        Meloidogyne inornata Lordello, 1956

Synonymized with M. incognita by Jepson ,(1987) and Eisenback and Triantaphyllou (1991) based on morphological features.  However, a comprehensive study by Carneiro et al (2008) confirmed the validoty of M. inornata (Subbtin et al.,2021).

 Synonyms:

Meloidogyne incognita inornata (Lordello, 1956)

Review general characteristics of the genus Meloidogyne.

Chromosome number 2n=54-58. The large number, and variability of chromosome number, and the triploid chromosome number, are typical of species reproducing by obligate mitotic parthenogenesis. (Carneira et al., 2008; Subbotin et al., 2021; Triantaphyllou, 1985).
