Screening of Bambara groundnut landraces for resistance / tolerance to Meloidogyne incognita race 2
African Plant Protection 10 (1), 35-41
Abstract: Fifty Bambara groundnut landraces from Botswana and South Africa were evaluated for resistance or tolerance to Meloidogyne incognita race 2 in the greenhouse. Eight weeks after inoculation with 5000 M. incognita eggs per plant, the reaction of each landrace to the nematode was determined by assessing gall and egg mass indices. Host suitability was also determined by means of Canto-Saenz's host suitability designations. Based on gall index being equal to or less than the value of 2, and the reproduction factor less than 1, landrace HVA38-3 was resistant, while the rest of the landraces were susceptible to M. incognita . Landraces CLDRE, A 12, and M 4 showed a tendency towards tolerance to the nematode as reflected in significantly higher yields than the other susceptible landraces in the presence of Meloidogyne infection.
