硬粒小麦(Triticum durum)通常为开花受精,但偶尔也可见到闭花受精现象。用6对材料进行杂交并回交的遗传研究表明,开花受精是由显性单基因Cl控制的,闭花受精则由隐性纯合等位基因cl决定。这一开花习性不受环境条件的影响。闭花受精是浆片发育不良、花被坚硬的结果。 Durum (Triticum durum) is usually flowering insemination, but occasionally can also see the phenomenon of closed flowers fertilization. Genetic studies using six pairs of materials for hybridization and backcross showed that flowering and fertilization are controlled by the dominant single Cl, while flowering insemination is determined by the recessive homozygous allele cl. This flowering habit is not affected by environmental conditions. Closure of flowers is poor growth of pulp, perianth hard results.
