摘要

19941997 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 种间杂交组合亲和力极弱, F 1代杂种苗生长不良, 68 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 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” 、“ 紫云紫盘7

Abstract

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 Cloudand Purple Plate” .
