Resistance to watermelon mosaic virus 1 in derivatives of Cucumis melo L., Plant Introduction (PI) 180280, was found to be controlled by a single dominant gene. The gene symbol Wmv-1 is proposed.
‘Cinco’ is a multidisease resistant muskmelon (cantaloupe), Cucumis melo L., with excellent keeping qualities, good appearance, and delicate sweet taste. It is highly resistant to watermelon mosaic virus 1 (WMV-1); downy mildew, Pseudoperonospora cubensis (Berk. & Curt.) Rostow.; races 1 & 2 of powdery mildew Sphaerotheca fuliginea (Schlect. ex Fr.) Poll.; and Alternaria leaf-blight Alternaria cucumerina (Ellis & Everh.) Elliot. It was developed in south Texas where these fungus diseases occur regularly in epiphytotic proportions. The fruit keeps well for long-distance shipping. The size is that preferred by local market and home garden growers.
Muskmelon (cantaloupe), Cucumis melo L., lines W1, W3, W4, W5, and W6 released by the Southern and Northeastern Regions, Agricultural Research, Science and Education Administration, U.S. Department of Agriculture represent multidisease-resistant advanced breeding lines with high-quality attributes suited to the development of cultivars for long-distance shipping as well as for small farm and home garden production. They were selected under severe epiphytotie conditions in South Texas for resistance to downy mildew, Pseudoperonospora cubensis (Berk.) Rostow.; powdery mildew, Sphaerotheca fuliginea (Schlecht. ex Fr.) Poll.; Alternaria leaf-blight, Alternaria cucumerina (Ell. & Ev.) Elliot; and watermelon mosaic virus 1 (WMV-1). In extensive, replicated, repeated field studies, these lines were consistently found to possess a high level of resistance to all of these diseases, enabling production of a marketable crop under severe disease stress, often without application of fungicides. W4, W5, and W6 exhibit a higher level of resistance to dow ny mildew and Alternaria leaf-blight than do the more moderately resistant W1 and W3 lines. All 5 lines are highly resistant to powdery mildew and have excellent resistance to natural infections of WMV-1.
