Abstract

Screening groundnut breeding lines for resistance to aphids, Aphis craccivora Koch.

Abstract

Some 37 F6 breeding populations were compared with 4 control varieties in a screenhouse study to combine rosette virus [groundnut rosette umbravirus] resistance with resistance to the vector Aphis craccivora. Following artificial infestation, mean aphid populations were recorded 10 and 15 days after infestation. The genotype ICG 12991 had the lowest rate of nymph development, low fecundity and smaller aphids compared with the controls.
