Data of 81 hybrids with two replications were taken account of, in the municipality of Pasto, Colombia. The results indicated that genotypic correlations were higher than phenotypic and environmental ones. Fruit weight (FW) showed the highest genetic correlations (rG 0.60), with more pulp and seed weight (rG 0 0.90) and equatorial diameter (rG = 0.84). Path analysis based on genotypic correlations showed that internal thickness (EI) was the variable that had the greatest direct effect(1.63) demonstrating that a selection on the basis of fruit weight will result in an increase of the internal thickness. Taking into account the phenotypic correlations, it was established by analysis that the direct effects of equatorial diameter(DE) and polar diameter (DP), (0.30) and (0.26) respectively are the major contributors to fruit weight (PF).</p>}, number={2}, journal={Revista de Ciencias Agrícolas}, author={Duarte A., David Esteban and Lagos B., Tulio Cesar and Lagos S., Liz Katherine}, year={2013}, month={Feb.}, pages={57–80} }
