Phylogeography and population structure analysis reveals diversity by mutations in Lasiodiplodia theobromae with distinct sources of selection

Lasiodiplodia theobromae is a plant pathogen with a worldwide distribution, with low host specificity, causing stem cankers, dieback diseases, and fruit rot in several species of plants. In coconut, this pathogen is reported as the etiological agent of “coconut leaf blight” (CLB) disease, causing several losses in fruit production. The CLB is an importan.. Read More»

Efficiency of circulant diallels via mixed models in the selection of papaya genotypes resistant to foliar fungal diseases

    M. Vivas, S.F. Silveira, A.P. Viana, A.T. Amaral Jr., D.L. Cardoso and M.G. Pereira

Diallel crossing methods provide information regarding the performance of genitors between themselves and their hybrid combinations. However, with a large number of parents, the number of hybrid combinations that can be obtained and evaluated become limited. One option regarding the number of parents involved is the adoption of circulant diallels. However, informati.. Read More»

Selecting black-spot resistant papaya genotypes derived from backcrossing and hybrids

    T.P.S. Poltronieri, S.F. Silveira, M. Vivas, R. Santa Catarina,D.F.M. Cortes, A.O.N. Azevedo and M.G. Pereira

Papaya crop is important to Brazilian agribusiness. However, the expansion of papaya cultivation in the country is affected by the absence of commercial cultivars presenting good disease resistance. The black-spot caused by the fungus Asperisporium caricae is the most damaging foliar disease affecting Brazilian papaya crops. The use of genetically resistant cultivar.. Read More»
