The Research Of Breeding And Promotion Of Virus-free Potato Seed In Shangluo

2015, Ministry of Agriculture potato staple food strategy, potato then become our fourth largest staple position in China’s grain production is becoming increasingly important.Potatoes also Shangluo City of food and cash crops, widely distributed in each county in Shangluo City, especially in the high mountains of the acreage is increasing, has become an important item in Shangluo City farmers to increase production of grain, potato farmers planted part uses from their own consumption of fresh potatoes into sales and autonomous processing. Shangluo City, the annual average up to 60 million mu of cultivated area, the total output of around 700,000 tons. But there exists in Shangluo City in potato production of hybrid varieties, seed degeneration serious and viral diseases and serious problems, directly affect the Shangluo potato yields, the quality and yield of potato caused enormous damage,affecting the development of potato industry in Shangluo.Popularization and application of virus-free potato seed is the fundamental way to solve the poor quality of potato yield is low. In shangluo virus-free potato seed breeding and promotion as the research object, first of all, according to the world of potato production in the food and agriculture organization(fao) and the national data network data, from the planting area, yield and yield analysis in three aspects: the world and the present status of potato production in China. In a comprehensive understanding of shangluo detoxified potato kind of potato breeding and promote the development of the present situation and after, using the literature research, on-the-spot investigation, experimental research and systematic analysis of the method of combining find shangluo detoxified potato kind of problems that exist in the potato breeding and spreading, and puts forward the countermeasures, the main results were as follows:1, through to the farmers use virus-free potato seed situation of research and shangluo detoxified potato kind of potato breeding promotion present situation analysis of the restriction of shangluo detoxified potato potato breeding promotion of main remaining problems are detoxified potato kind of potato production capacity is weak, the original seedbreeding base is small, its self-sufficiency rate of seedling to kind of potato is low, cannot satisfy the potato production with kinds of shangluo. Kind of potato sales system is imperfect,detoxification potato breeding system is not sound, breeding base construction at all levels is not standard, there is no standard of potato storehouse, bad kind of potato storage of potato chips, disease situation, kind of potato quality supervision vacancy, kind of potato market confusion, serious impact on the quality of the kind of potato; No suitable promotion mode makes the promotion of low efficiency, low penetration of detoxification of potato, according to the on-the-spot investigation, only 15.8% of farmers know that there are detoxified potato starch and used in the production of detoxified potato starch, most farmers do not understand detoxification potato production efficiency, not clear kind of potato classification, increase the difficulty that detoxified potato chips of promotion.2.Through the introduction of eight varieties and local cultivars were compared cultivation, potato yield basis, commodity potato rate and disease resistance and other indicators analyzed in this study were screened out on the 11 th of this Longshu varieties.Longshu on the 11 th in terms of appearance quality, yield, growth period and so the performance is more prominent, yield 1466.67 kg / 667m2, Atlantic than the control varieties yield 31.8%, significant at a significant level. More suitable for planting in Shangluo, it can expand production testing and demonstration, but because of its poor resistance must be used in the cultivation of virus-free seed production.3, in order to solve the problems of shangluo virus-free potato seed breeding and the existing in the promotion, in order to improve the yield of shangluo potatoes. Through analysis and research for the development of shangluo detoxification potato kind of potato put forward the following countermeasures: multi-channel form to increase more detoxified potato potato breeding of capital investment, investment promotion and capital introduction,direct financial credit funds into detoxified potato potato breeding projects, for detoxification potato potato breeding technology and marketing to provide strong support; On the basis of the existing various kinds of potato breeding base area, the original seed and seed production included in the scope of agricultural subsidies. Improve detoxification potato breeding system,implement the implementation of the breeding practice, strengthen quality management of kinds of potatoes and establish a detoxified potato potato certification bodies and quality inspection departments, in every link of the potato production quality supervision, and virus detection, to ensure the quality of kinds of potatoes. Establish scientific research units +farmers + enterprise promotion mode, foster a detoxification potato production of leading enterprises, scientific research units to sell its production of the original species to enterprises,mass production by the enterprise for seed, and farmers to sign orders production level in theform of potato and 2 kinds of potatoes, and unified management by the enterprise and implementation of the acquisition of peasant household production of secondary kind of potato, provide quality assured of shangluo local fine kind of potato, first of all meet the quantity of potato seed in shangluo, seedling in surrounding areas can also provide kinds of potatoes.
