【摘要】 中甜1号是由中国科学院华南植物园与东莞市农业种子研究所合作育成。是以超甜玉米自交系SY203为母本,自交系SW18为父本组配而成的单交种。通过品种比较试验、全省区域试验和生产示范试验,结果表明:中甜1号比目前广东省生产上的主栽品种穗甜1号平均增产8%以上,具有抗大小斑病、青枯病和纹枯病,蚜虫和玉米螟危害轻,抗倒伏以及适应性强等特点。该杂交种植株健壮,生长势强,叶色浓绿,子粒黄白相间,后期保甜度好,可溶性糖含量达18%以上,且果皮较薄,适口性好,品质较优。更多还原

【Abstract】 Zhongtian No.1 is a single cross hybrid which was combined with SY203 as the female parent and SW18 as the male parent. The result showed from the variety comparison experiment Guangdong provincial supersweet maize regional experiment and the production experiments in different regions that Zhongtian No.1 increases the fresh ear yield more than 8% when compared with supersweet maize hybrid Suitian No.1 which is main planting variety in Guangdong corn productinn. Zhongtian No.1 has the character of high resistance to the diseases pests and lodging high comprehensive productivity wide adaptation etc. This new variety has a strong plant a better growth vigour a strong green leave a yellow and white grain. Furthermore it has also a good sweetness when picked the ripen ear. Water-soluble polysaccharoseWSP was more than 18% for Zhongtian No.1 which has a thinner grain pericarp and a good quality.更多还原
