Advances in Potato Breeding for Abiotic Stress Tolerance

AbstractPotato is the third important food crop for global food security. To breed new varieties with stress tolerance, tuber yield and quality are a base for sustainable development of the potato industry. With climate and environmental change, the breeding of abiotic stress tolerance potato varieties has become a research hotspot. This paper summarizes the evaluation methods, genetics, and molecular mechanism of potato tolerance to abiotic stress, including salt and alkali, drought, cold, and heavy metal. The progress of transgenic breeding of potato under abiotic stress was introduced. Finally, the prospect of potato abiotic stresses breeding was put forward.KeywordsStress toleranceSalt and alkaliDroughtColdHeavy metal
