NEGREIROS, Jacson Rondinelli da Silva et al. Physicochemical characteristics of fruits of progenies of yellow passion fruit tree half-sib in Rio Branco - Acre. Rev. Bras. Frutic. [online]. 2008, vol.30, n.2, pp. 431-437. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452008000200028.
The present study aimed to evaluate and to characterize 39 progenies of half-sib of yellow passion fruit tree to subsidize the program of genetic breeding of this culture. The experimental design was carried out in randomized blocks, with 39 treatments (39 progenies of half-sibs), with 2 replications and 5 plants per plot. The evaluations were done in the second year of production. The evaluated characteristics were: length and diameter of the fruit, relation of length/diameter, mass of the fruit, of the skin and of the pulp, yield of pulp (arils + seeds), thickness of the skin, titratable acidity (TA), soluble solid content (SS) and SS/TA relation. On the basis of the physicochemical characteristics of the fruits, it was possible to make a characterization of the 39 progenies of the evaluated half-sibs. The fruits of progenies 3, 27 and 39 present desirable characteristics for the in natura market, while the progenies 9, 10, 16, 17, 32 and 38 have important characteristics for the processing.
