Field evaluation of promising faba bean, Vicia faba L. genotypes to cowpea aphid, aphis craccivora koch. infestation and yield performance at Kafr El-Sheikh region [electronic resource].

Includes reference.

Two field experiments were conducted at Sakha Agricultural Research Station to evaluate eleven faba bean genotypes compared with the commercial recommended cultivar Sakha 3 for resistance to cowpea aphid, Aphis craccivora Koch. and high yielding ability under two sowing dates during two seasons; 2005/06 and 2006/07. Results revealed that the lines 1561/49212002 and 96/67/02 are considered promising genotypes in early plantation because they exhibit relative resistance to aphid, but with a high yielding potential. On the other hand, the lines 1561/492/2002 and 81/35/02 were suitable to optimum plantation date and/or earty sowing date if there was an urgent need. Also, results of genotypes reactions to aphid Infestation and yield performance proved that the genotypes: 1561/492; 1571/638, 81/35 and 1618/846 were promising for aphid resistance and yielded 2.72% more than the recommended cultivar Sakha 3. Thus, these promising genotypes could be involved in breeding programs as a source of resistance to cowpea aphid, A. craccivora.
