These germplasm lines (with PI numbers ranging from 550899 to PI550925) were released in 1991 for use as source germplasm or as parental lines in high-rainfall tropical midaltitude regions. They were developed by selfing in the IITA Midaltitude Streak Resistant (TZMSR) and tropical lowland (TZSRW...

Drought is a major constraint to faba bean (Vicia faba L.) production, and there are many mechanisms by which leaves can regulate water loss. Our primary objective was to test if the origin of the faba bean accessions, from drought-prone and non-drought-prone environments, was associated with dif...

A total of 436 African landraces and 497 improved cassava genotypes were planted in 1996, 1997, 1998 and 1999 growing seasons.. These were evaluated for their reactions to cassava anthracnose disease (CAD) under natural infection conditions at Ibadan (a high infection zone). The severity of the d...
