培育速生、优质、丰产、抗性强,具有观赏价值的云杉品种,是林业育种的一项重要任务。而达到这个目的最直接的途径,是在自然群体中选择特殊类型和优株,并用扦插法进行繁殖。扦插繁殖能够完整地复制母树基因型。近来,用幼龄植株扦插繁殖的方法选育云杉多系品种的设想已被广泛采纳。估计应用这些品种 Cultivating fast-growing, high-quality, high yield, strong resistance, ornamental value spruce varieties, is an important task of forestry breeding. The most direct way to achieve this goal is to select a special type of natural population and excellent strains, and cuttings propagation. Cutting propagation can reproduce the parent tree genotype completely. Recently, the idea of ​​using young plant cuttings to breed multi-line spruce varieties has been widely adopted. Estimated to use these varieties
