Abstract

The goal of the present work was to evaluate and to select cacao hybrids with respect to seed yield and quality for ecological conditions of municipality of Ouro Preto do Oeste, Rondônia, Brazil. The selection was done comparing, by means of Duncan test, the yield measurement average in trial conducted from 1986 to 1991. A randomized complete block design was used. The best performance, considering total number of collected fruits, total number of healthy fruits, total weight of humid seeds and mean weight of humid seeds per fruit, were obtained from crosses involving POUND 7 and BE 10, SCA 6 and PA 150, PA 150, IMC 67 and POUND 7 clones, respectively. The hybrids SCA 6 x ICS 1, PA 150 x SIC 328 and IMC 67 x BE 8 were outstanding when compared to the others.
