猕猴桃果实品质及遗传倾向分析
Evaluation of fruit quality and genetic predisposition in kiwifruit
摘要
Abstract
This study utilized eight kiwifruit cultivars as materials to investigate kiwifruit quality traits,including soluble solid content(SSC),soluble sugar content,organic acid content,vitamin C content and aroma components.These traits were analyzed in conjunction with resequencing data.The results indicated that the SSCs of the eight kiwifruit cultivars ranged from 10.90％ to 19.28％,the soluble sugar contents ranged from 80.24 g/kg to 132.82 g/kg,and the organic acid contents ranged from 7.28 g/kg to 30.99 g/kg.Among these kiwifruits,the average single fruit weight of Actinidia chinensis was significantly higher than those of the other species.A.eriantha exhibited the highest vitamin C content,reaching up to 6 541.32 mg/kg.A.arguta had the highest sugar-acid ratio.The main aroma components of A. chinensis,A. deliciosa and A. rufa were esters,whereas the aroma components of A. arguta and A. eriantha were mainly alkenes.The hybrid cultivars 'Jinyan' and 'Mantianhong' also showed esters as their main aroma components.By comparing the quality parameters of the hybrid kiwifruit cultivars with those of their parental species,it was demonstrated that the quality parameters of 'Jinyan' and'Mantianhong' were closer to those of A. chinensis.Genetic clustering analysis also indicated that the two hybrid cultivars were more closely related to their paternal species A. chinensis.关键词
