Resumen
Descripción
The goal of the present study was to obtain and evaluate inter specific hybrids among P. guajava x P. guineense to be used as guava rootstock or identified F2 plants resistant to the nematode. Susceptible guava mother plant GUA161-PE and tolerant plants ARA138-RR and ARA153-BA, established at an experimental field station in 2008, Petrolina, PE, were used to obtain inter specific hybrids. Guava mother bud flowers presenting petals rupture were emasculated in the anthesis and used for pollinization. The pollinated flowers were protected with plastic bags for 15 days.
