Exploitation of genetic diversity through participatory plant breeding
Author(s): Bhawana Sharma and Mangla Parikh
Abstract: Agrobiodiversity is the substrate of plant improvement. Genetic diversity remains extremely important not only to individual farmers and farming communities but also to scientists and breeding institutions and humanity as a whole. With the advancement of green revolution, locally adopted populations from the farmers’ field have been replaced with few modern varieties leads towards uniformity. These products have been effective for farming systems sufficiently similar to those on experiment station but not adopted when genotype by environment interactions (GEI) is large. Participatory plant breeding (PPB) is extremely advantageous in those geographic areas where conventional breeding efforts have been less successful and failed to leave a positive impact on farmers’ conditions. PPB is an approach to overcome the limitations of conventional breeding by offering farmers the possibility to select, in their own environment, which varieties suit better their needs and conditions. PPB exploits the potential gains of breeding for specific adaptation through decentralized selection and is the ultimate conceptual consequence of a positive interpretation of genotype x environment interactions. PPB can be resorted to for multiple uses like increasing productivity, preserving diversity and benefits for specific end-users. In order to be a sustainable approach to plant breeding, PPB needs to become a permanent feature of plant breeding programmes, addressing crops grown in agriculturally difficult and climatically challenging environments.
