摘要
本试验在小麦生长锥伸长期和小花突起期,在小麦茎间下居间分生组织中注射外源DNA,受体小麦当代出现供体小麦的性状。显性目的性状出现的频率比隐性目的性状出现的频率高1.6倍。当代变异性状可在H_1代部分遗传,平均变异性状的遗传频率达82.6％
Exogenous DNA was injected into the intercalary meristem at stages from elongating of apical cones to differentiation of floret apex of winter wheat. In this generation (H_0), the plants of acceptors appeared the characters of donors. The appearing frequency of dominant aim characters was 1.6 times higher than that of recessive aim characters. The variant characters of H_0 generation could partly inherit to H_1 generation. The average inheritable frequency of variant characters reached 83%.
