A breeder is trying to develop a new variety of wheat resistant to a specific fungal pathogen. They have identified a wild relative of wheat that exhibits resistance but has poor yield. Which breeding strategy is MOST likely to introduce the resistance gene into the high-yielding cultivated variety while minimizing the transfer of undesirable traits from the wild relative?
Mass selection
Pedigree analysis
Backcross breeding
Mutation breeding
