection pursuit technology. The results showed that the phenotype indexes inF. moupinensis fruits were signiifcantly lower than the control (P<0.01,n=30), expect fruit shape index. The quality indexes inF. moupinensisfruits were lower signiifcantly than the control (P<0.01,n=5), and the total acid content inF. moupinensisfruit was signiifcantly higher than the control (P<0.01,n=5), but there were no obvious differences between the soluble sugar content and vitamin C content in the two kinds fruits (P>0.05,n=5). The results of PPE model analysis showed, projection values ofF. moupinensis was 1.1804, which was lower than the control (4.098 2). These results indicated that theF. moupinensis fruit was a little acidic, and it tasted better, but its commercial property was poorer, while the control strawberry fruit was more sweet, which had good taste and good commercial property. So quality ofF. moupinensis fruit was limited compared with CK, which could be used as the breeding material forlfavor fruit.
