From July 15 to July 20, 1986, the Science and Technology Department of Yunnan Provincial Bureau of Land Reclamation held a review meeting of rubber strains at the Provincial Institute of Tropical Crops Science and Technology. At the meeting, Yunnan Hot Work Station, Dehong Test Station, Honghe Experimental Station and farms Rubber breeding breeding science and technology workers, experts and professors, a total of 27 leaders. South China Institute of Tropical Crops sent to the guidance. Through six days of on-site inspections and indoor appraisal, twenty-one large-scale, medium and small-scale promotion and trial-grade strains of Yunnan Reclamation were initially evaluated. After reviewing the meeting of the National Rubber Commodity Assessment Meeting, 14 rubber quality strains of Yunnan were finally selected. The brief introduction is as follows: 1. The large-scale promotion grade RRIM600 selected by the Institute of Rubber Research of Malaysia, whose hybrid parent is Tj1 × P B86 . Emerging: medium, planted in the sunny and fertile ground, in well-managed circumstances, 6.5-7 years after planting up to cut open standards. Yield: The production of the Department of the District than the District fifteenth cuttlebone production adhesive 5.06 kg, 107.29 kilograms per mu; production tree bitter year production adhesive 5.54 kg, 134.82 kg per mu; 6.8 kg dry glue, 148.8 kg per mu. A large area of Xishuangbanna reclamation area average yield 97.0 kg. Highest yield 226.3 kg.
