Abstract

To determine the genetics of resistance to Phytophthora parasitica in Jamaica, the generational means of five resistant and five susceptible lines were analyzed to estimate the genetic parameters of resistance in Jamaica crosses. The analysis showed that the additive effects were more important than dominance effects for resistance to P. parasitica. Heritability, broadly speaking, was 37%. The results obtained indicate that a pedigree program can be effective and the most appropriate to increase genetic resistance to P. parasitica.
