Abstract:
Taking 100 samples collected，introduced，and preserved by the National Forest Institute of Special Animal and Plant Sciences of CAAS-Jianan Branch as the test materials，multivariate statistical methods including correlation analysis and principal component analysis were employed.Eleven physiological quality indicators of mature fruits，including fruit shape，skin color，soluble solids，total sugars，and total phenol were examined to reveal quality variations among different Actinidia arguta germplasm resources and select high-quality resources based on the established fruit evaluation system, in order to provide references for the improvement of Actinidia arguta varieties.The results showed that cylindrical fruit shape was most prevalent among the tested resources，followed by trapezoidal；fruit color was predominantly dark green and green，with a small proportion exhibiting light red and light green hues.F010202 exhibited the highest transverse diameter，C040803 had the largest longitudinal diameter and highest total sugar content，A010802 showed the greatest lateral diameter，A051402 possessed the highest single-fruit weight，C040803 contained the most soluble solids，D090902 had the highest titratable acid content，and total phenol content in F010501 were significantly higher than in other Actinidia arguta fruits.Principal component analysis was applied to reduce the dimensionality of the 11 indicators，simplifying them into four principal components with a cumulative contribution rate of 77.918%.Significant variations in quality were observed among different Actinidia arguta germplasm resources.Analysis identified fruit width，fruit length，single fruit weight，soluble solids，titratable acidity，total sugars，total phenol，and total flavonoids as key indicators for comprehensive evaluation of Actinidia arguta quality.Calculations identified C010202，A051402，A010802，B030802，and A050902 as the top five superior germplasm resources.
