摘　　要：赣南02-70是桂糖69-435×CP84-1198的后代,通过有性杂交育种方法,采用五圃制进行选育。10年的研究结果表明,赣南02-70是一个特早熟高产高糖的甘蔗新品种,其农艺性状和工艺性状均表现优良。在省内区试中,公顷蔗茎产量达106200 kg,比对照(赣蔗18号,下同)的90896 kg增产16.84%;蔗糖分达15.05%,高于对照0.42%(绝对值);公顷含糖量达15980 kg,比对照增糖20.15%;且改良了赣蔗18号难脱叶的性状,可降低收获成本,提高甘蔗生产效率,增加农民收入。Gannan 02-70 is the descendant of GT69-435xCP84-1198. It is bred from sexual hybridization with five-plot method during a period of 10 years. The results showed that it is an early maturing, high yielding variety with high sucrose content. Its overall performance is good in both agronomic and technical characters. In the provincial regional test, the cane yield per hectare is 106200 kg, 16.84% higher than that of Ganzhe 18; the sucrose content is 15.05%, 0.42% （absolute value） higher than that of check variety; the sugar content per hectare is 15980 kg, 20.15% higher than that of check. It is easily defoliated which can reduce harvest cost, increase production profit and farmers income.
