Results Regarding the Phenotypic Correlations between Quantitative Characters of Interest in Improving Gladiolus Hybrids

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 × b), (b × d ), (a × c) (c × 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.
