.Corn breeding program of the University, the research and development of corn farm to continuously for 45 years. The basic research 20%.Research and application 80% to meet the requirement, and solve the problems of the country. The development of hybrid corn open and hybrid high yield and diseases resistance to downy mildew to farmers plantingResearch and development of the cooperation from various agencies in both countries, including University of agriculture, Department of agriculture, Department of agricultural extension. Agriculture and seed companies.Including the carver. International Maize and Wheat Improvement Center (CIMMYT)
.
maize hybrid open good dominant
.Maize hybrid open play an important role in increasing the yield of the สองทศวรรษ past. Because hybrid open this enhanced high yield, resistance to downy mildew disease.The seed is cheaper. And farmers can keep the seeds for themselves 1-3 evil during them. Open pollinated varieties derived from breeding, especially qualify.Make the farmers the opportunity to use the seed better. Besides, hybrids sold a trade in that period. Most also yield higher hybrid open not obvious.Hybrid seed and during that period also more expensive open pollinated seeds 2-3 imaginable. Make the farmers used corn seed farm hybrid open more than hybrids
.Corn breeding program of the University. The research and development of corn hybrid open farm intensive continuously for 35 years. And have introduced hybrid open good to farmer include varieties.(B.Professor 2518), reduction 2 (the 2522), reduction 3 (the 2530) and reduction 5 (1999)2536) hybrid open and hybrid varieties, many of the public and private sectors, including improving the เขตกร culture. Is an important factor that effects of corn crop year 2518 / 19-2534 / 35 produced an average 372 kg / ha, yield of average 3.45 million tons and export value, average 6 059% higher crop year 2501 / 02-2517 / 18 which yield, average 313 kg / ha, yield of average 1.23 million tons. And export value, average 1 540 million, to 19%And 181% 293% respectively. Although corn hybrid variety plays an important role more and more in the 10 years later. But also the utilization rate of open pollinated seeds about 10% quantity of seed all
.A hybrid open reduction 1 whose role is most important. On the development of maize production in Especially in the era with downy mildew disease outbreaks are also more 20 countries, including CIMMYT has นำพันธุ์ Suwan 1.And use it as a good germplasm in breeding. Because the varieties with high stability of productivity, adjust wide resistance, mildew and leaf diseases.When mixed with inbred lines with yellow seed robber or semi robber of maize temperate or subtropical to hybrid high yield. And the disease resistance
.To build and improve reduction 1 began in BC.The number of 36 2512-2513 corn varieties. Most of which originated from the Caribbean islands 16 varieties. New Mexico and Central America, South America 6 varieties 5 varieties, Indian 5 breed and from other sources, including the United States, 4Then mix is a Thai composite number 1 (Thai Composite # 1), then use a S1 recurrent selection breeding method. Later born downy mildew disease outbreaks. Damage to corn and severely during the yearProf.2514-2516 corn breeding program started breeding resistance seriously. By using resistant varieties to downy mildew, Philippine DM R 1 and Philippines DM R 5 mixed with composite number, 1 Thai1 and mixed back to Thai composite number 1 qualifier and were 2 3 2 1 times respectively, and Thai composite 1 DM r backcross times 3 (Thai. Composite # 1 DMR BC3) or reduction 1 qualifying 0.Due to mix back times 2 3 selection and plant resistance to downy mildew disease outbreaks in the transform artificial
.After breeding, qualifying 2 the 2517 varieties Thai Composite # 1 DMR BC3 (S) C2 certified seed from the Ministry of agriculture and Cooperative in 2009.2517 and changed its name to "reduction" and the current 1 was selected to the qualifying 12 thousand varieties
.Engineering psychology 1 adapt to various environments have extensive testing of the production, and transplantation experiments in many countries in Asia. Africa, Central America, and South America. It appears that the reduction 1.Any good adaptation and feature is the resistance to downy mildew disease caused Suwan 1 เป็นพันธุ์ well top, as Dr.Takumi Izuno project specialist corn Asia of CIMMYT have praised the good.
