Superior varieties of rubber trees are crucial elements in achieving stable production and supply of natural rubber. In China, rubber tree planting areas are situated at the northern edga of the world’s tropical zone and thus belong to non-traditional rubber tree planting areas with climatic conditions inferior to the traditional ones in Southeast Asia. The planted rubber trees are frequently damaged by low temperatures and diseases. Therefore, an urgent need in natural rubber production is to develop varieties with highyield potential and strong stress-tolerance. The scarcity of such varieties is mainly ascribed to the highly heterozygous genome, a long juvenile …
