SUMMARY A combined selection of maternal half sib was applied to a local pipiana squash population under the maize-squash association system. Genetic variances for plant, fruit and seed characters were estimated. The results indicate that genetic variance exists for the different characters under study. The total genetic variance was determined mainly by additive effects of the genes. The heritability changed with the cycles of evaluation and selection; in 1997 it fluctuated between 24 and 83 %, and in 1998 between 6 and 90 %. Characters of fruit such as color, thickness and flavor of flesh were improved by selection: color turned from an unpleasant green to a pleasant yellow; the seed enlarged 0.02 cm in width; thickness of flesh gained 0.14 cm, and flavor went from insipid and sour to sweet.
