Joint research 17 corn seeds are genetically modified? Now the corn is genetically modified!

I didn't find this variety, I don't know which company developed it! In fact, each variety has a range of suitable planting, maybe it is high yield in Henan, but not in Hunan!

Haven't started planting this year? Now it is the peak period of seed selection, I planted Tieyan 53 last year, the performance is okay, this year I have added, I hope the sky can be good, in order to have a good harvest.

The variety of maize seed with high yield is L2.

Introduction of Dragon High L2:

The high-yield corn variety Longgao L2 is known for its yield per mu of tons of grain (667), iron stalk resistance and high water and fertilizer conditions, Longgao L2 has created a high-yield record of 32,000 catties per hectare, which is praised by the industry.

Corn seed Longgao L2 was bred by the High Yield Breeding Room of Maize Research Institute of Heilongjiang Academy of Agricultural Sciences, and was approved by Heilongjiang Provincial Variety Examination and Approval Committee in 2004. The approved name of the variety is Longgao L2, and the trade name is Baoyu Longgao L2.

This corn variety is suitable for a wide area, the growth period is about l22-l27 days, the approved accumulated temperature is 2350 degrees Celsius, and the ideal dehydration effect and maturity will be obtained under the conditions of accumulated temperature above 2500 degrees Celsius, which is suitable for planting in Heilongjiang Province and the second accumulation temperate zone.

The seedling stage grows robustly, the plant height is about rice, the ear position is 95 cm, the leaves are raised, the plant type is convergent, the stalk is strong and not lodging, the live stalk is mature, it has good drought resistance and stress resistance, and is highly resistant to corn large spot, silk smut, corn tumor smut and bacterial wilt.

In the high-yield field, the average yield of Longgao L2 is more than 30,000 catties, far exceeding the varieties of the same maturity period, creating a record of high yield of corn in Heilongjiang Province, the commercial grain is grain, the rice quality is harder, the price is relatively high, the color of the commercial grain is golden, suitable as food raw materials, feed and brewing raw materials, the variety has aroused great enthusiasm from the industry and farmers around the world.

Specialty corn is a high-quality corn that is cultivated according to different needs and suitable for special purposes.

Corn varieties have the characteristics of specificity, high quality and high efficiency. At present, a number of special corn varieties with promotion and application value have been cultivated in China, which are mainly divided into 8 types: 1

Sweet corn is divided into ordinary sweet corn and super sweet corn, which is mainly used for fresh food and quick-frozen. Its characteristics are: high sweetness, the sweetness of ordinary sweet corn is about twice that of ordinary corn, and the sweetness of super sweet corn is more than 2 times that of ordinary watermelon; The peel is tender, the taste is waxy, the palatability is good, it can be eaten fresh, it can be quick-frozen and fresh, and it can also be made into canned food.

Straw is a high-quality silage. The varieties include the enhanced super sweet corn "Tiandan No. 8" cultivated by China Agricultural University, and the "Jinxian No. 1" cultivated by Tianjin Academy of Agricultural Sciences. 2.

Waxy corn is mainly used for fresh food. Its characteristics are: compared with ordinary corn, it is glutinous, soft and fragrant, sweet and palatable, and has a unique flavor.

Straw can be used as high-quality silage. The varieties include "Yannuo No. 6" cultivated by Shandong Yantai Academy of Agricultural Sciences, "Zhongnuo No. 1" cultivated by Chinese Academy of Agricultural Sciences, and "Lunuo Corn No. 1" cultivated by Inner Mongolia Chifeng Seed Company and Shandong Academy of Agricultural Sciences. 3.

High-oil corn is mainly used as a chemical raw material and processed for consumption. The oil content of high-oil corn kernels is as high as 8% 9%, which is about 1 times higher than that of ordinary corn. In particular, corn oil has a high ratio of oleic acid and linoleic acid, is rich in nutrients, and has good health care functions for the human body.

The variety has "Gaoyou 115" cultivated by China Agricultural University. 4.High-lysine corn is also known as high-protein corn and high-nutrient corn.

The content of lysine and tryptophan in its grains is more than 1 times higher than that of ordinary corn. Rich in nutrition and good quality, it can be used to make high-quality food, and can also be used as high-quality concentrate feed for livestock and poultry. The varieties include "Ludan 203" cultivated by Shandong Academy of Agricultural Sciences, "Zhongdan 9409" and "Zhongdan 3880" cultivated by Chinese Academy of Agricultural Sciences.

5.High-starch corn is mainly used in the pharmaceutical industry. The starch content in its kernels is higher than that of ordinary corn, and it is an important raw material for the manufacture of antibiotics.

The varieties include the high-starch variety "Sidan No. 19" cultivated by Jilin Siping Agricultural Science and Technology. 6.Corn for bamboo shoots Young ears of corn are called corn shoots, which are mainly used for vegetables.

Its characteristics are: a single plant has many spikes, generally a single plant has 4 6 spikes, its spikes are crisp and delicious, rich in nutrition, and are high-end dishes. The varieties include "Sweet Bamboo Shoots 101" cultivated by China Agricultural University, "Sweet Bamboo Shoots Miscellaneous No. 4" cultivated by Beijing Academy of Agriculture and Forestry Sciences, and "Lu Bamboo Shoots Yu No. 1" cultivated by Yantai Academy of Agricultural Sciences.

7.Green-fed corn is mainly used as silage. It has the characteristics of high yield, high quality and disease resistance, especially the yield of straw silage is higher than that of ordinary corn.

Varieties include "Liaoyangbai" cultivated by Liaoning Academy of Agricultural Sciences. 8.Burst corn is mainly used as a raw material for puffed food.

The corn flower is large, good in color, crunchy, fragrant, nutritious, easy to digest, and is a high-fiber, low-calorie carbohydrate food. The varieties include "Bai Nuo No. 2" and "Bai Zao Nuo" bred by China Agricultural University.

The accumulated temperature of 2100 in the early maturing area can be planted to ensure the harvest of 909, and the grain quality, resistance and yield are good.

So so. In general, it is no problem to produce 20,000 catties of dry food, but if you encounter lodging, you can only produce 15,000 or 6,000 catties.

Jiyan 94 corn varieties, 2008 provincial corn variety regional test (3500 plants 1 group), 12 points summarized all the increase in yield, the average yield per mu, compared with the control Jundan 18, the difference is extremely significant, ranking third among the 18 tested varieties; In 2009, the test was continued (3500 plants and 1 group), and the yield of all 10 pilots was increased, and the average yield per mu was increased compared with the control Jundan 18, and the difference was extremely significant, ranking second among the 19 tested varieties. Based on the two-year 22-point sub-mental stimulation test, the average yield per mu was kg, which was higher than that of the control Jundan 18, and the yield increase rate was 100%. In 2009, the provincial corn variety production test (3500 plant groups) showed that all the yields were increased at 9 points, and the average yield per mu was higher than that of the control Jundan 18, ranking 6th among the 9 tested varieties.
