Screening of Representative Fruit Quality and Excellent Rosa roxburghii Tratt.Resources
In order to determine the representative fruit quality of Rosa roxburghii Tratt.,screen the excellent breeding parents,improve the single quality of Rosa roxburghii Tratt.,and promote the rational development and application of wild Rosa roxburghii Tratt.resources,55 wild Rosa roxburghii Tratt.and 1 seedless Rosa roxburghii Tratt.were used as test materials,and 25 fruit quality traits like total phenols,total flavonoids,total triterpenes,superoxide dismutase(SOD)and vitamins(Vc)were determined,and the fruit quality and germplasm resources of Rosa roxburghii Tratt.were evaluated comprehensively.The results showed that epicatechin,catechin hydrate and chlorogenic acid were the three main monomer phenols in total phenols.Total phenol,2,2'-hydrazine di(3-ethyl-benzothiazole-6-sulfonic acid)diamiammonium salt(ABTS),iron ion reduction(FRAP),epicatechin,polydatin,gallic acid,Vc,SOD,fruit weight and solid acid ratio could be used as representative indexes of antioxidant capacity,fruit appearance quality and sugar-acid flavor,respectively.The germplasm XY13,ZJ14,QX8,LC7 and GP6 were suitable for breeding the high antioxi-dant capacity of Rosa roxburghii Tratt.varieties.The 10 germplasm resources with the best overall quality were XY13,QX8,GP6,ZJ14,LC7,AL11,AL7,GP3,ZY1 and WC1.
