Abstract: The carotenoid in sweet potato has a high health value for the human body, and HarvestPlus has also carried out the breeding to improve the nutritional quality of sweet potatoes in order to address the health problems of people nutrient-deficient areas. Nanshu 012 is a new high-quality orange-fleshed sweet potato variety rich in carotenoid, bred by Nanchong Academy of Agricultural Sciences from the "Boga×Sanheshu" hybrid. In the regional test of sweet potato varieties in Sichuan Province during 2009-2010, the average fresh potato yield was 24600 kg/ha, the average dry matter percentage was 29.0% and the average preserved sweet potato yield was 7152.0 kg/ha; in the production test, the average fresh potato yield was 28410.0 kg/ha and the average preserved sweet potato yield was 8734.5 kg/ha. The multi-point sampling analysis showed that the total sugar content of fresh potato was 5.28%, protein content was 1.43%, vitamin C content was 28.9 mg/100g and carotenoid content was 5.21 mg/100g. This variety was identified by Sichuan Crop Variety Approval Committee in March 2012, with high fresh potato yield, sweetness, rich carotenoid and resistance to black spot. It is an orange-fleshed sweet potato variety suitable for eating and food processing, and it should be planted in the plot with moderate fertility or above, and should be planted and harvested as early as possible.
