Repeatability of the production, number and weight of fruit in red mombin (Spondias purpurea L.)

The repeatability allows estimating the number of evaluations or production cycles to select superior genotypes with higher efficiency and lower operating costs. This study estimated coefficient of repeatability of production, number and weight of fruit in 11 red mombin clones, to evaluate the possibility of performing individual phenotypic selection. Were analyzed average data of 5 seasons, from 3 plants per clone, propagated by cuttings. The coefficients were estimated by the methods of analysis of variance, principal components and structural analysis. The principal components method based on the variance and covariance matrices estimated the largest coefficients in all traits. Exception of the estimated coefficient for number of fruits, by the principal components method, all others reached values equal or smaller than 0.38. It is possible to perform individual phenotypic selection between red mombin clones based on the production and number of fruit per plant. The evaluations of 6, 4 and 8 harvests for production, number and weight of fruit allow to select clones with promising about 80% accuracy. The IPA-6 clone produced 17.62 kg of fruits for plant, outperforming other materials evaluated.
