host is directly related to the host’s resistance ( Taylor and Sasser, 1978 ), the egg mass index and RF were used as key parameters to assess the level of nematode resistance in ‘Datil’, ‘Round of Hungary’, ‘Jalapeño’, and ‘UFRJ107(6)A3’, along with

‘Evangeline’ sweetpotato [ Ipomoea batatas (L.) Lam.] was developed by the Louisiana Agricultural Experiment Station to provide a cultivar with characteristics similar to those of ‘Beauregard’ but with southern root-knot nematode resistance and

increasing economic importance for melon cultivation are nematodes (mainly Meloidogyne ssp.) and the fungus Monosporascus cannonballus , responsible for the melon vine decline disease ( Pivonia et al., 2010 ). Nematode resistance has been described in some

southern root-knot nematode resistance. ‘Bellevue’ is weak in production beds, although adequate plant numbers can be achieved with proper presprouting. ‘Bellevue’ can be harvested up to 10 days earlier than the ‘Covington’ ( Yencho et al., 2008 ) in the
