摘要
本文综述了胚抢救在培育早熟桃、杏新品种,无核葡萄以及柑橘三倍体等果树新种质,克服果树远缘杂种不育、枣胚败育等方面所取得的成绩。同时对影响胚培养成功的因素如外植体、胚龄、培养基、培养及移栽条件等进行了探讨,最后初步提出了今后的研究方向。
The application and progress of embryo rescue in fruit breeding were reviewed in this paper. This technique play an important role in breeding earliness peach and apricot, seedless grape and triploid citrus, as well as overcoming the abortion in distant hybridization and in Chinese jujube. Meanwhile, several factors that affect embryo culture, e.g. the explant, maturation stage, medium, culture conditions and transplant technology, were briefly introduced. Finally, the directions on embryo rescue in fruit tree breeding were advanced.
