摘　　要：为加快甘蔗品种改良进程,选育适合湛江旱坡地蔗区种植的优良甘蔗新品种,湛江市农业科学研究院对从台湾引进的甘蔗新品系(暂命名为湛选0617)进行种性研究。经2009—2012年4年14点次新植宿根试验,该品种表现为早熟、高糖、丰产、农艺性状优良、抗逆性强,新宿平均蔗茎产量102 405 kg/hm^(2)、含糖量15 885 kg/hm^(2)、11月至次年1月平均蔗糖分15.52%,分别较对照ROC22增产蔗21.2%、增产糖25.2%、蔗糖分提高0.51%(绝对值,下同)。其中,新植8点次平均蔗茎产量107 730 kg/hm^(2)、含糖量16 695 kg/hm^(2),11月至次年1月平均蔗糖分15.49%,分别较对照ROC22增产蔗12.60%、增产糖16.30%、蔗糖分提高0.49%;宿根6点次平均蔗茎产量95 295 kg/hm^(2)、含糖量14 820 kg/hm^(2)、11月至次年1月平均蔗糖分15.56%,分别较对照ROC22增产蔗36.90%、增产糖41.50%、蔗糖分提高0.52%。该品种适宜广东、广西、云南、海南等省(区)中等或中等以上肥力的旱坡地或水旱地种植,宜保留1~2年宿根。In order to speed up the improvement of sugarcane varieties and select excellent sugarcane varieties that suitable for planting in dry slope sugarcane areas of Zhanjiang,Zhanjiang Academy of Agricultural Sciences conducted a character study on a new sugarcane line (tentatively named Zhanxuan 0617) introduced from Taiwan.According to the new planting and ratoon test at 14 points in four years from 2009 to 2012,this variety showed early maturity,high sugar,high yield,excellent agronomic characters and strong stress resistance.The average cane yield of Zhanxuan 0617 in new planting and ratoon was102 405 kg·hm^(2),the sugar content was 15 885 kg·hm^(2),and the average sucrose content from November to January was15.52%,which was 21.2%,25.2%and 0.51%higher than those of the control ROC22 respectively (absolute value,the same below).Among them,the average cane yield,sugar content and sucrose content of newly planted 8 spots were107 730 kg·hm^(2),16 695 kg·hm^(2)and 15.49%(from November to January),which increased by 12.60%,16.30%and 0.49%respectively,compared with the control ROC22.The average cane yield,sugar content and sucrose content of the ratoon at 6points were 95 295 kg·hm^(2),14 820 kg·hm^(2)and 15.56%(from November to January),which were 36.9%,41.50%and 0.52%higher than those of the control ROC22,respectively.This variety was suitable for planting in dry slope land or flood and dry land with medium or above fertilizer fertility in Guangdong,Guangxi,Yunnan,Hainan and other provinces (regions),and it was suitable to retain its ratoon for 1-2 years.
