Abstract: 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.
