为了培育速生、丰产的油茶优良品种,我所于1970年和1971年连续进行了油茶有性杂交育种试验,培育出了普小油茶杂种和普黄油茶杂种。目前杂种第一代(F_1)保存10株(其中普小油茶杂种2株,普黄油茶杂种8株),生长良好,平均树高分别为56厘米和79.4厘米。1976年开始开花结实,1977年收杂种第一代(F_1)种子67粒,今年培育出杂种第二代(F_2)苗木21株,幼苗高生长比广西岭洒软枝油茶快57.0—62.3%。
In order to cultivate high-yielding and high-yielding varieties of Camellia oleifera, we carried out sexual hybrid breeding experiments of Camellia oleifera in 1970 and 1971 successively, and cultivated the hybrids of Camellia oleifera and Camellia oleifera. At present, the first generation of hybrids (F_1) preserved 10 (of which 2 hybrid Camellia oleifera, 8 hybrid Camellia oleifera hybrids) grew well with average tree height of 56 cm and 79.4 cm, respectively. In 1976, it began to blossom and grow. In 1977, 67 first-generation (F_1) hybrid seeds were harvested. This year, 21 hybrid seedlings of F_2 were bred. Their seedling height was 57.0-62.3% faster than that of Guangxi Lingling sprig.
