橡胶育种的目标橡胶育种的目标在各种程度上受到物理、生物、工艺、经济状况和社会环境的制约。因此,育种的目标也随着时间的推移而改变。目前,广泛的目标是培育出具有下列这些特点的无性系:1.高产——在胶树大部分经济寿命中能保持高产;2.对低强度割胶和刺激反应良好;3.速生早熟——开割前后均生势旺盛;4.树型和分枝习性良好——抗风;5.抗 The goal of rubber breeding The goal of rubber breeding is to various degrees constrained by physical, biological, technological, economic and social conditions. Therefore, the goal of breeding also changes over time. Currently, a broad range of goals are to develop clones that have the following characteristics: 1. High yield - Maintain high yield during most economic life of the gum tree; 2. Good response to low-intensity tapping and stimulation; 3. Premature birth - Strong growth potential before and after cutting; 4 good tree and branch habits - wind; 5 anti-
