双桂一号(即双桂210)是广东省农科院水稻研究所用“桂阳 C17”作母本与“桂朝二号”杂交,于1979年育成的水稻良种。该品种属感温性,早、晚造都可种植。早造种植表现为迟熟品种,全生育期131—140天;晚造种植表现为中熟,全生育期120天左右。矮秆,株高80—90厘米,基部节间短,分蘗力强,丛生,叶片短窄挺拔,叶色浓绿,有效穗数较多,有较好的丰产性,抗逆性较强,出米率高,一般为71.5%。不论山区、

Shuanggui No.1 (Shuanggui 210) is a rice cultivar bred in 1979 by the Institute of Rice Research, Guangdong Academy of Agricultural Sciences, using “Guiyang C17” as the female parent and “Guichao II”. The variety is a sense of temperature, early and late make can be planted. Early planting showed late maturing varieties, the whole growth period of 131-140 days; Late planting performance is medium maturity, the whole growth period of 120 days. Dwarf, height 80-90 cm, short basal internodes, strong tillering ability, tufted leaves short and narrow tall and straight, dark green leaves, more effective panicles, better yield, strong resistance, The rice rate is high, usually 71.5%. Regardless of mountain area,
