【Abstract】 The results of identifying the productivity and essential economic characters of a newly evolved sweetpotato variety named "Yusu 151" are reported. In the regional test in Chongqing from 1999 to 2000, its average weights of fresh tuberous roots, fresh vine yield, fresh tuberous root and vine yield, dry matter yield of tuberous root, dry matter yield of tuberous root and vine are 36.379 t/hm~2, 23.188 t/hm~2, 59.433 t/hm~2, 9.721 t/hm~2, 12.633 t/hm~2 which respectively increased 11.04%, 11.38%, 10.63%, 4.61% and 5.40% comparing with those of "Nanshu 88". Its yields are higher in production than those in regional test. The " Yusu 151" has good bud bursting and early-tuberous-growing, its rate of weight of 100 g tuberous root is over 90%, the content of dry matter is 27.02%, and producing-starch is 13.90% in tuberous root, resisting to black rot and easy storing.更多还原
