Potato (Solanum tuberosum L.) is the fourth most important food crop in the world and the largest vegetable crop produced in the United States. Cultivars currently used in production are autotetraploid (2n = 4x = 48). While diploid potatoes (2n = 2x = 24) exist in the wild, they are not often used other than to integrate traits, such as disease resistance, into tetraploid cultivars. Breeding potatoes at the tetraploid level is difficult due to extreme heterozygosity and autotetrasomic inheritance which occurs during sexual reproduction. Reduction in ploidy from the tetraploid to diploid level would induce disomic inheritance, which is genetically simplified compared to tetrasomic inheritance. For this project, haploid inducer line IVP101 has been employed to produce potato diploids using NDSU cultivar, Dakota Trailblazer, and self-pollinated Dakota Trailblazer lines. The experiment evaluates diploid induction rate of IVP101 in Dakota Trailblazer and several S1 Trailblazer lines. An induction rate of 5.6% was obtained from pollinating Trailblazer with IVP101, while varying rates of induction were found in Dakota Trailblazer S1 lines, mostly due to low seed and berry set resulting from fewer flowers produced on the S1s. Successful diploid lines will be evaluated based on tuber yield, viability and robustness of the plant, pollen viability (self-compatibility and outcrossing abilities), and tuber quality. Utilization of diploid potatoes for research could greatly impact crop improvement, simplify breeding pipelines, and allow incorporation of a hybrid production scheme, while use of tetraploids may still be more useful for production.
