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 was conditioned by and , for number of fruits, fruit and peel weight and soluble solids and the effect of for virus severity to CABMV and effect of on the variables fruit length, fruit diameter, peel thickness and pulp weight. For the titratable acidity it had no . 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.

百香果第二代回交（BC1×西番莲）的农艺表现和对CABMV的抗性的田间评估

这个工作的目的是表征和第二代回交的百香果杂种中识别（BC2：BC1× 毛竹），以具有期望的农学特性西番莲木质病（CABMV）电阻。在田间条件，果实的理化特性，果实的性早熟以及与营养和生殖期有关的植物早熟条件下，对BC2杂种的92个后代进行了病毒严重性评估。使用多元统计和混合模型（REML / BLUP）对数据进行分析，以评估遗传参数。在通过调节和，水果的数目，水果和剥离重量和可溶性固体及效果病毒严重性CABMV和的效果取决于水果长度，果实直径，果皮厚度和果肉重量。对于可滴定的酸度没有。可以选择后代BC2-A，BC2-C，BC2-E，BC2-F和BC2-H来用于百香果育种计划，方法是增加营养活力，早期果实生产，对CABMV的抵抗力以及理想的农艺特性。
