What are the characteristics of the sweet potato variety Xiangfu No. 1?

The Xiangfu No. 1 variety was bred by radiation mutagenesis of F1 hybrid progeny, with Yushu Wang as the female parent and Eshu No. 1 as the male parent.

The stems and vines are short and thick, and the leaves are entire, without lobes, and heart-shaped. The stems branch heavily, the stems and leaves grow vigorously, the tubers set in a concentrated manner, the rate of marketable tubers is high, and each plant sets five or six tubers. The yield of spring sweet potatoes reaches as high as 6 tons per 667 sq m, and in small-scale demonstrations it can reach 10 tons per 667 sq m. In 2006, Feng Shuqing of Xiangtan City planted 9.8 hectares of Xiangfu No. 1 and harvested 735 tons of sweet potatoes, averaging 5 tons per 667 sq m. The heaviest single plant reached 4 kg. On July 20, 22 hectares of autumn sweet potatoes were planted, averaging 4.8 tons per 667 sq m, and the heaviest single plant reached 3 kg.

Fresh tubers contain about 30% starch. In 2001, testing and analysis by China Agricultural University showed starch content as high as 33.1%, with a drying rate of about 45%. It is currently the variety with the highest fresh tuber starch content and drying rate. This variety is tolerant of fertilizer and drought and has broad adaptability, and can be planted in Hunan, Hubei, Jiangxi, Guangdong, Guangxi, Sichuan and other places.
