【Abstract】 The results of identifying the productivity and essential economic characters of a newly evolved sweetpotato variety named “Yusu 297” are introduced.In the regional test in Sichuan province from 1994 to 1996,its average weights of fresh tuberous roots,fresh vine yield,fresh tuberous root and vine yield,dry matter yield,dry tuberous root and vine yield are 20 18 t/hm 2,24 04 t/hm 2,44 22 t/hm 2,6 20 t/hm 2,9 08 t/hm 2 which respectively increased 0 59%,0 00%,0 26%,5 26% and 3 53% comparing with those of “Nanshu 88” Its fresh tuberous root yield is especially higher than that of “Nanshu 88” in productions in Chongqing and Sichuan.The “Yusu 297” has good bud bursting and easy storing properties,early tuberous growing,the rate of weight of 100 g tuberous root and over in total tuberous root was over 75%,the content of dry matter is 30 74%,and producing starch is 1900%,and amino acid is 241% in fresh tuberous root,resisting to black rot.更多还原
