Where to adjust the pattern of corn varieties?

The sale of Huang-Huai-Hai summer sowing corn area has come to an end, indicating that the overall situation of corn sales in 2015-2016 has been decided! According to relevant data, the corn acreage in four northeastern provinces fell by 30 million mu in 2016, while Henan Province in Huang-Huai-Hai may have dropped by 4 million mu. The adjustment plan of the planting area of major crops in the Agricultural Development Plan gradually began to have a significant impact on corn.

"difficulty, pressure, chaos, change": typical characteristics of Maize seed Industry Market in 2015-2016

"difficult": total corn seed supply exceeds demand; corn price and planting area "double drop" (especially in sickle bend); variety blowout, thousands of corn varieties participate in competition (statistics in 2014 have 936 varieties on the list); a large number of varieties are highly homogenized The total superposition of five factors, such as a large number of enterprises and a large number of dealers, from enterprises to dealers, and even to retailers, the competition is becoming more and more hot, showing that the market is becoming more and more difficult. Under this market pattern, some parts of the semi-arid areas of Northeast China, most of Shanxi Province, the small parts of Northwest and Southwest regions have returned to the "low-price areas" of seeds.

"pressure": affected by the market environment, there is a backlog of seeds to varying degrees from retailers, dealers and enterprises, and a large amount of returns has become the "new normal"!

"chaos": the situation of random production of small and medium-sized enterprises, random sales of dealers and random planting of farmers still exists.

"change": the replacement of corn varieties has become the only opportunity for enterprises and dealers to develop. This generation of maize varieties involves all the major corn growing areas in the country, but it is not noticed because of its obvious regional characteristics, but its magnificence can only be compared with the era of Zhengdan 958 in that year. Even the Xianyu 335 era did not cause variety changes in such a large area. Jingke 968 phenomenon, Tiannong 9 phenomenon, Xianyu 6531 phenomenon, transgenic corn phenomenon, "Dongdan 6531" phenomenon in Liaoning, "Dafeng 30" phenomenon in North China, "Integrity 16" phenomenon in Shanxi, "Red Axis" phenomenon in Huang-Huai-Hai, "Guidan 1810 phenomenon" in Guangxi, "Wugu 1790" phenomenon in Yunnan, "five grains" phenomenon in eastern Gansu, Xianyu 508 phenomenon in Ningxia, Xinyu 29 phenomenon in Jiuhe industry. * * KWS phenomenon in northern Xinjiang, "Syngenta" phenomenon in southern Xinjiang, and so on. Changing the pattern of the corn seed industry, some traditional large enterprises are still developing, some large enterprises are declining, some once large enterprises are returning, a number of emerging enterprises are rising rapidly, and a number of enterprises are facing life and death!

Which varieties may rise?

The main results are as follows: 1. The extremely precocious area of Northeast China is greatly affected by the reduction of maize area, but Ruifu No. 1 of Ruifu Agriculture in Heilongjiang Province has still achieved growth.

2. Corn varieties in the early-maturing to medium-mature areas of Northeast and North China are caught in a scuffle, and enterprises such as Pengcheng Agriculture in Heilongjiang, Xinxin seed Industry in Heilongjiang, Huanong Weiye in Beijing, and Sanbei Xianzhengda are still "starry". The strong entry of Dabeinong Group into Heilongjiang Longke seed industry will affect the pattern of seed industry in this area, which has attracted the attention of the industry!

3. In the semi-arid region of the middle and late maturity region of Northeast China, Jingke 968 completed the replacement of Zhengdan 958, including Shuangliao, Changling, western Songyuan to Da'an, most of Tongliao and Chifeng Aohan in Inner Mongolia. Since then, the history of Zhengdan 958 as a large variety in Northeast China has officially ended. Among the six development enterprises of Jingke 968, Beijing Denong, Beijing Tunyu, China species Group, Shandong Denghai, Henan Hyundai and Beijing Shunxin Agriculture, Beijing Denong and China seed Group are members of the four Zhengdan 958 development enterprises!

4. In the semi-humid area of the northeast mid-maturity area, the first generation of varieties was caused by lodging and leaf spot disease in 2012, and Xianyu 335 declined in an all-round way. the main varieties participating in the replacement were Liangyu 99, Liangyu 66, Tiannong 9, Nong Hua 101 and so on. In 2015, another variety replacement was caused by low temperature sowing in spring and local severe drought.

5. In the late ripening area of Liaoning, the first variety replacement was caused by "corn big empty stalk" in 2010, and the second variety replacement was caused by the outbreak of armyworm in 2012. in this cycle, Dongdan 6531, popularized by East Asian seed industry, rose strongly. 2016 will be the general test of Dongdan 6531, which already has several million mu. The strong return of East Asia, which occupied 50% of the market in Liaoning before 2010, and the breeding achievements of breeder Wang Zhongyu will be answered in 2016!

6. The difference between Dafeng 30 of Shanxi Dafeng seed Industry in North China and honesty 16 of Shanxi Integrity seed Industry is that one is a big star and the other is a small star! Shanxi Xianyu 696 has become the absolute first main variety. In fact, Xianyu 696 has become an important variety since Heilongjiang, Inner Mongolia Xingan, Chifeng and Xianyu 696. A variety examined ten years ago at the same time as Xianyu 335 is now so successful. This phenomenon is enough to make people in the industry ponder!

7. The change of variety structure in Huang-Huai-Hai summer corn planting area, the second largest maize planting area in China, is the biggest since Zhengdan 958 replaced Nongda 108 in 2003. Because the maize varieties planted in Huang-Huai-Hai had a high degree of consanguinity, it led to a global resurgence of bacterial wilt in 2014, and a specific disease-southern rust swept through Huang-Huai-Hai in 2015, which finally brought about major changes in corn varieties in Huang-Huai Sea.

The varieties participating in this change are Denghai 605 of Denghai seed Industry, Xianyu 335 of Denghai Vanguard, Yufeng 303 of Lianchuang seed Industry, Lianchuang 808, Huanong 138 of Beijing Huanong Weiye, Huayu 168 of Henan Huafeng seed Industry, Nonghua 816 of Golden Agricultural seed Industry, Yuyu 30 of Henan Qiule seed Industry, Qiule 218, etc., in addition, there are also Agricultural University 372 and provincial examination varieties Zhongdi 88, Qiaoyu 8, Songyu 619 and so on. The market share of these varieties in Handan of Hebei, Dezhou of Shandong, Nanyang of Henan, and Fuyang of Anhui has reached an astonishing degree, and caused great changes in most of the varieties in the Huang-Huai Sea area except the following areas north of Xingtai, Hebei (except Hengshui), Shandong Jiaodong, Jiangsu, Jiangsu and Henan. Because the ear axis of the varieties listed above are all red, this variety change is called "Red Axis Storm" by dealers. But in fact, the old variety Liyu 16 promoted by Orejin and Liyu 88 of Hebei Zhaoyu seed industry also achieved reverse growth because of their excellent resistance to southern rust, and the two varieties listed above are white axis. These varieties of Huang Huaihai will be subject to general inspection in 2016!

8. In southwest Guangxi, Guidan 0810, popularized by Guangxi Zhaohe seed industry, has broken through the encirclement of Dika series, Zhengda series and Sunda 901 and Sunda 903, and has grown into the largest variety, while in Yunnan, Wugu 1790 of Gansu Wugu seed industry has become the top two varieties, and its single-grain sowing, high density, good quality and high value should have a great impact on the traditional southwest region. The emerging enterprises in the southwest region also include Hengmao in Guangxi, Chongqing luxury seed industry, Hubei Kangnong seed industry and so on.

"prolific" breeders continue to set new records

In the field of corn breeding, many breeders, such as Mr. Li Denghai, Mr. Song Xieliang, Mr. Zhao Jiuran, Mr. Wang Yibo, Mr. Wei Wei, Mr. Li Guobin, Mr. du Xianzhang, Mr. Zhao Jinlin, Mr. Guo Guoliang and so on, are famous for breeding many varieties.

From the perspective of national examination, Mr. Wang Yibo of Lianchuang seed industry has bred and reviewed Lianchuang 808 and Yufeng 303, and another variety Zhongkeyu 505 is in the approval process. Mr. Xiao Bixiang of Huanong Weiye in Beijing has bred and examined Huanong 138 in Huanghuaihai District and Huanong 887 and Huanong 886 in East and North China. Mr. Wang Zhongyu bred and examined Nong Hua 816 in Huang Huai Hai District and Jinhua 150 and Nong Hua 206 in East China. Another variety Dongdan 6531 was listed as the leading variety by the Ministry of Agriculture in Liaoning Province. The above records are likely to be rewritten in 2016.

Four varieties bred by Mr. Li Shixiao, who graduated from Gansu five Grain seed Industry and China Agricultural University, will end the national test and enter the approval process, involving the main producing areas such as East and North China and Huang Huaihai. If you include the two varieties he has already examined in the country, more than a dozen provincial varieties, another record breeder is about to be born!
