Descripción

Hybrid Rice is an alternative to create genotypic combinations more productive than the actual varieties. The main factors limiting the heterosis exploitation to Hybrid Rice production are the self-polinization habit of the specie and the difficulty in to test all the possible crosses. The objective of the work was to verify the existence of correlation between genetic distance of parental lines with phenotypic traits and heterosis in F1 hybrids, to predict the potential yield of new hybrid combinations.
