Abstract

The banana is a tropical fruit of greater economic and social importance in the world; Brazil occupies the second place in the ranking world of major producers, which is produced from North to South, from the coastal strip to central plateau, mostly by small producers with low level of capitalization and technology, which produce fruit of bad quality. The objective of this study was to establish ranges of coefficients of variation for banana plantations, setting ranges for classification in CVs low, medium, high and very high and study the relationships among characters of banana evaluated in two production cycles. In the study of coefficients of variation were made in various research literatures dealing with experimentation with banana plantations. Also analyzing the criterion that must be taken into account for the reduction of error experimental, which is related to variation coefficients for each variable. They were calculated by Pearson correlation coefficients among 16 characters in income and development of Tropical cultivar in two production cycles. Each variable studied showed bands of classification of specific coefficients of variation. The variables diameter of the fruit, false stem ( pseudocaule) diameter, number of bunches and the length of the fruit that had the lowest coefficient of variation. Variables cluster weight, fruit weight and weight of the bunch had the highest coefficient of variation. Overall, there were average correlations, positive and significant among the characters. The correlations between cluster weight and weight of bunches, cluster weight and weight of the second bunch, weight bunch and the second bunch, number of bunches and fruits, plant height and false stem (pseudocaule) circumference, weight of the second bunch and average fruit weight and fruit side diameter showed high correlation values.
