为了提高橡胶产量,降低生产成本,尽早获得较好的经济效益,科学工作者把橡胶育种工作列为最主要的研究课题之一。按常规的方法,培育一个品系需要28～30年,又由于只有1‰的选出率,因而需要花很长的时间才能从大量的参试材料中选出一个新品系。橡胶育种工作者早就提出过必须缩短育种年限,提高选出率这个问题,同时也提出解决这个问题的唯一方法,就是对苗木进行早期选择。马来西亚橡胶研究院对产量预测这项工作开始较早,但对抗风和抗寒预测几乎没有开展工作。在产量预测方面他们曾对100个无性系18个月生的芽接苗用锋利的小刀进行刺检,
In order to improve rubber production, reduce production costs and get better economic benefits as early as possible, scientists have made rubber breeding one of the most important research topics. Conventionally, it takes 28 to 30 years to breed a strain, and because it has only 1% selection rate, it takes a long time to select a new strain from a large amount of tested material. Rubber breeders have long raised the issue of shortening the breeding period and increasing the selection rate. The only way to solve this problem is to make an early choice of nursery stock. The Malaysian Rubber Research Institute started an early forecast of production, but hardly any work on wind and cold forecast. In the field of production forecast, they once pricked the budding seedlings of 100 clones of 18 months with sharp knives,
