Collaborative project: Methodological Foundations of Diploid Hybrid Potato Breeding - subproject C (ZucKar)
Project
Project code: 281D116C21
Contract period: 01.01.2023

The overall objective of this project is the creation of methodological foundations to optimize breeding for diploid hybrid potato varieties ("DHP"). The transition from traditional breeding of tetraploid clonal varieties towards diploid, true-potato seed (TPS)-based varieties offers several quantitative genetical and methodological advantages, which promise a higher selection gain and a faster adaption of new varieties, in particular to changing climatic conditions. A central problem of DHP breeding is currently inbreeding depression, which limits the success rates for the development of inbred lines, the parents of hybrids. The main objective of this project is the development of a strategy to overcome inbreeding depression of diploid potato in an efficient way. Moreover, the test-cross hybrid testing scheme shall be optimized to maximize overall selection gain.
