A field study was conducted to determine the rate of genetic improvement in grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004. Results showed that grain yield ranged from 568 kg/ha for an old variety TVX3236 to 1851 kg/ha for a recently release...

Selection indices provide useful information to breeders who usually base selection on meansand ranks. Knowledge on selection criteria for improving tef grain yield is very limited. Accordingly, theobjective of this study was to develop selection criteria for improving tef grain yield through ind...

Soybean rust, caused by Phakopsora pachyrhizi, has become a threat to soybean production in west, central, east and southern Africa. This foliar disease can cause 40-80% yield loss under African conditions. IITA started to develop resistant lines for this disease since 2003 and a number of homozy...

Tef is a staple cereal of Ethiopia in high demand by consumers. In order to cope up with this high consumer demand, productivity per unit of land must increase through the development and use of high-yielding varieties. To this effect, the National Tef Research Project has long been striving towa...
