矮生型、短枝型苹果新品种的快速选育方法,对加快更新老品种,促进生产有重要意义。矮生型或半矮生型的苹果,适于密植、丰产、稳产,易修剪,便于机械化管理等优点。本方法采用凝胶电泳技术,可将矮生型、普通型的1～2年生实生苗区分开,准确率为84.37%。提前5～6年选择淘汰,从而提高育种效率。本方法适用于苹果属的不同种,其指标受遗传控制,因此稳定可靠,不受外界条件影响。所用仪器、药品简单价廉,操作简便,适于基层研究单位使用。
Dwarf type, spur-type rapid selection of new varieties of apple breeding methods, to accelerate the update of old varieties, to promote production of great significance. Dwarf or semi-short-type apple, suitable for close planting, high yield, stable yield, easy to trim, easy to mechanize management and so on. The method uses gel electrophoresis technology, which can distinguish the short-lived and ordinary-type 1 to 2-year-old seedlings with the accuracy rate of 84.37%. 5-6 years in advance choose to eliminate, thereby enhancing breeding efficiency. This method is suitable for different species of apple genus, its indicators by genetic control, so stable and reliable, free from external conditions. The instruments, medicines simple and inexpensive, easy to operate, suitable for grass-roots research units.
