摘　　要：为筛选适宜重庆市推广种植的弹性鲜收糯玉米品种,选取重庆市大面积种植及近年育成糯玉米品种开展春播、夏播田间试验,分别进行产量测定、不同采收时期鲜穗蒸煮品质评分和适采期天数比较分析。结果表明:春播和夏播条件下,参试品种产量、不同采收期鲜穗蒸煮品质评分以及适采期天数存在显著差异;不同播期条件下,‘玉糯918’产量较对照‘渝糯7号’显著减产,其余品种较对照无显著差异或显著减产‘;达糯19’、‘科大糯4号’、‘珍糯521’、‘彩甜糯900’、‘科大糯2号’适采期天数均优于其他品种。通过产量、不同采收期蒸煮品质评分和适采期天数比较‘,科大糯2号’、‘珍糯521’两品种在不同采收期蒸煮品质和适采期天数均显著优于对照,且比对照增产,可作为重庆市弹性鲜收糯玉米推广种植。In order to screen the elastic fresh-harvested waxy corn varieties suitable for popularization and planting in Chongqing,waxy corn varieties planted in Chongqing and bred in recent years were chosen for field experiments on spring and summer sowing,and yield,cooking quality score of fresh spikes at different harvest periods,and optimum harvesting period days were compared and analyzed.The results revealed that there were significant differences in the yield of the tested varieties,cooking quality scores of fresh panicles at different harvesting times,and optimum harvesting period days under spring and summer sowing conditions.Under different sowing dates,the yield of‘Yunuo 918’was significantly lower than‘Yunuo 7’,and there was no significant difference or significant yield reduction in other varieties compared with‘Yunuo 7’,‘Danuo 19’,‘Kedanuo 4’,‘Zhennuo 521’,‘Caitiannuo 900’,and‘Kedanuo 2’had better optimum harvesting period days than other varieties.By comparing yield,cooking quality scores of different harvesting time and optimum harvesting period days,‘Kedanuo 2’and‘Zhennuo 521’were significantly better than the control in cooking quality and optimum harvesting period days,and the yield was higher than the control,which could be used for waxy corn promotion and planting in Chongqing.
