2. Introduction of Hua Fu 970 maize seed.
1, growth cycle
The average whole growth period of Hua Fu 970 regional trial was 126. 1 day, which was 9.7 days later than Haihe 2.
2. Plant characteristics
(1) The anthocyanin in the first leaf of the seedling is very strong, and the top is round to spoon-shaped. The angle between the upper leaf and the stem is small, and the angle between the lower leaf and the stem is small. The bending degree of blades is weak. Terrier? What? The degree of glyph is not or very weak, which supports the color development of root anthocyanins. In terms of leaf width and greenness, the color of anthocyanins in leaf sheath is zero or extremely weak. In spike high school, the plant height is moderately high, and the ratio of spike height to plant height is moderate.
(2) The anthocyanin color at the base of the spikelet glume is not or extremely light, the anthocyanin color in the glume is extremely light except the base, the anthocyanin color in the anther is extremely light to light, the spikelet density is sparse, the angle between the lateral branches and the main axis is large, the bending degree of the lateral branches is weak to medium, the length of the main axis above the lowest lateral branch of the spikelet is medium-long, and the number of the middle and first lateral branches above the highest lateral branch is medium-small and medium-short. The color development of anthocyanins in the filament of female ear is very weak to weak.
(3) The panicle stalk is extremely short, medium in length, thick in diameter, medium in rows per panicle, conical to barrel-shaped, the grain is dentate, the main color at the top is medium yellow, the main color at the back is medium yellow, the grain is nearly wedge-shaped, and the anthocyanins on the panicle axis are colorless or extremely weak.
3. Inoculation identification
Moderately resistant to gray leaf spot, rust, ear rot, susceptible to big leaf spot and sheath blight.
4. Quality inspection
The bulk density is 778g/L, and the content of crude starch (dry basis) is 75.6%, crude protein (dry basis) is 9.5%, and crude fat (dry basis) is 5.45%.
5. Output performance
(1) 20 18-2019 participated in the trial of Yunnan jade corn experimental consortium: the average yield per mu in the regional trial of 2018 was 809.9 kg, which was 20. 1% higher than that of Haihe No.2, and the yield increase was very significant, with the point rate/kloc. In 20 19, the average yield per mu was 760.6 kg, which was 17.2% higher than that of the control. The yield increase effect is very remarkable, and the yield increase rate is 100%. The two-year average total growth period of the regional trial was 126. 1 day, with an average yield of 785.2 kg per mu, which was 18.7% higher than that of the control Haihe No.2, and the yield increase rate was 100%.
(2) In 2019, the average yield per mu was 755.5 kg, which was 18.4% higher than Haihe No.2, and the yield increased by 100%. The sum of lodging and lodging rate is 0, and the test point of the sum of lodging and lodging rate is 0.
6. Suitable areas
It is suitable for planting in maize areas with altitude of1000-2000m in Yunnan Province.
