鲜食甜玉米引种筛选试验初报

Preliminary Report on Introduction and Screening of Fresh Sweet Maizes

为筛选出适合福建省种植的高产优质鲜食甜玉米,以粤甜16为对照,于2021年春季对10个鲜食甜玉米进行引种筛选试验。结果表明,供试甜玉米新品种的产量、品质和综合抗性差异较大,其中金冠218和广良甜27综合性状表现优良,株型为紧凑型或半紧凑型,果穗为筒型,籽粒排列整齐,蒸煮后食味优,抗逆性强;产量分别为20331.25、20037.50 kg/hm^(2),分别较对照品种粤甜16增产8.0%、6.4%,可作为鲜食甜玉米优良品种在福建省推广种植。鄂甜玉3号和珍珠牛奶的早熟、珍珠牛奶的低穗位等特性可以作为优质资源供育种利用。

In order to select the high-yield and high-quality fresh sweet corns suitable for planting in Fujian Province,the introduction and screening trial using 10 imported fresh sweet maizes was carried out in the spring of 2021 with Yuetian 16 as the control.The results showed that the introduced new maize varieties had great differences in yield,quality and comprehensive resistance.Among them,the comprehensive characters of Jinguan 218 and Guangliangtian 27 were excellent,they possessed characters of compact or semi compact plant type,tubular type(shape of ear),evenly distributed kernel setting,ideal flavor after processing(steamed or boiled)and good stress resistance.The yield per hectare data of these two varieties were 20331.25 and 20037.50 kg,respectively,which were 8.0%and 6.4%higher than that of the control variety Yuetian 16(yield data 18821.85 kg per hectare),respectively,which could be popularized and planted as excellent varieties of fresh sweet maize in Fujian Province.Other varieties or the traits of them could be considered as germplasm resources for breeding parents,such as the early maturity of Etianyu 3 and Zhenzhuniunai,the low panicle position of Zhenzhuniunai.
