Meloidogyne grahami n. sp. is described and illustrated from specimens on tobacco (Nicotiana tabacum) originally from Florence, South Carolina. Considered for several years to be only a race of M. ineognita, this new species readily attacks NC-95 tobacco, a variety with resistance to the M. incognita group that is common in the major U.S. tobacco-producing areas. M. grahami n. sp. is related most closely to the three subspecies of the M. incognita group but differs from all of them, especially… 
Species of root-knot nematodes (Meloidogyne spp.) affecting tobacco in north Queensland, including two new host races of M. arenaria
Thirty-six tobacco crops in the Mareeba-Dimbulah tobaccogrowing region of north Queensland were sampled and 50% of these were infected by root-knot nematodes. These nematodes were identified by
Relationship Between Morphology and Parasitism in Two Populations of Meloidogyne incognita.
It is concluded that there is no relation between perineal pattern, male head shape, and parasitism of host differentials with the two populations studied.
Parasitic Variability of Meloidogyne incognita Populations on Susceptible and Resistant Cotton.
Root gall induction and egg production by the four recognized host races and two cytological races of Meloidogyne incognita were compared on cotton Gossypium hirsutum cvs to find the poorest hosts, who yielded fewer eggs after 45 days than were added initially.
Histopathology of Selected cultivars of Tobacco infected with Meloidogyne species.
Rates of nematode penetration and the histopathology of root infections in fluecured tobacco cultivars 'McNair-944,' 'Speight G-28,' and 'NC-89' with either Meloidogyne arenaria, M. incognita, M.
Oogenesis and the Chromosomes of the Parthenogenetic Root-knot Nematode Meloidogyne incognita
220 popula t ions of Meloidogyne incognita and related forms from 46 countries reproduced by mitotic parthenogenesis (apomixis) revealed the existence of a predominant, possibly triploid race A with 3n = 40 to 46 and a rare, diploidrace B with 2n = 32 to 36 chromosomes.

‘On closer examination the root was found to be covered with excrescences varying from the size of a small pin’s head to that of a little Bean or Nutmeg.’ This observation, from one of the first
