Fig. 1. A representation of the pedigree relationships and the simple sequence repeat (SSR) bands at two SSR markers near the major southern root-knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood] (Mi) quantitative trait loci (QTL) on Linkage Group O (LG-O) among Mi-resistant and Mi-susceptible cultivars. Note: FC 33243 was found to possess both susceptible and resistant plants. Solid lines indicate a direct parent and progeny relationship and broken lines indicate an indirect parent and progeny relationship. No shading indicates high Mi galls; gray shading indicates low Mi galls, 200-bp band at Satt358, and 238-bp band at Sat_132; and dark shading indicates low Mi galls, 160-bp band at Satt358, and 248-bp band at Sat_132.
