Genomic selection for achieving higher genetic gains in groundnut

Led by Irene Breider

Summary

Genomic selection has revolutionised livestock breeding programmes worldwide and promises the same benefits in breeding legume and oilseeds crops, but there are substantial barriers to its adoption, which must first be overcome. These include:

  1. The need for low-cost genotyping technologies to genotype very large numbers of plants to increase selection intensity and training set size in a cost-effective way.
  2. The need to optimally design training populations that will provide suitable genotype and phenotype datasets to derive accurate genomic prediction equations.
  3. The need for well-designed breeding programmes and transition strategies that optimize the use of genomic and existing phenotyping resources, that demonstrate benefits during the transition to genomic selection, and that have manageable costs.

This project will contribute novel solutions to address these barriers to adopting genomic selection in groundnut.
