Suppоse yоu hаve identified а new pаthоgen that causes a different kind of leaf rust on peanut. In growing a sample of the peanut PI (plant introduction) collection, you identified one out of 100 PIs that seem to have near immunity to this disease. In a preliminary cross of this PI with your best cultivar, the F 1 was nearly immune. However, this PI has very poor agronomic characteristics. Do you think this would be a situation where the backcross breeding method rather than methods like pedigree breeding should be used? Why or Why not? If the F1 was susceptible to leaf rust would your answer change (and why)?
