养麦是我国广为栽培的粮食作物,它抗旱耐寒适应性强,生长期短,在高寒山区为主要粮食作物之一,还可供药用。但荞麦的繁殖系数低于谷、糜、稻、麦、高粱和玉米。其异花授粉特性致使育种各级试验圃的籽实不能做种子。安全隔离区在5km以上。大大增加了养麦繁种难度和育种周期,为了使优良品系快速繁殖,我们进行了 Raising wheat is a widely cultivated food crop in China. It has strong drought-tolerant and cold-resistant adaptability and short growth period. It is also one of the main food crops in the alpine region and is also available for medicinal purposes. However, the coefficient of propagation of buckwheat is lower than that of rice, rice, rice, wheat, sorghum and corn. Its cross-pollination characteristic results in seedless breeding of seeds at all levels of the experimental nursery. Safety isolation zone in more than 5km. Greatly increased the difficulty of breeding wheat breeding and breeding cycle, in order to make good breed rapid propagation, we conducted
