[1] Taitian 1 is the latest super sweet corn variety introduced from Taiwan Province Province by Beijing Fengyile Company. The main characteristics of this variety are high yield, disease resistance, fertilizer resistance, lodging resistance, short and strong plants, vigorous growth, wide adaptability, large ears, good shape, high sweetness, thin skin, good palatability and good quality. Plant height 182- 193 cm, ear position 57-64 cm, ear length 19.5CM, ear diameter 4.5-4.8 cm, and grain number per ear 5 15. The fresh weight per ear is 283-285g, the first-class ear rate is 7 1%, the grain is golden, and the soluble sugar is as high as 17.7%-2 1.2%. The above quantitative characters, disease resistance, lodging resistance and quality are better than the control varieties. After several years of regional tests, the plants are short and tidy, with dark green leaves, strong growth potential, good adaptability, disease resistance and lodging resistance, long functional period of leaves in the later stage, good green retention, thick panicle length, good yield, high seed sweetness, thin peel, good palatability and good quality. Under better conditions, the yield of green shoots per 667M2 is 900- 1200, which can be as high as 1500 in Yunnan, and good social and economic benefits have been achieved. The disadvantage is that if the flowering period is slightly longer, it can be overcome by auxiliary pollination and strengthening water and fertilizer measures in the middle and late stage.

Taitian 1 has been demonstrated and promoted in Guangdong, Guangxi, Guizhou, Yunnan, Hunan, Hainan and other places, with good response and popularity.

Super sweet corn hybrid is a new super sweet corn variety selected by China sweet waxy corn experts. In recent years, the results of experiments and demonstrations in various places show that this variety ranks at the leading level in China in terms of stress resistance, yield and quality, and ranks first in the national sweet corn regional test for two consecutive years. It is the first choice for canned vegetables, fruits or grains.

The living stems are mature and have good green retention. High lodging resistance.

Its main characteristics are: 1, good appearance quality, full and smooth color, thin skin and easy slag melting. 2. Rich nutrition, high sweetness and good palatability. Tested by the Grain Testing Center of the Ministry of Agriculture, it contains 17 amino acids, accounting for 3.17% of the total weight; The total sugar content on dry basis is 33.4%, and the vitamin C content is 1 15.4mg/ kg. The content of vitamin E is 2.44 mg/kg; At the same time, it is rich in various trace elements necessary for human body. 3.

The water content of "super sweet fruit corn" seeds is within 13%, the germination rate is above 85%, and the sowing amount per mu is 1.5- 1.75 kg. The seedling density is 2800-3000 plants per mu. Planting should be isolated from ordinary corn. Water and fertilizer management should be strengthened in cultivation to control underground pests and corn borer.

The best harvest period of fresh fruit ear of "super sweet corn" is 20-25 days after spinning.
