How to Improve the Purity of Maize Hybrid Seeds

How to Improve the Purity of Maize Hybrid Seeds

I. Strict Inbred Lines The purity of the management inbred lines is the key to the ability to produce high-purity seeds. Therefore, strict supervision of inbred line reproduction is required. The provincial seed management departments have designated strong technical forces, and those with strict management measures are responsible for breeding tasks, or are used by provinces, localities, and counties. Inbred lines with less market or newly promoted varieties should be produced by the breeding units. We must guard against illicit transactions and ensure the typicality of the inbred lines. Second, from the fundamental grasp, strict breeding procedures Inbreeding propagation must adhere to the original original species → original species → original generation → inbred line program, inbred lines only continuous propagation use 2-3 years in the inbred line In the breeding process, we must strictly remove impurities, and change the original species every 2-3 years to maintain the original species of inbred lines. In addition, the inbred breeding units must keep a certain number of original species, expand it once every few years, extend the service life of the inbred lines, ensure the need for replacement of the inbred lines by various seed production units, and increase the number of hybrids. purity. 3. Establishing a stable, specialized and commercialized seed production base This is a necessary condition for the production of high-purity corn hybrids. It is necessary to select village settlements with superior natural conditions, effective leadership, high enthusiasm for mass production, and high scientific and technological quality. As a seed production base, to carry out large-scale and specialized seed production, it is necessary to strengthen technical guidance, increase seed production, and provide farmers with benefits. We must link quality with price, strict standards, quality and price, and correctly reflect high quality and high prices. We firmly reject the seeds of unqualified quality, allow farmers to consciously improve their sense of quality and efficiency, ensure the healthy and orderly development of the seed production base, and lay a good foundation for the long-term production of high quality seeds. Fourth, pay close attention to the full management of seed quality, and strictly control the "Six levels" Corn seed production through selection, soaking, germination, impurity removal, castration, harvesting, drying, selection, quality inspection, storage and storage, etc. This is a systematic project. Each link is interlocking, interdependent and interconnected. Whether or not the quality of seeds can be ensured is not a problem. We should focus on the following “six levels”. This "six off" is the parental off, isolation off, get rid of miscellaneous customs, emasculation off, harvest off and quality inspection. If this "six off" can be strictly operated according to the "Maize Hybrid Seed Production Technology Operating Regulations", then Must be able to produce high-quality, high-purity maize hybrid seeds to ensure the superior corn hybrid seed production in grain production. V. Raising ideological awareness and enhancing quality awareness The quality of inbred lines is directly related to the purity of hybrid seeds. With high-purity hybrids, coupled with other appropriate energy input and advanced cultivation techniques, they can win high quality and high yields. Otherwise, it will be done before work, labor and people will suffer financial loss, and lose the effect of increasing production of fine varieties. Therefore, various seed production units must ideologically attach importance to seed production and strict standards of action. They must also think about the peasants' thinking and the urgency of the peasants. They should raise awareness of the “three rural issues” and quality of service, and must put the seed quality in perspective. In the first place of all kinds of work, we must establish long-term quality awareness and make due contributions to increase agricultural output and increase farmers' income.
