摘　　要：为筛选适合云南省德宏州芒市种植的优质鲜食糯玉米品种,本研究于2023年选用德彩糯、瑞糯8号、云糯9号、斯达糯68、斯达糯70和甜蜜糯29共6个鲜食糯玉米新品种,以云南主栽品种石糯2号为对照,在德宏州农业科学研究所试验基地开展了田间品种比较试验,通过生育期、农艺性状、抗病性、鲜穗产量、品质评分等指标对参试品种进行了综合评价。结果表明,参试品种的鲜穗产量为10528.30~14834.08 kg·hm^(-2),均高于对照品种,感官品质和蒸煮品质的总评分在78~88分,全部品种田间均未发生大斑病、白斑病、灰斑病,2个新品种(斯达糯70、甜蜜糯29)有锈病发生,其他品种未发生锈病。相对于其他品种,新品种德彩糯和云糯9号生育期适中,株型半紧凑,长锥穗型,籽多粒重,田间整齐度好,农艺性状稳定,抗病性强,丰产性好,食味品质优,适合进一步在芒市地区进行示范推广种植。To select high-quality fresh waxy maize varieties suitable for planting in Mangshi of Dehong Prefecture of Yunnan Province,the new varieties of fresh waxy maize Decainuo,Ruinuo 8,Yunnuo 9,Sidanuo 68,Sidanuo 70 and Tianminuo 29 were selected to conduct field experiment through the comprehensive evaluation of growth period,agronomic traits,disease resistance,fresh ear yield,quality scores,and other indicators in comparison of main cultivation variety Shinuo 2(control)in the experimental base of Dehong Agricultural Science Research Institute in 2023.The results showed that fresh ear yield(10528.30-14834.08 kg·hm^(-2))of tested varieties were higher than that of control,and the total score of sensory quality and cooking quality was 78-88.All tested varieties did not occur leaf spot disease,small spot disease and grey spot disease in the field,but there were two new varieties(Sidanuo 70,Tianminuo 29)occurred rust disease,while other varieties did not occur rust disease.Compared with other varieties,the new varieties Decainuo and Yunnuo 9 showed moderate growth period,semi-compact plant type,long conical ear shape,more grains number,high grain-weight,good field uniformity,stable agronomic traits,strong disease resistance,obvious high yield ability,excellent cooking quality,which are suitable for further test and promotion in Mangshi Area.
