1994～ 1997 年在南京进行了鸢尾属( I ris L.) 的种间与种内杂交育种试验。 结果表明:2 个种间杂交组合亲和力极弱, F 1代杂种苗生长不良, 6～ 8 周内死亡。 3 个种内杂交组合亲和力较强,F 1代杂种苗生长良好, 其中 2 个杂交组合 F 1代的花色由单基因控制, 未出现花色的分离;不同花色的德国鸢尾( Iris germanica L .) 品种 LP 和 PP 之间的杂交组合 F1代花色受多基因控制, F 1代杂种
花色出现明显分离, 从中选出了“ 紫金” 、“彩带” 、“ 金舞娃” 、“ 红浪” 、“ 水晶球” 、“ 紫云” 和“ 紫盘” 7 个
新栽培品种。
 

The interspecific and intraspecific cross-breeding of Iris spp .have been carried out from 1994 to 1997 .The results are as follows :Low cross-com patibility has been found from two combinations of interspecific hybridization, the F1 seedlings grew very weak and died within 6 to 8 weeks .High cross-compatibility has been found from three combinations of intraspecific hybridization and their F1 seedlings grew well; the flower color of the F1 seedlings of Iris tectorum × I .tectorum f .alba and I .tectorum f .alba × I .tectorum is thought being controlled by single gene whereas that of I .germanica LP × I .germanica PP being controlled by multigene and the flow er colour was separated .7 new cultiv ars have been obtained :“ Golden Purple”, “Colourful Ribbon”, “Golden Dancing Girl”, “Red Wave”, “Crystal Ball”, “Purple Cloud” and “Purple Plate” .
