我国著名小麦育种家李丕皋、封如敏利用小麦的4倍体、6倍体、异源8倍体及Rht10矮化基因,经过多次杂交和回交,前后历时29年,把分枝型圆锥小麦的分枝特性,成功地导入了普通小麦,育成了小麦超高产亚远缘杂交新品种“多枝多粒穗小麦——分33”。1994年我们会同有关部门引进该品种,通过试验认为:该品种耐寒、耐旱、抗病,品质好,产量高,而且适应性广,我国多数小麦产区均可种植。 分33,半冬性,株高70厘米左右,每个穗子有分枝10—14个,多达22个,整个麦穗看上去象高粱 China’s famous wheat breeder Li Pugao, Feng Rumin using wheat tetraploid, hexaploid, heterologous 8-ploidy and Rht10 dwarfing genes, after several hybridization and backcrossing, before and after 29 years, the branch cone Wheat branching characteristics, the successful introduction of ordinary wheat, bred into a super-high yielding wheat sub-distant hybrid new varieties of “more branches and more panicle wheat - points 33”. In 1994, we introduced this variety together with relevant departments. According to the experiment, we think that this variety is tolerant to cold, drought, disease resistance, good quality, high yield and wide adaptability. Most wheat growing areas in China can be planted. Divided 33, semi-winter, about 70 cm in height, each ear has 10-14 branches, up to 22, the whole wheat looks like sorghum
