Abstract

Abstract:

This study utilized 40 fruiting‘Jinfeng’kiwifruit seedling accessions as test materials，the resistance to bacterial canker was evaluated by artificial inoculation of detached shoots with the pathogen，and the resistance to soft rot was evaluated by artificial inoculation of detached fruits with the pathogen. Simultaneously，nine indicators including fruit shape index，soluble solids content，dry matter content，vitamin C content，and sugar-acid content were measured to analyze and evaluate fruit quality. Based on the length of canker lesions on shoots and the diameter of soft rot lesions on fruits，the 40‘Jinfeng’kiwifruit seedling accessions were classified into 4 levels：resistant，tolerant，susceptible，and highly susceptible. Among them，11 accessions were resistant to canker，17 were tolerant，7 were susceptible，and 5 were highly susceptible. For soft rot，13 accessions were resistant，14 were tolerant，9 were susceptible，and 4 were highly susceptible. Five accessions exhibited resistance to both canker and soft rot. Correlation analysis revealed significant correlations between resistance to fruit soft rot and 3 key quality indicators：soluble solids content，dry matter content，and soluble sugar content. After establishing a comprehensive fruit quality evaluation model using principal component analysis and factor analysis，the fruit quality of the 40‘Jinfeng’seedling accessions was ranked. The top 5 accessions，in order，were 4-266，8-396，2-112，1-77，and 5-325. Combining the resistance performance to canker and soft rot of the top five ranked accessions，three accessions（4-266，2-112，1-77）were ultimately selected as highly disease-resistant and high-quality germplasm.

Key words: kiwifruit, bacterial canker, soft rot, germplasm resources, resistance evaluation, fruit quality
