What is the fine-grained topic of the following text: Our research unit mainly works on potato (Solanum tuberosum) for 1) the identification and deployment of under-utilized sources of resistance and quality traits for breeding, and 2) understanding the genetic and molecular basis of autopolyploidization. Only return the topic.
