Reacao de hibridos comerciais de milho as ferrugens polissora e tropical. Repositório Alice
PINHO, R.G. von; RAMALHO, M.A.P.; RESENDE, I.C.; SILVA, H.P.; POZAR, G..
Os objetivos deste trabalho foram avaliar o nível de resistência de oito híbridos comerciais de milho aos patógenos Puccinia polysora Underw e Physopella zeae (Mains) Cummins e Ramachar, e comparar a eficiência dos métodos da área abaixo da curva de progresso da doença (AACPD) e dos parâmetros de estabilidade fenotípica, na avaliação dessa resistência. Em quatro ambientes nas regiões Sudeste e Centro-Oeste do Brasil foram realizadas cinco avaliações da severidade das doenças, em intervalos de dez dias a partir dos 60 dias após a semeadura, utilizando uma escala diagramática com notas. Os parâmetros de estabilidade fenotípica estudados foram o coeficiente de regressão linear (b) entre a época de avaliação (x) e a severidade da doença (y) e o coeficiente de...

Reprodução e patogenicidade de Meloidogyne javanica no híbrido EC-2-0 de maracujá-azedo. Infoteca-e
SHARMA, R. D.; RITZINGER, C. H. S. P.; JUNQUEIRA, N. T. V.; ALVES, R; T..
RESUMO: O nematóide formador de galha das raízes, Meloidogyne javanica (Treub) Chitwood constitui-se ameaça para a cultura do maracujá-azedo, Passiflora edulis f. flavicarpa na Região do Cerrado. O híbrido EC-2-0 (cultivar Marília Sul Brasil x Roxo Australiano) tem grande potencial de produção no Cerrado e maior tolerância às doenças da parte aérea. O ensaio foi conduzido em casa de vegetação, na Embrapa Cerrados, Planaltina-DF, visando a determinar a patogenicidade e a reprodução desse nematóide no híbrido EC-2-0 de maracujá-azedo aos diferentes tipos de inóculos: 100, 1000, 10.000 ovos e juvenis de segundo estágio por kg de solo (50% mistura de Latossolo Vermelho Escuro e areia grossa do rio com calagem, adubado e autoclavado) e por planta com 21 dias....

Résistance de la crevette Litopenaeus stylirostris à la bactérie pathogène Vibrio penaeicida : Physiologie, immunologie et pathologie comparées d’une population sélectionnée sur un critère de survie aux épisodes de mortalité et d’une population témoin non sélectionnée. ArchiMer
De Decker, Sophie.
The New-Caledonian shrimp industry is based on the controlled reproduction of the shrimp Litopenaeus stylirostris, a species which was introduced in the 80s. The major difficulty to which the industry has been faced for 10 years is the occurrence of the “Syndrome 93”, which corresponds to mortality phases when the temperature falls down in April-May-June. This mortality is associated to the pathogenic bacteria Vibrio penaecida. An experiment of genetic selection based on the criterion ofsurvival to Syndrome 93 has been conducted at the Laboratory of Aquaculture of New Caledonia. The 3rd selected generation had demonstrated very encouraging results (survival rates improved by around 20% in experimental infections with V. penaeicida). These results have not...

Resistance to OsHV-1 Infection in Crassostrea gigas Larvae ArchiMer
Dégremont, Lionel; Morga, Benjamin; Trancart, Suzanne; Pépin, Jean-francois.
The ostreid herpesvirus(OsHV-1) is one of the major diseases that affect the Pacific oyster Crassostrea gigas. Selective breeding programs were recently shown to improve resistance easily to OsHV-1 infections in spat, juvenile, and adult oysters. Nevertheless, this resistance has never been investigated in larvae, whereas this developmental stage has crucial importance for the production of commercial hatcheries, as well as explaining the abundance of spatfall. A first trial tested several viral suspensions at several concentrations using contaminated water with OsHV-1 in 4- and 10-day-old larvae that we reproduced from an unselected broodstock. In follow up on the results, one viral suspension at a final concentration of 10+6 OsHV-1 DNA copies per L was...
