Main Article Content
Abstract
This investigation took place in the experimental farm "La Represa", Quevedo, Ecuador. It was determined, the self-compatibility and the morphology of the flower. Its development consisted in the use of a completely randomized DCA design, with forty treatments, and three repetitions. The Tukey test (P?0.05) was applied. Manual pollination tests were carried out, obtaining percentages of 80 and 100% of self-compatibility. Variables of morphology and weight of the flower were registered with statistical differences between the crosses evaluated. These analyzes showed that T1 and T11 were the best in terms of length and width of the sepal. The treatments T10 and T26 in the length and width of the petal. The treatment T20 and T6 for the length of the staminoid and the T10 for the length of the pistil. The weight of the registered flower showed that the T13 and T20, obtained the highest average with 0.065 g, in relation to the other crosses studied.
