摘　　要：以优质、有香气、特晚熟的龙眼果实性状为主要育种目标,选育出优异的龙眼新品种‘晚香’。该品种单果重13.5g,大者可达15.0g以上;可食率67.9%～71.3%;含糖量高,可溶性固形物含量21.9%～22.6%,最高达24.6%;肉质爽脆、致密,化渣,汁液中,不流汁,极易离核;口感好,香气浓郁,极宜鲜食。在福州,果实10月中旬至11月下旬成熟;果实退糖非常缓慢,挂树期长,挂树期间其果实鲜食品质没有明显下降,仍具有良好的商品价值。晚香龙眼果实综合经济性状明显优于国内外晚熟龙眼主栽良种立冬本和苗翘,是一个很有希望的鲜食龙眼新品种,具有广阔的推广应用前景。Based on the characteristics for quality, aroma and very late - ripening as breeding goal, ＇Wanxiang＇ longan was sellected as a new cultivar for future culture. The new longan cultivar had some good characteristics, followed by fruit weight for 13.5 g （max to 15.0 g）, edible percent for 67. 9% -71.3%, total soluble solid content for 21.9% - 22. 6% （max 24. 6% ） . At the same time, aril for crisp, melting, densy, dissociable from seed, middle juice, good taste and strong aroma. The mature period was from mid - October to late November in Fuzhou. And the sugar reduced slowly. The time for keeping repened fruits on trees was up to about 45 days, which had good commercial value. ＇Wanxiang＇longan, super to main late -ripening longan cultivars as ＇Lidongben＇ and ＇Biekiew＇ in the world on comprehensive economic traits, was a very promising longan cultivar and had a good prospect in application.
