Crossing Perspectives Farmers and Scientists in Participatory Plant Breeding

Choice of parents , number of crosses , and population size for participatory and classical plant breeding

Variability in breeding programmes for self-fertilised crops is created by crossing, and if the value of the crosses cannot be predicted in advance then this uncertainty means that a strategy of making many crosses is appropriate. However, since there is a limit to the capacity of a breeding programme, the more crosses that are made the smaller the size of each cross (F2 population size or numb...

Path-dependency in plant breeding: challenges facing participatory reforms in the Ethiopian Sorghum Improvement Program

Participatory plant breeding (PPB) seeks to involve farmers more closely in crop improvement in order to improve the impact of breeding efforts. While detailed discussions exist around appropriate methodologies for conducting PPB, little attention has been directed towards analysing breeding institutions. Such an analysis is necessary, both to understand the possible reasons for poor breeding i...
