摘要:

甜加糯玉米是我国首创的鲜食玉米新类型,兼具甜玉米和糯玉米的风味优点,口感甜糯相宜,近年来深受市场欢迎,已成为鲜食玉米产业的重点发展方向。温州市农业科学研究院旱粮育种团队自2010年起开展甜加糯玉米种质创新和品种选育,采用异隐纯合体杂交(糯玉米×甜糯玉米)模式,并通过多年田间表型鉴选和籽粒糖度、食用品质等鉴定评价,成功选育出甜加糯玉米温科糯2号。该品种具有高产稳产、配合力强、生育期短、品质优良等特点。于2018—2019年春季参加糯玉米品比试验,于2021—2022年参加东南区鲜食糯玉米联合体区域试验,平均667 m2产量为1 161.15 kg,比对照增产21.61%,并于2023年通过国家审定。本文系统介绍了温科糯2号的选育过程、特征特性及配套栽培技术,以期为该品种的推广提供技术指导。

Abstract:

Sweet-waxy maize is a new type of fresh-eating maize pioneered in China. It combines the flavor advantages of both sweet and waxy maize,offering a sweet and waxy texture,and has gained strong market popularity in recent years,becoming a key development direction in the fresh maize industry. Since 2010,the Dryland Crops Breeding Team of Wenzhou Academy of Agricultural Sciences has been engaged in germplasm innovation and variety breeding of sweet-waxy maize. Using the heterozygous recessive homozygous hybrid method (waxy maize × sweet-waxy maize) and through multi-year field phenotypic selection as well as evaluations of grain sugar content and eating quality,the team successfully bred the sweet-waxy maize cultivar Wenkenuo 2. This cultivar exhibits high and stable yield,strong combining ability,short growth period,and excellent quality. It participated in the spring waxy maize comparative trials from 2018 to 2019,the Southeast China Fresh Waxy Maize Consortium regional trials from 2021 to 2022,achieving an average yield of 1 161.15 kg per 667 m2,a 21.61% increase compared with the control,and obtained national approval in 2023. This paper systematically describes the breeding process,characteristics,and corresponding cultivation techniques of Wenkenuo 2,aiming to provide technical guidance for its future promotion.
