Abstract
The objective of this work was to study the degree of association between characters related to head shape quality and productivity of artichoke for in natura consumption.
The experiment was performed at the Universidade de Passo Fundo, Passo Fundo, Rio Grande do Sul State, South Brazil.
Three clones (with six replicates each) of the genotypes Green Globe, Improved Green Globe and Romanesque were evaluated independently for comparison of correlation patterns of agronomical important characters.
Thirteen characteristics related with head shape quality and productivity were considered.
The experiment was conducted in completely random design.
The Pearson correlation coefficient (r) was estimated by the statistic program GENES. It was observed that yield is mainly correlated with fresh mass of the primary head, fresh mass of the receptacle, shape of the primary head, number of total heads at the end of harvest and fresh mass of heads by plant, in the three genotypes.
Significant positive correlations were also found between length and width of the bract base, thickness of the bract base and thickness of the receptacle, head diameter and thickness of the receptacle, head shape and thickness of the receptacle, diameter and length of the primary head, and diameter and fresh mass of primary head.
The primary head shape presented significant correlation with fresh mass, length and diameter of the primary head.
Other important positive correlations were observed between thickness of the receptacle and fresh mass of the receptacle, length and diameter of the primary head, thickness of the bract base and fresh mass and length of the primary head.
It was concluded that there is association among the characters related with shape quality and productivity in the genotypes evaluated, allowing the use of some traits as a selection criteria for breeding of artichoke for in natura consumption.
