油茶在长期的系统发育过程中由于自然和人工选择作用结果,在形态、生理、生态上产生许多变异,形成了多种类型,这些类型持有不同的经济性状,表现了不同的生产能力。调查发掘农家品种(优良小种群)进行类型(群体)选择,是现阶段油茶良种选育的重要途径之一。在经营管理粗放,处于半野生状态下进行群体选择,对产果量——遗传率较低的数量性状,不宜要求过高,因为栽培条件所限,生产潜力不能正常表现出
Camellia oleifera in the long-term phylogenetic process as a result of natural and artificial selection results in many morphological, physiological, ecological changes, the formation of a variety of types, these types of different economic traits, showing different production capacity. It is one of the important ways to breed elite seeds of Camellia oleifera at the present stage by investigating the choice of type (colony) of farm breeds (elite small population). In the extensive management, group selection in the semi-wild state, the quantity traits - the heritability of quantitative traits, should not be too demanding, because the cultivation conditions are limited, the production potential can not be normal
