Abstract:
Prebreeding programmes facilitate generation of novel populations essential for crop improvement programme besides identification of heterotic patterns needed for development of hybrid populations. One of the key factors which contributed to successful adoption of prebreeding approach is utilization of landrace germplasms, unadapted exotic lines, and wild relatives from the primary, secondary and tertiary genepools. Prebreeding and cultivar development are essential interdependent activities and are the major controlling factors that determine the pace at which cultivars are released consistently to the farmers. This chapter deals with attempts made employing certain prebreeding methods and strategies followed to transfer key genes from wild genepools to cultivated oilseed crops.
