Host status of melon, carrot, and Meloidogyne incognita-susceptible and -resistant cotton, cowpea, pepper, and tomato for M. floridensis from California

Average (n=5 for each crop cultivar - Meloidogyne isolate combination) root-galling index (0–10 = no galling – 100% of root system with galls; ±standard error) on roots of different plant cultivars 8 weeks after inoculation with 10,000 eggs/plant of a California isolate of M_ incognita race 3 (Minc-3) or M_ floridensis (Mflor) in two repeated greenhouse pot experiments_
