摘要
采用大树嫁接方法,选择40个优良无性系进行全国区域性测定;经连续四年测产及果实品质测定,选育出赣_1(区4)、亚林_4(区24)等19个高产新品种。选出的新品种平均每公顷产油450 kg以上,比参试无性系均值高15％以上;比现有茶林产油高3～5倍以上。这是我国第一批经三轮选择、测定而选育出的高产新品种。同时,研究和解决了优良无性系造林搭配及可配性大小等问题。现已营造的大面积采穗圃及示范林,在造林和低产林改造中获得了显著的经济、社会效益。
40 elite clones were tested by grafting on mature trees in regional experiment. 19 new prolific varieties of Camellia oleifera, such as Yalin No. 4 (Ju No. 24) were selected based on data of oil production and fruit quality in four consecutive years. The mean seed oil (450kg per ha) obtained from new varieties was increased by 15% than the mean value from all tested clones, and was 3-5 times over the oil production in normal tea-oil tree stand available. Those varieties were the first batch of new prolific ones bred by three-round selection and regional test, also possessed great scientific merit and importance. This research solves the problems of matching elite clones in a stand. At present, large-area nurseries of scion-plucking and demonstration stands established with above elite clones played positive role in the establishment of new stand and improvement of poor old stands, and achieved significant economic and social benefits.
