BIOMETRICAL AND PHYSICO-CHEMICAL CHARACTERIZATION OF FRUITS OF MANGO 'UBA' ACCESSIONS

This study had as the main objective the evaluation of the genetic dissimilarity in mango 'Uba' accessions in the eastern region of Minas Gerais by means of biometrical and physical-chemical characterization of the fruit in order to identify materials which have industrial interest for breeding studies. Fruits of 67 accessions were characterized by evaluation of fruit mass, endocarp mass, pulp/endocarp ratio, longitudinal diameter, transversal diameter, total soluble solids (TSS), titratable total acidity (TTA), TTS/TTA ratio and pH. The results were evaluated by descriptive statistics using central trend (average) and variability of data (standard deviation). Statistical analyses were performed using the clustering techniques and dissimilarity measures. The fruits which have showed the best characteristics for the processing were the hits from the 10, 22, 23, 24, 35, 38, 40, 42, 52, 55 and 63. Cluster analysis demonstrated the formation of two groups of accesses in reference with the biometrical and the physical-chemical characterization of the fruit, which shows the genetic variability the eastern Minas Gerais' mango.
