Se informa sobre hospedantes, distribución, daños e importancia de Sclerotinia sclerotiorum en la región surpampeana y norpatagónica de la Argentina. Se encontraron infecciones espontáneas en 25 especies vegetales, entre oleaginosas, hortalizas, ornamentales e invasoras. Carduus thoermeri, Xanthium cavanillesii, Marrubium vulgare y Ranunculus repens son hospedantes nuevos de S. sclerotiorum. Los registros en Helianthus tuberosus, Diplotaxis tenuifolia y Cucurbita pepo son nuevos para Argentina. En la región estudiada, S. sclerotiorum causa daños importantes en Helianthus annuus, Glycine max, Apium graveolens, Foeniculum vulgare y Lactuca sativa. Daños menores se observan en Daucus carota, Petroselinum crispum, Brassica oleracea, B. rapa ssp. pekinensis,... |

Weeping lovegrass is well adapted for forage production and useful for soil conservation in semiarid regions, constituting a morphologically diverse group. Diploid genotypes are unfrequent and reproduce sexually, whereas the tetraploids and plants of higher ploidy levels reproduce by apomixis. In the present work RAPD, AFLP and EST-SSR were used in order to assess the reproductive mode through progeny tests, to determine intracultivar homogeneity or seed purity, to establish genetic relationships among the cultivars within the complex and to characterize the new materials obtained by our group. Eight commercial cultivars and three new plant materials were analyzed. Uniform and variable patterns were observed in progenies of apomictic and sexual plants,... |
