Wisconsin Potato and Vegetable Growers Associaiton Conference Proceedings. Paper No. 14. Interpretive Summary: Technical Abstract: Plant diseases present a burden to agriculture through yield losses due to plant stress, costs associated with disease control, and efforts to detect infections and limit disease epidemics. Plant breeders are interested in the identification and incorporation of simply inherited genes that confer robust resistance to diseases. These resistance (R) genes typically encode proteins that function to activate defense responses in the plant. Because populations of plant pathogens are constantly changing and can evolve the ability to overcome or elude resistance, we are continuously in need of new sources of host resistance. In potato we are fortunate to have a readily accessible source of germplasm that includes wild relatives of cultivated potato. Due to their coevolution with pathogens in their native environments, these wild species provide a vast resource of resistance to economically important diseases. This talk will be focused on efforts to utilize germplasm resources for disease resistance screening and how identified germplasm can be used for breeding future generations of disease resistant potato varieties. |
