甜玉米杂交种皖甜1号的选育及栽培技术研究

The Breeding and Cultural technique for the Super Sweet Maize Hybrid Wantian NO.1

皖甜1号是安徽省农业科学院作物研究所以自选自交系“皖甜系1号”做母本,外引系“超甜776”为父本育成的超甜玉米杂交种,2004年通过国家农作物品种审定委员会审定。皖甜1号平均鲜穗产量11992.5kg/hm2,比对照穗甜1号增产10.3%。该品种抗逆性强,适应性广,子粒黄色,后期保甜度好,可溶性糖含量达22.4%,且果皮较薄,适口性好,品质较优。该品种适宜在国家东南玉米区种植,具有广阔的开发应用前景。

Super sweet maize hybrid Wantian NO.1 has been accomplished in Crop Institute of Anhui Academy of Agricultural Science, by using self-selections ＆ self-line Wantianxi NO.1 as female parent, foreign self-line Supersweet-776 as male parent. It has been approved and released in 2004 by the Nation Committee of Crop Variety. The average yield of Wantian NO.1 was 11992.5 kg/hm^2 in the regional trials, which increased 10.3% compared with that of check. Wantian NO.1 has the characteristics of wide adaptability, good resistance, and yellow grain. It also has sweetness when picked the ripen ear, water-soluble pdysaccharide （WSP） was more than 22.4%. Furthermore, it has a thinner grain pericarp and good quality. Wantian NO. 1 is adaptable for planting in the areas of southeast China, and has broad prospects for extension and processing utilization.
