Polinização seletiva em maracujazeiro amarelo (Passiflora edulis f. flavicarpa) monitorada por vetores canônicos

Abstract

This research was aiemd at evaluating the influence of the relactive pollination of pollen donor plant in obtaition higher fruits of yellow passion (Passiflora edulis f. falvicarpa). To do so, an experiment was conduced according to the controlled crosses, using 23 male plants and 103 pollen receptor plants. The total of fruits obtained was 185 units, that were evaluated according to the following traits: fruit weight, fruit diameter, fruit length, fruit seed number and relative weight of 100 seeds. The data were analyzed by using multivariate analysis (MANOVA). The discriminant function was constituted by the first canonic variable based on matrix of square sum of male (relative importance = 58.1). The discriminant function analysis permitted to verify high effect of male in relation to fruit traits, whose individuals were grouped in three distinct classes. The results indicate that female as well as male can influence the results obtained in mass selection.
