Abstract
Plant breeding focuses on the genetic enhancement of the plants which is hampering the limited availability of germplasm resources. Pre-breeding, being a multi-disciplinary approach, provides a special opportunity to lessen this genetic vulnerability and develop the new base population for enhanced crops and varieties, by introducing desirable genes from wild germplasm to agronomically suitable backgrounds. It has emphasized on the improvement of the core gene pool of several crops including rice, wheat, barley, chickpea and groundnut. Linkage drag poses a difficulty in pre-breeding that could be reduced using genomic approaches. The major requirements, objectives and approaches have been discussed in the following article.
