来自 Caloro X Blue Rose (2914A) 杂交的许多 F4 系分离出具有正常生长习性和平伏生长习性的植物。 “懒惰”的生长习性似乎是由于 F2 植物 (2914A2) 的隐性因子突变所致。对这种植物的后代以及“懒惰”X 蓝玫瑰杂交的 F2 和 F3 群体的遗传研究表明,“懒惰”生长习性是正常的简单隐性。在向地性响应中,“惰性”植物主要是向地性的,而正常植物是负向地性的。
A number of F4 lines from the cross Caloro X Blue Rose (2914A) segregated for plants of normal and prostrate growth habit. The "lazy" growth habit appears to be due to a recessive factor mutation in an F2 plant (2914A2). Genetic studies of the progeny from this plant and F2 and F3 populations from the cross "Lazy" X Blue Rose indicate that the "lazy" growth habit is a simple recessive to normal. In geotropic response the "lazy" plants are largely ageotropic, normal plants negatively geotropic.
