I am working on a wheat breeding project crossing four wheat landraces with an elite wheat cultivar. The aim is to bring the adaptation associated linkage blocks from landraces to elite cultivars. How many adaptive linkage blocks can be carried or what is the accessible number of linkage blocks to incorporate in the elite line? I will do a staged and strategic crossing among landraces and elite cultivars to ensure more linkage blocks are assembled in a single line.
Wheat is highly self pollinated crop. Crossing wheat landraces is cumbersome and needs lots of patience. On field crossing may result in insignificant outcome. Opt for gene pyramiding through molecular techniques, or other methods like incorporating desirable genes with gene gun method. If on field methods is needed,then opt for backcross,then pedigree or bulk method.
It is based on the trait kind you are aiming to transfer. Best is doing backcross and follow up the trait transition by Marker
