Introduction and Evaluation of Winter-potato Germplasms

To enrich the resource on potato germplasms for the province, this project introduced 107 germplasms from the Institute of Vegetables and Flowers at the Chinese Academy of Agricultural Sciences in Beijing for evaluation. The morphological characteristics, tuber yield, nutritional quality, dry matter content, low-temperature tolerance, pollen fertility and natural parthenocarpy of 24 of them were scrutinized at test sites in Longhai and Zhouning counties. It was concluded that these germplasms could be used as parents for breeding new winter-potatoes with specific properties.
