摘　　要：对2006-2012年参加广西糯玉米区域试验并通过审定的糯玉米品种数量、来源、品质、鲜穗产量和抗病鉴定结果进行分析.结果表明：审定的糯玉米品种的品质均未达到1级评分标准,品质中糯性和果皮薄厚指标没有较大突破,多数审定的品种鲜穗产量幅度为10 505～12 000 kg/hm2,鲜穗产量大于12 000 kg/hm2仅在2012年出现.针对广西糯玉米的消费市场和育种水平,糯玉米的育种工作应着重糯性和果皮薄厚及抗病性,兼顾提高鲜穗产量及糯玉米粒色为目标,因此,广西糯玉米品种选育要注重收集和改良种质资源,改进育种方法,以更好地满足市场需要.Variety quantity,origin,quality,fresh ear yield,and resistance to disease of authorized varieties in Guangxi Waxy Maize Regional Trial （GWMRT） from 2006 to 2012 were analyzed.The results showed that the quality of all the authorized varieties didnot reach rank one in grade criterion.Waxy quality and pericarp thickness didnot improve much.The fresh ear yield of most authorized varieties ranged from 10 505 to 12 000 kg/hm2.The yield reached 12 000 kg/hm2 only once in 2012.Acoording to the consumption market and breeding level of waxy maize in Guangxi,the prime objective of breeding work was to improve fresh ear yield and grain color of waxy maize.So we should collect and create new germplasm resources and improve breeding methods to meet the requirements of the market.
