Global Plan of Action

Activity 10.
Increasing genetic enhancement and base-broadening efforts

168. Assessment: Broadening the genetic base of crops can contribute to increasing stability and performance in crops. However, from the perspective of any individual breeder, company or institute, the costs of incorporating new and diverse germplasm into already adapted material may outweigh the benefits they could realise. Such benefits are often realised only in the long-term and accrue to society in general as well as to other plant breeders. Due to the nature of many genetic enhancement and general pre-breeding activities, international collaboration and public support are warranted.

169. Approaches to genetic enhancement include:

(a) introgression of useful agronomic traits identified through characterization or evaluation into locally adapted or elite material for further use in breeding programmes

(b) base-broadening of breeders material through incorporation of wide genetic diversity.

170. Long-term objectives: To increase food security and improve farmers livelihoods through the development of better plant varieties. To increase the utilization of genetic resources and thereby provide incentives for their conservation. To reduce genetic uniformity in crop varieties through the utilization of wild relatives, local materials and/or modern varieties. To increase sustainability of agricultural systems and the capacity for adaptation to unexpected environmental changes

171. Intermediate objectives: To increase the genetic diversity available in breeders populations through appropriate strategies of introgression (base-broadening).

172. Policy/strategy: Governments, international organizations, non-government organizations and funding sources should recognize the importance of providing long-term funding and logistical support to pre-breeding, genetic enhancement and base-broadening activities.

173. Capacity: Support should be given to national systems, regional networks, International Agricultural Research Centres, non-government organizations, universities and other relevant organizations to carry out pre-breeding and genetic enhancement projects. Priority should be given to addressing problems identified by crop and regional networks, other competent scientific bodies and institutions, and farmers organizations. Initial efforts should focus on the most pressing problems identified in 15 crops of international and regional significance.

174. Research/technology: Institutions, should further develop methodologies for genetic enhancement including pre-breeding, and broadly disseminate these methodologies.

175. Coordination/administration: Activities should be planned and undertaken in close collaboration with national programmes with the collaboration of crop and regional networks, other scientific bodies and institutions, and farmers organizations. Close communication with plant breeders and other scientists in both the public and private sector should be encouraged.

176. This activity is closely linked with:

  • Constructing comprehensive information systems for plant genetic resources for food and agriculture
  • Expanding the characterization, evaluation and number of core collections to facilitate use
  • Supporting on-farm management and improvement of plant genetic resources for food and agriculture.
