“…Devese salientar que estes resultados foram obtidos em área sem histórico de patógenos de solo. Aguiar et al (2017), avaliando os efeitos de diferentes doses de biofertilizantes no município de Nova Floresta, no estado da Paraíba, obtiveram a média de 34,15 frutos por planta, com a variedade Gigante amarelo, resultado inferior aos obtidos neste trabalho quando enxertado em P. gibertii. As diferenças observadas para o número de frutos podem ser explicadas pelo alto índice de mortes de plantas observados nos tratamentos sem enxertia e nos enxertados em P. caerulea e P. gibertii x P. edulis.…”

“…Não há controle químico para essa doença, devendo utilizar-se de práticas culturais e preventivas para o seu controle, tais como: evitar áreas com histórico da doença, evitar o plantio em solos pesados e compactados, utilizar mudas sadias e evitar ferimentos no colo e nas raízes das plantas RESENDE, 2008). Alguns autores tem recomendado o uso da enxertia para o controle dessa doença e algumas espécies como o P. gibertii, P. alata e P. foetida tem apresentado tolerância à murcha de Fusarium (NOGUEIRA FILHO et al, 2010;CAVICHIOLI et al, 2011b;SILVA et al, 2017).…”

The use of tolerant rootstocks has shown good results in the control of Fusarium wilt in yellow passion fruit, which is considered one of the main problems in the crop as it affects the plant’s root system and has no chemical control. The present study aimed to evaluate the survival rates, the agronomic performance of the plants and the physical characteristics of the yellow passion fruit (Passiflora edulis Sims) grafted on different rootstocks in area with Fusarium wilt. The experiment was carried in Pracinha, in the State of São Paulo, Brazil, from August 2014 to May 2015, and a randomized block design was adopted, with five treatments, five replications and four plants per plot. The treatments were constituted by the following rootstocks: Passiflora alata Dryand, Passiflora gibertii N.E. Brown, Passiflora caerulea Linnaeus, double grafting P. gibertii x P. edulis and plants without grafting. The stem diameter of rootstock and the graft, the lenght of secondary branches, the number of tertiary branches, the number of surviving plants, the longitudinal and transversal diameters of the fruits, the number and mass of fruits and the productivity were evaluated. The largest diameter of the rootstock was observed in Passiflora alata while in the graft it was in plants of Passiflora edulis. The length of the secondarty branches and the number of tertiary branches were affected by the type of grafting and the rootstock used. The highest survival rates were observed in Passiflora alata (90%) and Passiflora gibertii (100%). The highest number of fruits per plant and productivity occurred in plants grafted on Passiflora gibertii. The adoption of double grafting using Passiflora gibertii x Passiflora edulis and simple grafting with Passiflora caerulea were not effective in the control of this disease. The species Passiflora gibertii and Passiflora alata showed the potential to be used as a rootstock for yellow passion fruit.

Fusariosis and base rot, caused by the fungi Fusarium oxysporum f. sp. passiflorae and F. solani, respectively, seriously damage the cultivation of sour passion fruit in Brazil. This work aims to obtain and evaluate F1 hybrids of Passiflora spp. wild plants resistant to fusariosis and base rot using genotypes of P. edulis (commercial species) and certify interspecific hybridizations using microsatellite markers. Hybridizations were performed using a P. edulis female parent and P. nitida and P. mucronata male parents for crosses aiming fusariosis resistance, and P. nitida, P. cincinnata and P. quadrangularis for hybridizations aiming tolerance to base rot. 35 microsatellite markers were used to confirm hybridization. The washed roots method was used for fusarium resistance tests and inoculation procedure with a mycelium disk fixed on a small wound on the plant stem for base rot. The interspecific hybridizations provided 49 potentially hybrid genotypes. Confirmation of hybridization by microsatellite marker was verified for 57% of the analyzed genotypes. The hybrids 115-1, 115-3, 115-4, 115-5, 115-6, 115-7, 115-9 and 128 are indicated as promising genotypes for a new stage of the breeding program. In the resistance evaluation of 13 F1 hybrids to F. oxysporum f. sp. passiflorae, the genotypes 142 and 143-2 were selected as the most resistant to continue the breeding program.

“…However, there are still no passion fruit cultivars resistant to collar rot and fusariosis recorded in the Ministry of Livestock and Supply. In this context, knowledge on the pathogenicity and variability of the pathogen population is indispensable for breeding programs aiming the selection of a resistant passion flower cultivar or a hybrid in view of the complex pathosystem, where the pathogen involved presents a genetic variability, as reported by previous studies (Carvalho et al, 2015;Dariva et al, 2015;Silva et al, 2017).…”

This work was carried out with the objective of performing a molecular and aggressiveness characterization of F. solani and F. oxysporum f.sp. passiflorae collected in the Pantanal, Cerrado and Amazon biomes. We selected the most aggressive isolates for use in breeding programs aiming resistance to Collar Rot and Fusariosis. For inoculation of the isolates of F. oxysporum f.sp. passiflorae the washed root method was used. The molecular characterization of the isolates was carried out by partial sequencing of the Transcribed Internal Spacer of the rDNA region. The isolates of F. solani formed two distinct groups in relation to aggressiveness. Among all isolates, FSUNEMAT 40 and FSUNEMAT 46 were the most aggressive. The model with K=2 was taken as the best model to explain the genetic structure of the F. solani populations, with clear combinations of genes from both gene pools. There were three groups with respect to the aggressiveness of the isolates of F. oxysporum f.sp. passiflorae, with the isolated FOUNEMAT 22 being the most aggressive. In view of these results, the isolates of F. solani collected in P. edulis in the state of Mato Grosso presented a high molecular variability independent from the biome of origin, and this was also observed in the tests of aggressiveness. The results indicate the need to consider the molecular variability and the aggressiveness of the pathogens in the evaluation of genotypes of sour passion fruit in programs of selection of resistant cultivars.
