【Main Characters of Varieties】

The average growth period of the two-year regional test was 139 days. The top of the first leaf of the seedlings was round to spoon-shaped, and the color of sheath anthocyanin was medium to strong. The curvature of the leaves is extremely weak to weak, and the angle between the leaves and the stem is small. The coleoptile anthocyanin of the plant has no or very weak color, the plant height is very short to short, and the ear position is short to medium. Early pollen stage, strong color development of anthocyanins except for the base of tassel glume, extremely weak to weak collateral curvature, extremely small to small angle with the main axis, length of main axis above the low side branch of the tassel, and above the high side branch The length of the main axis and the length of the side branches, the number of first-order side branches, the color of anther anthocyanin is medium, the color of filigree anthocyanin is very weak to weak, the stalk of the plant is "Zigzag", the ear stalk is long and tapered The ears, the grains are medium yellow dentate, and the color of cob glume anthocyanins is little or very weak. The average number of ear rows is 20 rows, and the number of rows is 40.4 grains. Quality analysis: bulk density 741g/L, crude protein (dry basis) 7.61%, crude fat (dry basis) 3.58%, crude starch (dry basis) 76.81%, lysine (dry basis) 0.25%.

【Adaptability】

In 2016, the production test average yield was 686.2 kg per mu, an increase of 15.5% compared with the control, and the rate of increase in production was 100%. The sum of lodging and inversion rates is 0.0%, and the percentage of test points where the sum of lodging and inversion rates is ≥10.0% is 0.0%. Resistance identification: high resistance to large spot disease, small group disease, ear rot, Curvularia leaf spot; resistance to gray spot, stem rot, rust, and susceptible sheath blight.

【Main cultivation measures】

1. Sowing seeds at the right time. Seed after the temperature has stabilized and passed 12°C. Sow in mid-to-late April.

2. Make sure to sow the whole seedlings. Improve the quality of soil preparation, sowing 2-3 seeds per hole.

3. Reasonable dense planting. According to the results of the 2012 density test, it is recommended that the field planting density be 4000 to 4200 plants per mu.

4. Strengthen field management. The seedlings grow neatly and grow vigorously. To apply plantar fertilizer, use 50 kg of special compound fertilizer per acre, farm manure over 1,000 kg, and 1 kg of zinc fertilizer, 15 kg of urea per acre in the 5-leaf stage, and 25 kg of urea per acre in the 11-12-leaf stage. Combine topdressing and weeding twice.

5. Pay attention to pests and diseases such as sheath blight. In low-lying land, attention should be paid to clearing ditch and draining water and lowering the groundwater level, which can effectively reduce the occurrence of diseases. Control corn borer during the big bell mouth stage.

[Suitable area for planting]

It is suitable for planting in the corn area of Yunnan Province with an altitude of 2000m-2400m. Spring maize is introduced in mountainous and hilly areas at an altitude of 800 meters and below in the western part of Hubei Province.
