唐菖蒲不同品种杂交F_1代性状初步观察

Preliminary observation on the characters in the hybrid progeny of Gladiolus

通过对大田以及温室栽培唐菖蒲品种进行杂交育种试验,共选用7个亲本配置1个自交系和6个杂交系,对其F1代的性状表现进行初步观察。结果发现,母本为深色系的品种性状表现较好,其中303×301组合和201×301组合的籽球性状表现较突出。在杂交组合内呈现主要性状的优良单株有(以A～G分别代表7组杂交组合)A3、B1、C1、D3、E2、F2和G1这7株是本次试验发现呈现出良好的表现型的杂交种。

7 parent plants were selected and 7 cross combinations were conducted among Gladiolus in the fields and green-house. Compared the character representation of F1 progenies,using the dark cultivars as mother plant could express better. From the proportion of diameter to bulb height, crossing combination 303~3Oland 201~301expressed better. There were some single plants of main characters in these crossing combinations,such as A3,B1 ,C1, D3,E2,F2 and GI, which expressed excellent phenotype in the experiment（A-G stands for seven groups of crossing combinations）.
