A high-yielding cultivar, Robut 33-1, was identified in field tests as having 50-90% lower BND incidence than the commonly grown cultivar TMV 2. The resistance is passive; i.e., when Robut 33-1 plants are infected either by sap inoculation or by infective thrips, they develop normal symptoms of BN D. Robut 33-1 plants did not adversely affect the longevity and fecundity of F. schultzei; however, in field tests, thrips infestation was lower on Robut 33-1 than on TMV 2. This indicates a nonpreference of thrips for cultivar Robut 33-1, resulting in low incidence of BND. 1985 Article PeerReviewed application/pdf en http://oar.icrisat.org/1426/1/Plant_Disease_69_8_718-719_1985.pdf Amin, P W (1985) Apparent resistance of groundnut cultivar Robut 33-1 to bud necrosis disease.
