| ABSTRACT: Over several past centuries, specific plant populations have been carefully selected to filter strains with higher agronomic performance. Genetic variability is most essential for successful selection. The Passiflora genus offers great inter- and intra-specific variability. This study aimed to evaluate the physical characteristics of the genotypes of the elite passion fruit (Passiflora alata) for selection purpose. We considered the physical traits of fruit mass, longitudinal and equatorial diameters, peel thickness and color, and pulp mass and volume without and with seeds and pulp yield. The sources of variation for the analysis of variance included the fruits of 8 elite genotypes, with 3 replications, whose means were compared by Tukey’s test... |

| This study aimed to characterize the genetic variability in commercial accessions of passion fruit from the Federal District, Brazil, by RAPD markers. Genetic analyses were done with leaf samples of 30 accessions. DNA samples were amplified by RAPD technique, and respective markers converted into a binary matrix, from which the genetic distances between the accessions were estimated. Clustering analyis based on genetic distances allowed to detect a wide range of genetic variabillity among the accessions of sour passion fruit, and to separate them from the two sweet passion fruit. The graphical positioning of 'BRS Ouro Vermelho' confirms its potential to improve the genetic variability of commercial varieties of sour passion fruit. Dispersal of genetic... |

| Avaliou-se o grau de resistência de 36 clones de maracujazeiro obtidos por seleção massal de sete progênies de híbridos interespecíficos a três isolados de Xanthomonas axonopodis pv. passiflorae. As progênies foram obtidas por meio de cruzamentos entre a cultivar comercial Passiflora edulis "flavicarpa" com as espécies silvestres P. caerulea, P. edulis "roxo" e P. setacea. Os isolados da bactéria foram obtidos em Rio Claro-SP, Planaltina-DF e Limeira-SP. Clones individuais foram inoculados com solução bacteriana na concentração de 108ufc ml-1 aos 120 dias da semeadura. As avaliações ocorreram aos 5, 10 e 15 dias após a inoculação, medindo-se o diâmetro longitudinal e transversal das lesões. Em seguida, calculou-se a área abaixo da curva de progresso da... |
