非洲部分地区和南美洲广泛栽培的可可树,通常用种子或插条繁殖。实生苗,甚至经过选择的杂种实生苗变异性很大,因此,最好用高产无性系进行无性繁殖。用直立的直生枝插条虽能获得正常的可可树,但直生枝的数量有限;用数量较多的斜向扇形枝插条,则树型矮而开展,这种树在幼龄期难于获得产量。用组织培养法繁殖可可,比用种子繁殖或插条繁殖都优越,可快速生产大量理想的无性系。但用组织培养法繁殖可可树尚未报道过。如今已从可可的各种组织器官 Cacao, widely cultivated in parts of Africa and in South America, is usually bred with seeds or cuttings. Seedlings, even after the selection of hybrid seedlings variability is very large, therefore, the best clones with high-yielding clones. Although normal cacao trees can be obtained with upright straight branches, the number of straight branches is limited. With a large number of oblique fan branches, the tree is short and difficult to obtain Yield. Breeding cocoa with tissue culture is superior to breeding with seed or cuttings and enables the rapid production of large numbers of ideal clones. But breeding cacao tree tissue culture has not been reported. Nowadays all kinds of tissues and organs have been removed from cocoa
