摘　　要：连续3年调查测定银杏(G inkgo biloba L inn)良种桂G 86-1与海洋皇的原株生长性状、产量性状、果实性状及种仁营养成分。发现两个品种均具有高产、稳产、粒大、洁白、味美、质优的综合优良性状,桂G 86-1的果实性状和种仁营养品质均略优于海洋皇。桂G 86-1无性系后代在始果年限、投产株率、平均产量及果实性状等各方面均优于海洋皇无性系后代,较好的保持了原株的综合优良性状,但两个品种无性后代都与原株产生部分变异,其中以海洋皇无性系后代的变异性较大。The characteristics of growth, yield, fruit and the component of nutritions of Ginkgo biloba Gui G86-1 and Haiyanghuang were compared in 3 runing years. The results showed that the 2 cultivars had excellent traits in great and steady yield, big,white and flavorful seed. Gui G86-1 was better than Haiyanghuang in the characteristic of fruit and the quality of nutritions. However,the studies showed that the character of clonal offspring of Gui G86-1 is better than clonal offspring of Haiyanghuang in the time of starting fruit, setting ratio, average yield, fruit character et al. Gui G86-1 was keeping the excellent traits of their parent, however these two clonal offspring had produced part variation. These variation were different from their parent. However there was a greater variation on the clonal offspring of the Haiyanghuang than that of Gui G86-1.
