摘要
１９９４～１９９７年在南京进行了鸢尾属（ＩｒｉｓＬ．）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，Ｆ１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，Ｆ１代杂种苗生长良好，其中２个杂交组合Ｆ１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（ＩｒｉｓｇｅｒｍａｎｉｃａＬ．）品种ＬＰ和ＰＰ之间的杂交组合Ｆ１代花色受多基因控制，Ｆ１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 compatibility has been found from two combinations of interspecific hybridization, the F 1 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 F 1 seedlings grew well; the flower color of the F 1 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 flower colour was separated. 7 new cultivars have been obtained: “Golden Purple”, “Colourful Ribbon”, “Golden Dancing Girl”, “Red Wave”, “Crystal Ball”, “Purple Cloud” and “ Purple Plate”.
