The centralized plant breeding techniques of the green revolution have yielded good results in more favourable agricultural environments. However, most low-resource farmers in marginal areas have not benefited from these varieties. As an alternative to centralized breeding, farmer participatory approaches using Participatory Varietal Selection (PVS) and Participatory Plant Breeding (PPB) can be used. In PPB, farmers are actively involved in the breeding process, from setting goals to selecting variable, early generation material. Moreover, with PVS, farmers are given a wide range of new cultivars to test for themselves in their own fields.
