变叶海棠种群是变叶海棠与陇东海棠和花叶海棠3个种的杂交复合体,由于杂种的全部或部分能育子代中发生的基因重组和增加基因的突变率,丰富了物种的基因库,从而深入的揭示了变叶海棠具有高抗性的遗传机理。
Malus toringoides Hughes is a hybrid complex formed through one-way introgressive hybridization between M.
变叶海棠遗传多样性是变叶海棠与花叶海棠和陇东海棠产生单程渗入杂交形成的杂交复合体 ,该复合体经居群内变异、地方宗的分化、地理宗的分化 ,最后分化形成了多毛海棠。
planispium,and it had become a hybrid complex contained many populations with complicated genetic diversities;(2)Z.
结果表明:(1)九叶青花椒是花椒和竹叶花椒长期渗入杂交,经多年的世代积累形成的具有复杂遗传多样性的杂交复合体。
