在甘兰的一代杂种优势利用上,当用品种作杂交亲本时,其优势表现、稳定程度及产品性状的一致性均不够理想,这与甘兰的异花传粉方式而导致亲本个体间遗传性的分化有直接关系。因此,选育性状优良、配合力高的自交系作为杂交亲本意义十分明显。甘兰是雌雄同花作物,花器又小,不可能用人工授粉生产杂种,利用一代杂种则须解决简易的制种技术。甘兰的自交不亲和性1926年已被发现,日本等曾先后育成优良自交不亲和系,使甘兰类
In the utilization of the first generation of hybrids, the superiority, the degree of stability and the consistency of the product traits are not ideal when the hybrids are used as hybrid parents, which is due to the cross-pollination of kalanim The differentiation is directly related. Therefore, it is very obvious that the inbred lines with fine selection and high combining ability as hybrid parents. Kalanchoe is a monoecious crop with small flowers and flowers. It is impossible to produce hybrids by artificial pollination. By using hybrids of this generation, simple seed production techniques must be solved. Self-incompatibility of sweetlan has been found in 1926, Japan has bred into good self-incompatibility, so that class
