摘　　要：为培育更具观赏性和适应性的鸢尾新品种,本文以德国鸢尾品种花石竹、红兰、蓝色港湾、温莎玫瑰、西瓦为父本,以本地鸢尾品种溪荪鸢尾、花菖蒲、黄菖蒲、马蔺为母本进行杂交授粉试验。结果表明:10个杂交组合均得到了种子,但结实率不高,为16%~44%,其中黄菖蒲×蓝色港湾结实率最高,而花菖蒲×花石竹结实率最低;10个杂交组合单果种子数也存在一定差异,其中黄菖蒲×温莎玫瑰单果种子数最多,为49粒,而马蔺×红兰的单果种子数最少,为13粒;10个杂交组合方式杂交亲和力存在差异;综上所述,溪荪鸢尾×温莎玫瑰的出苗数和存苗数最多,效果最好。In order to cultivate new Iris varieties with more ornamental and adaptability,the cross pollination experiment was carried out with the German Iris varieties Iris Peach Picotee,Red Orchid,Blueharbor,Windsor rose and Iris Siva as male parents,and local Iris varieties Iris sanguinea,Iris ensata,Iris pseudacorus and Iris lactea as female parents.The results showed that,all the 10 cross combinations got seeds,but the seed setting rate was not high,ranging from 16%to 44%.Among them,the seed setting rate of Iris pseudacorus×Iris Blueharbor was the highest,while that of Iris ensata×Iris Peach Picotee was the lowest.The seed number per fruit of 10 hybrid combinations was also different,among which,the seed number per fruit of Iris ensata×Iris Windsor Rose was the highest,with 49 seeds,and the number of seeds per fruit of Iris lactea×Iris Red Orchid was the least,which was 13.There were differences in cross affinity among 10 cross combinations;In conclusion,the number of emergence and survival seedlings of Iris sanguinea×Iris Windsor Rose was the best.
