Propagation of rubber
.Breeding of rubber past will focus on Breeding on the part of the (stock) to get thousands of varieties that look exactly as required. Ng et al (1981) and Abbas Ginting (1981) and report.Goncalves (2002) reported that the production of rubber is different about 18 - 20 percent. Due to the use of the different varieties, but at present the rubber, traditional varieties used to นตอ. Was felled and planted with rubber seed RRIM600 replacement.One major problem is the root system of rubber varieties have strength less than traditional varieties and durable at the root diseases. If an outbreak of disease roots. The source of all may be destroyed. Since there are genetically similar.Because the rubber trees are a self-incompatible (cross pollination crop) version you have genetic variants (heterzygote). That looks not like the mother. Therefore, it is necessary to use the various parts. Of the stem in the propagation by means of persistent instead.Clone () is clone genotype as the mother in all respects. So it can keep good stability to rubber next
.Generally, the material of rubber in the rubber planting, including the year, rubber trees, grocery bags, and in the field, ต้นติดตา (Rubber Research Institute2553), but the plant material used most is the eyeball. Method which is derived from the traditional rubber seed varieties planted. Using tree branches and persistence looks good breeding The tree that meets the varieties. Using rubber traditional varieties etc. the stump.The genetic base width, root system, strong and durable as well, so finding the root disease of breeding of rubber. A strong root system growth. Has good compatibility with eye varieties and resistant to disease, root is important!
