Evaluate two sets of hybrids (30 hybrids developed from ESA and 25 developed from India across agroecologies in Kenya, Tanzania and Sudan
1] 46 Topcross hybrids developed from ESA OPVs and lines from WCA together with three OPV parents were evaluated as a PYT trial at Kiboko. A lattice square design with three replications was used. 2] Twenty one hybrids developed from India and three from ESA were evaluated together with the commonly grown OPV variety ICMV 221 as a check. This was established as a regional hybrid trial at Kiboko, Kenya and Miwaleni, Tanzania using RCBD design with three replications.
