玉米自交系繁育既是一项技术要求严格的工作,又是玉米制种质量的关键所在。因此,在玉米自交系繁育过程中,必须采取严密防杂保纯措施,无论是在选地或具体操作时都必须严格按照玉米自交系繁育的操作规程进行,只有这样才能保证玉米自交系繁育的顺利实施,以达到玉米自交系繁育的真正目的。掌握好玉米自交系的防杂保纯技术,对于保持自交系的种性,提高种子质量具有重要意义。本文根据多年从事玉米自交系亲本繁育工作的经验,总结出提高玉米自交系防杂和保纯的繁育技术,以此来指导自交系生产。 Breeding of maize inbred lines is both a work of strict technical requirements and the key to seed quality of maize. Therefore, in the process of breeding of corn inbred lines, we must take strict precautionary measures against pollution, whether in the selection or specific operation must be strictly in accordance with the breeding procedures of corn inbred lines, the only way to ensure self-corn Department of the successful implementation of breeding in order to achieve the true purpose of breeding of corn inbred lines. Mastering the technology of hybrid inbred lines of maize is very important for keeping the inbred line variety and improving the seed quality. Based on the experience of parental breeding in maize inbred lines for many years, this article summarized the breeding techniques to improve inbreds and inbred lines of maize inbred lines in order to guide inbred line production.
