一般说来,菊花新品种的育成,除现代的辐射育种,组织培养法等新手段外,不外两种:其一是利用菊花天然的芽条变异做为母本,以无性繁殖法加以固定,推出新种;另一种方法就是本文将谈到的杂交育种法。天然芽条变异因有很大的偶然性和不确定性,故在新种培育上较受限制,而更多的则是借助于有性繁殖的方法,利用菊花遗传基础中广泛的变异性,通过杂交,有目的地选育新品种。
In general, new varieties of chrysanthemum bred, in addition to modern radiation breeding, tissue culture and other new means, no two: one is the use of chrysanthemum natural bud mutation as a female, cloned by asexual method , Introduced a new species; the other method is this article will talk about the hybrid breeding method. Natural buds mutation due to a great chance and uncertainty, it is more restricted in the cultivation of new species, but more by means of sexual reproduction method, using the genetic basis of a wide range of variability, through Hybrid, purposeful breeding new varieties.
