高质量的种子是保证玉米高产稳产的重要生产资料,其产生是一个系统工程,是亲本种子繁殖、生产技术研究、大田制种、种子加工以及贯穿始终的质量监控等所有流程都完美执行的结果。了解国际上通行的种子生产过程,把握关键生产技术的每一个环节,先知先行者胜。亲本种子:决定杂交种的纯度在选育杂交种时,母本和父本分别来自两个独立的杂种优势群。母本群具有植株矮、果穗大、吐丝整齐、吐丝流畅、综合抗性好等优点;父
High-quality seed is an important means of production to ensure a high and stable yield of maize and is a systematic project that is the result of the perfect execution of all processes including parental seed multiplication, production technology research, field preparation, seed processing, and consistent quality control . Understand the world’s popular seed production process, grasp every aspect of key production technology, the forerunner win. Parents Seed: Determining the Purity of Hybrids In breeding hybrids, the maternal and paternal stems come from two independent heterotic groups, respectively. The female parent group has the advantages of short plants, large ear, neat spinning, smooth silking, good comprehensive resistance, etc. Parent
