2. Variety source
Liaoning Tieyan Seed Science and Technology Co., Ltd. was a single cross bred in 2006 with Tie0102 as female parent and Tie0322 as male parent. The female parent is from Mo 17× American pioneer hybrid P07, and the male parent is from Tie98042× Tie7922.
3. Characteristics
The leaf sheath of seedlings is purple, the leaves are green, the leaves are green, and the seedlings are strong. The plant type is semi-compact, the plant height is 290 cm, the ear position is 129 cm and the number of leaves per plant is 2 1. Filaments are light purple, anthers are green and glumes are purple. The panicle is conical, in the middle of the panicle stalk, in the bract leaf, the panicle length is 15.0 cm, the rows per panicle are 12- 18, the panicle axis is red, the grain is orange-red, the grain shape is semi-horse-toothed, the 100-grain weight is 35.7 g, and the seed rate is 84.4%.
According to the agricultural products quality supervision, inspection and testing center of the Ministry of Agriculture (Shenyang), the bulk density of grain is 774.2g/L, the crude protein content is 8.78%, the crude fat content is 3.76%, the crude starch content is 75.88%, and the lysine content is 0.28%.
The growth period of spring-sown maize in Liaoning is about 130 days, which is about 2 days earlier than that of the control Zheng Dan 958, and it belongs to the mid-late maturity maize hybrid.
After artificial inoculation in 20/0/0, 2009, it was found that it was susceptible to leaf spot (1-7), resistant to gray spot (1-3), moderately resistant to Curvularia leaf spot (1-5) and susceptible to stem rot (/kloc)
4. Yield performance: Participated in the regional test of high-density mid-late maturity group of maize in Liaoning Province on October 20, 2009, with an increase of 14 points and a decrease of 2 points. The average yield per mu for two years was 659.5 kg, which was 6.5% higher than that of the control Zheng Dan 958; Participated in the same group production test in 20 10, and the average yield per mu was 6 15.4 kg, which was 1 1.7% higher than that of the control Zheng Dan 958.
5. Key points of cultivation techniques: The suitable density for planting in plots with medium fertility or above is 4000-4500 mu/plant.
6. Suitable areas: Suitable for planting in middle and late-maturing corn areas such as Shenyang, Tieling, Dandong, Fuxin, Anshan, Jinzhou, Chaoyang and Liaoyang. The active accumulated temperature is above 2800℃.
Extended data:
Matters needing attention in planting corn:
1. Choose varieties suitable for the local area, and don't choose seeds across regions, otherwise it will make corn dehydration difficult and affect grain sales.
2. Sow in strict accordance with the planting density indicated by the manufacturer, and don't blindly increase the sowing amount, otherwise it will increase the risk of maize lodging.
3. Planting fertilizer must be isolated by 8- 10 cm, otherwise the root system of corn will be tied to the fertilizer pile when the three leaves are United, causing the fertilizer to burn the root system, making the corn lack the root system and affecting the nutrient absorption.
