Description
Technical field
The invention belongs to crops breeding technique field, a kind of specifically method that adopts the high-efficient breeding of wheat technology to cultivate good quality and high output, how anti-new variety of wheat.
Background technology:
Majority state is all breeding of new variety and the Seed Industrialization emphasis as the wheat industry development in the world, developed country is according to the variation of the market demand, all the time the seed selection of high-quality specific breed is put in the first place, guaranteeing its advantage in the international market, and make every effort to making new breakthroughs aspect breeding material, method and the theoretical research.The breeding scale enlarges day by day, and greenhouse experiment is good, field machineryization, and the strange land adds that generation, shuttle breeding, multiple spot are identified and early is widely used for attribute test etc. and standardizes.Aspect breeding for quality, except that noting protein, strengthened the starch gelatinization The Characteristic Study in recent years.Attribute test further develops to quick and micro-direction, and near-infrared grain analysis instrument, quick viscosity apparatus, single grain hardness tester etc. have been widely used in breeding and have selected.Australia, the U.S. and Canada is in order to seize the wheat market of China, is devoted to the research of noodles and steamed bread quality since the late nineteen eighties, emphasizes the seed selection of bread, noodles and bread, steamed bun dual-purpose type kind.Aspect disease resistance, pay attention to the development and utilization of slow characteristic of disease/durable resistance and made great progress.Generally note simultaneously improving yield potentiality (all the more so), improving the liquid manure utilization ratio,, improve the market competitiveness of wheat to reduce production costs in developing country.
Liberation is over 50 years, and China's wheat breeding has been obtained remarkable progress, and is particularly outstanding aspect raising output.In the face of China joined WTO, big and medium-sized cities are built, living standards of the people improve and growing population pressure, China's wheat breeding should improve quality as early as possible, improves constantly yield per unit area again, also will improve the level of resources utilizations such as liquid manure.The quality-improving of China starts from the eighties mid-term, " eight or five " and the enforcement period of the ninth five-year plan, introduced some external high-quality resources and it has been transformed, excavate and created a collection of high-quality breeding material, cultivate the new varieties that some product are of fine quality, output is high, and large tracts of land is promoted.Special-purpose bread wheat breeds such as excellent 9507 for example, Jinan 17, Henan wheat 47, Gaocheng 8901 under the support of agriculture spanning plan, are carried out pilot scale and industrialization development, have obtained better progress.Also do more work aspect storage protein, starch gelatinization characteristic, the research of noodles processing quality, and proposing the tentative programme of national wheat quality zoning.
But also there are many problems in China's quality of wheat improvement, it is low to show as the winter wheat breeding efficiency on the one hand, breeding cycle length is the bottleneck of winter wheat high-efficient breeding, and the breeding technique system is to shorten breeding cycle efficiently, improves the effective way of efficiency of selection and breed breeding quality.Available on the other hand high-quality resource shortage, external quality germplasm is difficult to direct utilization because of economical character or bad adaptability; Method of testing also needs further perfect, presses for the trace test technology fast and accurately of setting up; The research of noodles and steamed bun also need be deepened and be strengthened.The quality stability of existing fine quality, yield potentiality, resistance, rich water utilization ratio etc. are still waiting to continue to improve, and general performance and common variety still have certain gap, so promotion rate is still slower, and coverage rate is little.Though the seed selection of super high-yielding kind obtains certain progress, also there is not large-area applications in production.The disease resistance of main breed (especially powdery mildew) is also not really up to the mark, causes a large amount of applying pesticides, and the rich water availability also remains to be improved.Domestic also inreal implement effective breeding methods such as shuttle breeding, multiple spot evaluation, the bad adaptability of improved variety.Generally speaking, the winter wheat breeding cycle is long, and the accuracy of selection is not high.On organizational form, breeding units is fought separately, and different subjects lack effective cooperation, cause breeding efficiency low, and overall competitiveness is not strong.
