Conteúdo: 	Inheritance of resistance to cowpea aphid, Aphis craccivora Koch, in three resistant cultivars of cowpea, Vigna unguiculata (L.) Walp. was studied. The parents, F1 and F2 population were grown in an insect-proof screenhouse. Each 3-day-old seedling was infested with 10 apterous adult aphids. Seedling reaction was recorded when the susceptible check was killed. The segregation data revealed that the resistance of ICVII and TVU310 is governed by single dominant genes. All the F2 seedlings of the cross ICV10xTVU310 were resistant, indicating that they have the same gene for resistance.
