NUNES, Elaíne Welk Lopes Pereira et al. New sources of resistance to Myrothecium roridum and Podosphaeria xanthii in yellow melon. Crop Breed. Appl. Biotechnol. [online]. 2015, vol.15, n.3, pp.181-186. ISSN 1518-7853.  http://dx.doi.org/10.1590/1984-70332015v15n3n31.

The aim of this study was to identify sources of resistance toMyrothecium roridumand Podosphaeria xanthii.Initially, 86 inbred lines of the crossing AM-04 x Goldex, 91 inbred lines of the crossing AM-12 x Rochedo, and 75 inbred lines of the crossing ACP x AF-646 were evaluated. The trials were carried out in a greenhouse in a randomized block design with five replications. Seventeen inbred lines were identified as resistant to M. roridum.These inbred lines, as well as the parents and seven differential cultivars (checks) were evaluated for the reaction to P. xanthii.Ten inbred lines were selected as moderately resistant to M. roridumand resistant to P. xanthii.
