Cowpea aphid-borne mosaic virus, Xanthomonas axonopodis pv. passiflorae, Genetic breeding


The use of resistant varieties is a promising strategy for passion fruit woodiness disease (PWD) (Cowpea aphid-borne mosaic virus - CABMV) and bacterial spot (Xanthomonas axonopodis pv. passiflorae - Xap) control in yellow passion fruit (Passiflora edulis Sims). This study aimed at evaluating the reaction of nine genotypes of yellow passion fruit to both mechanically inoculated CABMV and Xap, under protected cultivation. The experiment was conducted using a randomized block design with subdivided parcels comprised of nine treatments, four repetitions, six replications per genotype, and five evaluations. Disease incidence (% plants infected) and severity (% of total leaf area with necrotic lesions or leaf symptoms) were calculated at 7-day intervals. All genotypes evaluated were classified as moderately susceptible to PWD. MAR20#10, MAR20#41, and Rosa Intenso were classified as moderately resistant to bacterial spot whereas the remaining genotypes were classified as moderately susceptible. Genotypes Rosa Intenso, MAR20#41, MAR20#15, and MSCA stood out for presenting the lowest PWD mean severity scores as well as the greatest numbers of plants presenting resistance to PWD after five evaluations. MAR20#10, MAR20#41, and Rosa Intenso demonstrated the lowest bacterial spot mean severity scores. Among the genotypes selected, Rosa Intenso and MAR20#41 were the most promising genotypes for presenting the lowest severity scores for both PWD and bacterial spot disease.
