dc.description.abstractDirect damage caused by aphids by sucking plant sap and indirect damage caused by transmitting many viral diseases are serious havocs in cowpea. The constitutes a formidable obstacle in realisation of its yield potential, unless protected with insecticides. This is turn, leads to high cost of production, serious health hazards and atmospheric pollution . In this contest host plant resistance appears to hold great hope for cowpea production. Experiments on "Genetics of resistance to aphids (Aphis craccivora Koch) and utility of line mixtures in cowpea (Vigna unguiculata L. Walp)" were carried out during 1986-1990 at Department of Olericulture, Kerala Agricultural University at Vellanikkara to isolate cowpea line(s) resistant to aphids, to study mechanism of resistance, Inheritance of resistance and to develop physical mixtures to manage aphids. Three resistant and six moderately resistant lines were identified. The resistant lines are Vs 350, Vs 438 and Vs 452. The moderately resistant lines are Vs 350, Vs 438 and Vs 452. The moderately resistant lines are Vs 306, Vs 307, Vs 147, Vs 456, Vs 457 and Vs 458.en_US
