Fruit Quality Characters of Various Mango Germplasms
Thirteen fruit quali ty characters(soluble solids content, titratable acidity, carotenoid, fructose, glucose,sucrose, total sugar, total phenolic, antioxidant capacity, K, Ca, Mg, Fe) of 33 accessions of mango germplasm,preserved in South Subtropical Crops Research Institute, Chinese Academy of Tropical Agricultural Sciences,China, were studied. Variance, correlation and principal component analysis(PCA)were used to evaluate the experimental results. The results showed that the wide variation were among the fruit quality characters of mango with variation efficient of 16.05%-70.24%, the largest coefficient of variation was sucrose while the smallest was iron. Significant correlations were found among the quality attributes, but more quality characters were relatively independent. Principal component analysis suggested that thirteen quality characters could be simplified to six principal components, and their accumulative contribution ration amounted to 86.63%. Glucose, fructose, total phenolic, antioxidant capacity, Ca, Fe, K, Mg were the main characters, which could be used to analize mango fruit quality.
