| Abstract: | In this study, 9 avocado lines from Danzhou and Baisha, Hainan, China were selected as the research objects, namely DL-F, FR-1, LY-C, LY-L; RK-1, RK-2, RK-3, RK-4, RK-5. 31 important fruit quality traits, including mineral elements, fatty acid composition, vitamin C, total phenols, and flavonoids, of 9 varieties of avocados were determined. Graphite furnace atomic absorption spectrophotometer was used to determine the mineral content in the fruit. Soxhlet extraction was used to extract the oil in the avocado pulp. The relative contents of fatty acids in the oils and fats were determined by gas chromatography-mass spectrometry, the physicochemical properties of avocado oil were determined according to national standards, vitamin C was determined by high performance liquid chromatography, and important fruit quality indexes such as flavonoids and total phenolics were determined by NaNO2-AlNO3-NaOH method and ferrous tartrate method. Results showed that most of the fruit quality traits of different avocado lines were different. The oils of the nine lines had no significant differences in density and refractive index. The different avocado lines were rich in vitamin C, but there was no difference in its content. The fruits had a relatively high content of mineral elements. Compared with other fruits, the contents of potassium, phosphorus and oleic acid were relatively high, which is an important index for evaluating the nutritional content of avocado fruits. Cluster analysis results showed that when the Euclidean distance was 5, the varieties could be clustered into 4 categories. The first category included RK-2 and RK-3, which had high iodine value and low saponification value. The second category included DL-F, LY-L, FR-1, RK-1 and RK-4, which had higher palmitic acid, saponification value, water content and vitamin C content. The third category was LY-C, which performs well in all indicators. The fourth category was only RK-5, which had poor fruit quality. In summary, in this study, a comprehensive analysis of various quality traits of avocado was conducted in different lines from native Hainan, and several analytical methods may provide references for the systematic evaluation and variety improvement of avocado in Hainan. At the same time, the improvement and breeding of superior avocado cultivars should not only be evaluated for fruit quality, but also be combined with a wide range of indicators including disease resistance, fitness, and abundance of fruit, so that avocado cultivars with strong adaptability and suitable promotion can be screened. |
