Abstract
The use of superior rubber planting materials is one of the most important components of technology to support the cultivation and sustainability of the natural rubber industry. The effect of the genetic components of planting materials to the rubber productivity can reach 60%, and the rest is the influence of agro-climatic conditions. The aim of the rubber plant breeding program is to obtain the new superior rubber clones that have a high latex yielding potential and good agronomic characters. The fluctuations of natural rubber price and climate changes also influence the direction and objectives of the rubber plant breeding program. To deal with the conditions, it is important to provide the rubber agroforestry technology by through intercropping of rubber with various other crops. The article will provide the information about progress of rubber breeding program in Indonesia and it is role in supporting agroforestry system. Several of new superior rubber clones have been released by IRRI, and some of these clones such as IRR 112 and IRR 118 had been planting with rice, corn, and other crops by through rubber agroforestry system. The system was estimated be able to maintain latex yielding potential of clones as well as farmers’ income can be improved.
Highlights
Rubber (Hevea brasiliensis) is one of the commodities tha t ha s the most importa nt role for the Indonesian economy, both as a source of employment opportunity and income for farmers as well as a source of foreign exchange
Until 2018, the total area of rubber plantations in Indonesia was recorded at 3.67 million hectares, consisting of 88.13% smallholder plantations, 5.16% private plantations and 6.7% state plantations with total production reaching 3.63 million tons
It is known that the largest contribution to Indonesian natural rubber production was obtained from smallholder plantations
Summary
Rubber (Hevea brasiliensis) is one of the commodities tha t ha s the most importa nt role for the Indonesian economy, both as a source of employment opportunity and income for farmers as well as a source of foreign exchange. Until 2018, the total area of rubber plantations in Indonesia was recorded at 3.67 million hectares, consisting of 88.13% smallholder plantations, 5.16% private plantations and 6.7% state plantations with total production reaching 3.63 million tons. Based on this information, it is known that the largest contribution to Indonesian natural rubber production was obtained from smallholder plantations. Other factors contributed to exacerbating the condition of rubber productivity in Indonesia n recently was the outbreak of a new disease named by Pestalotipsis leaf fall disease that attacked rubber plantations in 2018 This condition affects the productivity of Indonesian rubber plantations which results in a significant decrease in farmers' income.
