Abstract

To determine the intensity of the relationship between two variables forming a normal dimensional distribution the correlation coefficient (r) was calculated. Using empirical data recorded from the field, direct correlations were performed between four characters ((a Ã— b), (b Ã— d ), (a Ã— c) (c Ã— d)) and were obtained both positive and negative values of the coefficient of correlation having different degrees of signification. The greatest value of the r = 0.91 was founded in variety Early Riser, being distinctly significant. The total height of the plant directly influences the length of inflorescence.
