【摘要】 为了研究3种山羊草细胞质对普通小麦穗部性状的遗传效应,以普通小麦品系303,706及利用其回交转育的粘果山羊草（Ae.kotschyi）、瓦维洛夫山羊草（Ae.vavilovii）和牡山羊草（Ae.juvenalis）细胞质雄性不育系为母本、13个普通小麦品系为父本,进行不完全双列杂交,研究了瓦维洛夫山羊草、粘果山羊草、牡山羊草三种细胞质对普通小麦F₁代穗部性状的细胞质效应。试验结果表明,与普通小麦细胞质相比,三种山羊草细胞质对普通小麦有效小穗数和无效小穗数不产生正向和负向的细胞质效应。更多还原

【Abstract】 In order to analyse the cytoplasmic effects of 3 Aegilops (Ae. Kotschyi, Ae. Vavilovii and Ae. juvenalis)on T. aestivum’s spike traits, 104 hybrid combinations were made from incomplete diallel crosses, in which common wheat 303, 706 and their transformed male sterile lines with 3 types of Aegilops cytoplasms (Ae. Kotschyi, Ae. Vavilovii and Ae. juvenalis) were used as the female parents, and 13 common wheat lines were used as male parents, respectively. The results showed that there were no significant positive or negative cytoplasmic effects on the effective spikelet number and ineffective spikelet number of T. aestivum’ s F1 comparing with the cytoplasm of T. aestivum.更多还原
