Abstract

Lizard's Tail and Little Turkish varieties vary considerably as to time for floral abscission, anatomy of the abscission zone, and the controlling chemical agents. When the two varieties are crossed, a homogeneous F₁ generation is intermediate in anatomical characteristics and time required for abscission of unfertilized flowers. The F₂ individuals are widely heterogeneous. External anatomy and time of abscission vary considerably and in some instances are unlike either parental type or the F₁ offspring. Simple laws of genetics do not apply to the genetic effects upon floral abscission in these varieties. Multiple genes appear to be involved, as well as several instances of lack of dominance of individual genes.
