现代分子辅助育种可以通过分子标记技术对玉米抗病、抗虫、抗涝、抗旱等抗逆性基因进行定位,为这些抗逆基因的克隆、转化及利用打下基础,有利于加快育种进程,缩短玉米育种年限。为了实现这一目的,需要对玉米种子进行高效、优质的筛选。目前国内采用手工取样,取样质量不仅参差不齐、而且难以保证种子活性,取样效率也低。美国孟山都公司、先锋公司研制的高速玉米取样设备可实现玉米高速取样,但都是采用特殊或者复杂的机构实现的,对于玉
Molecular marker-assisted breeding of modern molecular-assisted breeding of maize resistance genes, insect resistance, waterlogging, drought resistance and other resistance genes to lay the foundation for the cloning, transformation and utilization of these genes will help speed up the breeding process and shorten Maize breeding years. In order to achieve this goal, the need for efficient, high-quality screening of corn seeds. Currently using manual sampling, sampling quality is not only uneven, but also difficult to ensure the seed activity, sampling efficiency is also low. The United States Monsanto, Pioneer developed high-speed corn sampling equipment to achieve high-speed corn sampling, but are used to achieve special or complex institutions, for the jade
