Currently, there are 6 specializing areas of rubber tree cultivation, including areas like South East, Highland, Central and North… In order to create a rubber variety is able to resist harsh weather, all officials of Vietnam rubber research institute (VNRRI) have been researching around the clock to produce a new rubber variety.An arduous road of finding varietyStarting with 3,539 clone varieties, mainly from primordial gene bank in Amazon, VNRRI selects from 500 to 1,000 new varieties. It is an arduous task. However, time not only discourages researchers but also motivates them to fulfill duties.  VNRRI attempts to create rubber varieties can be resistant to severe climates, illness and give high yield.Researchers have had to travel many times to age-old rubber areas like Brazil, Malaysia, India… There they found outstanding genes involving resistant characteristics to cold, drought, diseases and then brought them to Vietnam. According to Dr. Tran Thanh, Variety Division deputy head of VNRRI, rubber tree has specific characteristics, thus hybridization, cultivation and caring are not easy. Every 5 years, due to changes of climates, yield and resistance of rubber trees can also change. “That’s why we do not allow ourselves to take any minute break. Neglectfulness can cause the national rubber industry to fall down”. This young scientist also shared experiences of rubber hybridization. Accordingly, to generate a rubber variety, we have to conduct many phases like parents’ varieties selection, F1 generation hybrid, 3 stages of selection, trial production… All these phases can take a lifetime to accomplish; however, the result is still not assured. Every year, the VNRRI hybrids successfully from 500 to 1,000 clone varieties. After selections, there are only from 5 to 10 new genes adding to the gene library of the institute. “This number may be too small, but we believe that these new varieties have high resistance and high yield”, he affirmed.  To most of South East farmers, the main source of income comes from “white gold” "Switchboard" of rubber tree growers!To rubber growers in Binh Duong province, VNRRI has been a familiar address whenever they need advices on techniques or tree diseases. Farmer Nguyen Van Quang at Tru Van Tho commune, Ben Cat district said, he used to buy rubber variety from outside providers, but tree were so weak. Therefore, he came to Lai Khe rubber experimental station, which is an affiliate of VNRRI. “Staff there was enthusiastic about counseling, and even showed me how to distinguish many types of rubber”. After that, he purchased a proper rubber variety to grow on his lands. But he could not find a good type, so he came back to VNRRI again. “Sellers said that is a variety named RRIV 124 advised to plant on South East area, but I realized that was not. Finally, I made a purchase at VNRRI to be assured.Division of Variety, Mining Physiology, Plant Protection of the VNRRI welcome daily hundreds of farmers, who come here because of problems concerning latex yield, fungus and caring methods… After being answered questions about pink parasitic fungus on rubber trees at Lai Khe rubber experimental station, farmer Tran Van Khuong asserted: “Thanks to being here, I realized I myself was so obsolete, and did not know about applying new technologies”. According to some farmer households at Minh Thanh commune, Dau Tieng district, where has high latex yield, most of rubber trees there were bought and received advices from VNRRI. “Firstly, I intended to grow RRIM 600 rubber variety, but officers of VNRRI recommended for RRIW 124. I disagreed. Thanks to persuasion of officers, I decided to grow RRIW 124”, said Mr. Danh Quang, one of large rubber plantation owners there. “If I choose RRIM 600, a recommended variety to plant on highlands, I have to get rid all of them now”.Reported by Dinh Thang – Translated by Ngoc Huynh
