Conteúdo: | The objective of this work was to characterize and identify among the passion fruit hybrids of the second generation backcross (BC2: BC1 × P. edulis), resistance to passion fruit woodiness disease (CABMV) with desirable agronomic attributes. Ninety?two progeny of BC2 hybrids were evaluated for severity of the virus in conditions of field, physical and chemical characterization of the fruits and precocity of the plant in relation to the vegetative and reproductive phases. The data were analysed using multivariate statistics and mixed models (REML/BLUP) to estimate genetic parameters. The urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0001 was conditioned by urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0002 and urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0003, for number of fruits, fruit and peel weight and soluble solids and the effect of urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0004 for virus severity to CABMV and effect of urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0005 on the variables fruit length, fruit diameter, peel thickness and pulp weight. For the titratable acidity it had no urn:x-wiley:01799541:media:pbr12888:pbr12888-math-0006. The progeny BC2?A, BC2?C, BC2?E, BC2?F and BC2?H families can be selected for use in passion fruit breeding programmes by adding high vegetative vigour, early fruit production, resistance to CABMV and also desirable agronomic attributes.
