Technical Abstract: Root-knot nematode, RKN, (Meloidogyne incognita) is a serious problem for vegetable production in the southeastern US for many Solanaceous crops including peppers, tomatoes and eggplant. The use of alternative methods to methyl bromide includes finding suitable rootstocks for resistance to this nematode in pepper. We conducted studies to evaluate potential resistant rootstocks to RKN. Five resistant rootstocks (Fery and Thies, 1998) ‘Charleston Belle’, ‘Charleston Hot’, ‘Carolina Wonder’, ‘Carolina Cayenne’ and Mississippi Nemaheart were compared to the susceptible varieties ‘Keystone Resistant Giant’, ‘Yolo Wonder B’, ‘PA-136’ and Caribbean Red Habanero. Aristotle was used as the scion for all the above varieties. All of the experiments were conducted under greenhouse conditions. The grafted plants were exposed to M. incognita and rated for nematode damage. Gall ratings were significantly different for the varieties with ‘Caribbean Red Habanero’ having the highest rate of galling by the general liner models procedure (GLM) and mean separation was performed using LSD. The gall ratings from lowest to highest were: ‘Charleston Hot’<’Carolina Cayenne’<’Mississippi Nemaheart’<’Charleston Belle’< ‘Carolina Wonder’<’Keystone Resistant Giant’<’PA136’<’Aristotle non-graft’< ‘Aristotle self-graft’> ‘Caribbean Red Habanero’ >’Yolo Wonder.
