Abstract:
There was a demand for disease resistant sweet potatoes for different ecological areas in Fujian.As a result, Fushu 90 was bred by crossing Lanputao and Nanshu 88, which has passed the provincial registrations in2014.The new variety had a growth period of approximately 135-150 days, aplant type suitable for the area, and the heart-shaped green leaves tinted with purple stripes and saw-like edge, the purple stems, and the spindle-shaped tubers with red skin and yellowish flesh that were appealing to the consumers.On average, each individual plant bore 2to 5tubers with a production rate of 41 004.45kg·hm-2, or 10 694.1kg dry matters·hm-2 (i.e., 25.99% dry matters in tuber) and 6 695.85 kg starch·hm-2 (i.e., 16.25%starch content in tuber) .In sensory evaluation, Fushu 90 scored 80.9on taste, and 82.0on appearance.The sweet potatoes had a desirable storage property and high budding rate.It also exhibited a high resistance to fusarium wilt.Thus, Fushu 90 was recommended for promotion in Fujian.
