摘要:
目的为促进种植业结构调整，满足消费者对糯玉米新品种的需求，通过自交系的创制，选育品质更佳的甜加糯品种供推广种植。
方法 2012年冬，采用自育自交系×外引自交系的杂交模式，组配多个玉米自交系杂交组合；2013年鉴定筛选出若干组合于2014-2015年参加联合多点品比试验，在品比试验中，改01-1b×中zip233表现最佳，于2015年定名为甜糯133。
结果 2016-2017年，甜糯133参加福建省甜糯玉米品种区域试验，2年平均产量15 793.6 kg·hm^-2，比对照品种苏玉糯5号增产22.79%。2018年4月通过福建省农作物品种审定委员会审定（闽审玉20180007）。
结论该品种属中大穗型甜加糯鲜食玉米单交种，具有适应性广、丰产性好、稳产性较高、品质优等特点，适宜在福建省及相似生态区推广种植。
