Breeding and Cultivation of a New High-quality, Wide-adaptability Purple Sweet Potato, Fushu 24

Aimed to generate a high-yield, strong disease-resistance, wide-adaptability purple sweet potato cultivar, Fushu 24 was bred at the Crop Institute through massive crossing between the female parent, Yanzishu 2, and other resources. The new variety had a fresh-tuber yield of 25 387.26 to 45 314.39 kg·hm^-2, on average a 17.26% increase over that of control, Ningzishu 1. The plant was also highly resistant to the sweet potato fusarium wilt. It was certified by Fujian Provincial Crop Varieties Appraisal Committee and the National Sweet Potato New Varieties Appraisal Committee in 2014.
