摘　　要：桂糖36(原名:桂糖03-1403,亲系:ROC23×CP84-1198)中至中大茎,发芽出苗好,分蘖能力特强,发株率高,早生快发,前、中期生长快,后期生长势优,特早熟、特高糖、高产、宿根性好、极易脱叶或自动脱叶,适应于中等水肥条件栽培。甘蔗蔗糖分15.58%,较对照种新台糖22(14.44%)增1.14%;产蔗量86.64 t/hm2,与新台糖22(88.29 t/hm2)相近;含糖量13.52t/hm2,较新台糖22(12.71t/hm2)增加6.37%。The sugarcane variety GT36 （ROC23xCP84-1198） was characterized by middle to mid-large stalk diameter,strong tillering vigor,high stoolling capacity,early germination and fast emergence. It showed fast growth in prophase and metaphase,and growth advantage at late stage. It also showed the characteristics of early maturing,high yield of cane and sugar,good ratooning ability,easy or automatic defoliation. The cultivation condition was suitable under medium water and fertilizer. The mean sucrose contents was 15.58% ,increased by 1.14% in comparison with check variety ROC22 （14.44%）; cane yield was 86.64 t/ha,nearly check variety ROC22 （88.29 t/ha）; sugar yield was 13.52 t/ha,increased by 6.37% in comparison with check variety ROC22 （12.71 t/ha）.
