摘　　要：对44份新入圃的国内甘蔗品种资源经过连续2年(1新1宿)的产量及糖分评价,从中筛选出新宿平均糖分高于15%的材料12个,占总数27.27%,超过对照ROC22(14.64%)的有23个材料,占总数的52.27%;平均产量高于120 t/hm^2的高产种质14个,占总数31.82%,超过对照ROC22(147.04 t/hm^2)的有4个材料,占总数的9.09%;平均含糖量高于17 t/hm^2的高糖材料13个,占总数29.55%,超过对照ROC22(21.82 t/hm^2)的有3个材料,占总数6.82%;这些优异种质资源可用于甘蔗遗传改良。Forty-four domestic sugarcane hybrids were assessed according to the yield and sugar content data of sequent two years （planting and ratoon）. The results showed that there were 12 hybrids with high sugar content （more than 15%）, which account for 27.27% of total hybrids. Twenty-three hybrids which took up 52.27% of all hybrids were more in sugar content than the control variety ROC22 with 14.64% sugar content. 14 hybrids presented well in yield and their mean cane yield was more than 120 t/ha. Yield value of four hybrids was more than 147.04 t/ha of ROC22. Sugar yield of 13 hybrids was more than 17 t/ha, only 3 hybrids were better than 21.82 t/ha of ROC22. The good hybrids could be put in sugarcane breeding programs.
