以翠雀花（Delphinium elatum）和翠雀花（D. nudicaule或D. cardinale进行了生产红花翠雀品种。离体萌发技术是产生种间杂种的有效方法。从800粒种子中获得379株种间杂种植株。这些杂交植物的形式介于亲本之间，并且由于飞燕草素衍生物的存在，它们的花色是略带紫色的。这些杂种植物大多数是可育的。F1代为自交和姊妹交。在第二代中，从224株植株中筛选出6株粉红色或红色的植株。
Interspecific crosses between Delphinium elatum and D. nudicaule or D. cardinale were carried out to produce red-flowering Delphinium varieties. An in vitro germination technique was effective to produce interspecific hybrids. From 800 seeds, 379 interspecific hybrid plants were produced. The form of these hybrid plants was intermediate between that of the parents and their flower color was purplish due to the presence of delphinidin derivatives. Most of these hybrid plants were fertile. The F1 generation was self- and sib-crossed. In the second generation, six plants with pink or red flowers were selected from 224 plants.
