Abstract
Sixty-five FS taba bean (Viera !aba L.) Egyptian breeding lines. were evaluated for resistance to cowpea aphid. Aphis craccivO(a Koch infestation throughout three successive seasons 1998199 to 200012001 under field conditions. Results showed that the two entries 818/923/92 and 657/1574192 were found to be resistanlltolerant to aphid infestation. in spite of the severe infestation seasons of rabe bear. plantation in Mioele Egypt. 'These two lines also tMded to combine high yielding ability.
Most at the variations in yield components of raba bean varieties was attributable to the size of A. creootvor« infestation. Resistant entries outyielded susceptible varieties and also much less affected by the presence of large numbers of aphids.
