General Description: This variety is an elite new clone derived from a cross between Reyan 8813 as the female parent and Reyan 217 as the male parent. It is characterized by high yield, early maturation, and stable production, and is currently one of the highest-yielding varieties in China.

Characteristics: At the seedling stage, the stem is erect with horseshoe-shaped leaf scars. The buds are positioned close to the leaf scar, and the scale scar and stipule scar are confluent in a linear form. The leaf cluster is distinct and conical. The petiole spreads horizontally, with shallow grooves on the lateral petiolules; the pulvinus is approximately two-thirds of the length. The leaflets are thick, elliptical, and the cross-section is a shallow "V" shape, with smooth margins. The three leaflets are closely arranged, deep green in color, and glossy on the surface. During the 1st to 11th tapping years, the average annual dry rubber yield is 5.77 kg/tree, equivalent to 2,504 kg/ha (167 kg/mu), which is highly significantly greater than that of RRIM600.

Application: After the commencement of tapping, the tree grows relatively slowly, while its wind resistance is comparable to that of the control variety RRIM600. It is suitable for promotion and planting in moderate wind zones in central and western Hainan Province, as well as in the Lincang and Xishuangbanna Class I rubber planting areas in Yunnan Province. Productive trial planting may be conducted in other suitable regions.
