Estimates of phenotypic, genotypic and environment correlations among seven morphological and agricultural traits in eight pumpkin access

Seven morphological and agricultural traits were analysed in eight access of pumpkin (Cucurbita maxima Duchesne). They were subjected to a phenotypic, genotypic and environment correlations analysis. The genotypic estimates showed botter correlation results than the phenotypic and environmental estimates. Also indicated a moderated influence by the environment in the trait expression. All pairs of traits showed positive genotypic correlation (>0.75) with evidences that the selection aims the increase of traits average, and also it leads to an alteration in the average of the other traits in the same amount. The RAMA F traits (the lenght of the stem until the first female flower) and RAMA T (the lenght of the stem until the top) showed the highest genotypic correlation, while the minor magnitude in this correlation occurred between NS F (number of nodes in the stem until the first female flower) and COMP T (the median lenght of stem's internodes until the top).
