“…phaseoli is not well known; thus, few studies report information on genetic control (Cross et al, 2000;Brick et al, 2004;Pereira et al, 2008;2009c;Cândida et al, 2009;Musoni et al, 2010). Currently, of the common bean cultivars available to growers, few have adequate levels of resistance to Fusarium wilt (Pereira et al, 2011;2016;2018). Thus, efforts should be directed toward obtaining new cultivars resistant to this disease.…”

Fusarium wilt is a serious soil disease affecting common bean cultivation, especially crops under a central pivot irrigation system. Our objective was to identify bean lines that combine resistance to Fusarium wilt in the field with other desirable traits. Twenty-eight randomized block trials with three replicates were conducted in the rainy, winter, and dry seasons from 2009 to 2012 in the states of Goiás, Federal District, and Paraná. The trials were composed of six elite lines (one carioca and five black grain type) selected in a previous study as resistant to Fusarium wilt under controlled conditions and five cultivars (three carioca two black grain type). Variance analysis demonstrated variability for reaction to Fusarium wilt and anthracnose, yield, architecture, and lodging tolerance. The interaction among the lines/cultivars and environments was significant for all traits. Five black bean lines were resistant to Fusarium wilt (grades <3.0) in the field; however, none of these lines outperformed the best controls in other traits, especially anthracnose resistance (grades >4.0). The Carioca line (CNFC 15872) was susceptible to fusarium wilt (5.6). Thus, these lines should not be indicated as suitable cultivars. Cultivars BRS Esplendor and BRS Notável exhibited excellent yield (2144 and 2200 kg.ha -1, D.G. Pereira et al. 2 respectively), high stability, erect architecture (3.4 and 4.1), lodging tolerance (3.3 and 4.0), anthracnose resistance (1.0 and 1.7), and high fusarium wilt resistance (2.0 and 2.6). These cultivars are still excellent options for planting in areas with Fusarium wilt.

“…f. sp. phaseoli Kendrick & Snyder (Fop) is considered one of the main root diseases of common bean and has spread across all bean-producing areas of Brazil (Pereira et al 2011). Decreased yield caused by this disease have been increasing, especially in areas with successive and irrigated crops (Toledo-Souza et al 2012).…”

“…O período de avaliação foi bem reduzido além de propiciar uma boa distinção das plantas resistente. Vários trabalhos realizados com inoculação de F. oxysporum corroboram com a eficiência da metodologia de inoculação por imersão das raízes em suspensão contendo o patógeno por um determinado período (19,22). No entanto, não encontra trabalhos utilizando solução nutritiva para o desenvolvimento das plantas.…”

O maracujazeiro azedo é uma importante fruteira amplamente produzida e consumida no Brasil. A produção e produtividade estão ameaçadas por vários problemas fitossanitários. Uns dos mais importantes é a fusariose, causada pelo fungo Fusarium oxysporum f. sp. passiflorae. Esta doença não tem controle eficiente. Neste sentido o objetivo deste trabalho foi avaliar a resposta de plantas, em estágio de muda, de 14 espécies de Passiflora mediante a inoculação de F. oxysporum f. sp. passiflorae cultivadas em solução nutritiva. As espécies utilizadas no Screening foram: P. quadrangularis, P. nitida, P. foetida, P. tenuifila, P. alata, P. setacea, P. cincinnata, P. mucronata, P. micropetala, P. suberosa Passion fruit is an important fruit vine widely produced and consumed in Brazil. Production and productivity have been threatened by several phytosanitary problems. One of the most important problems is fusariosis, caused by the fungus Fusarium oxysporum f. sp. passiflorae. This disease has no efficient control. Thus, the aim of this study was to evaluate the response of plants of 14 Passiflora species, in the stage of seedling, through inoculation of F. oxysporum f. sp. passiflorae grown in nutritive solution. The species used in the screening were P. quadrangularis, P. nitida, P. foetida, P. tenuifila, P. alata, P. setacea, P. cincinnata, P. mucronata, P. micropetala, P. suberosa, P. morifolia Preisigke, S.C.; Silva, L.P.; Serafim, M.E.; Bruckner, C.H.; Araújo, K.L.; Neves, L.G. Early selection of Passiflora species resistant to fusariosis. Summa Phytopathologica, v.43, n.4, p.321-325, 2017.P. eichleriana P. edulis and P. coccinea. Four seedlings of each genotype were inoculated by immersion of roots in a suspension of 1x10 6 spores mL -1 during 24 hours and then transplanted into pots containing nutritive solution. Plants were daily evaluated during 40 days for the occurrence of wilt symptoms and death. The survival period and the mortality rate were obtained. The method of root immersion for 24 hours and the replacement of soil by nutritive solution were efficient in distinguishing the resistant genotypes. There was intraspecific variability in relation to the disease. The most resistant species were P. foetida, P. mucronata, P. nitida and P. morifolia.O maracujazeiro azedo (Passiflora edulis Sims) é a espécie mais conhecida e estudada dentro do gênero Passiflora. O Brasil, desde a década de 70, vem se destacando como maior consumidor e produtor mundial desta fruteira. Porém, problemas fitossanitários ameaçam o setor produtivo dessa cultura. As doenças causadas por patógenos de solo são as mais preocupantes pois não tem nenhuma forma de controle eficiente. Dentre essas doenças, destaca-se a fusariose ou murcha de Fusarium causada pelo fungo Fusarium oxysporum f. sp. passiflorae (15).O fungo F. oxysporum f. sp. passiflorae coloniza os vasos das plantas através de pequenos ferimentos ou aberturas naturais nas raízes, obstruindo os vasos causando murcha e consequentemente a morte da planta. É uma doença que provoca g...
