Inheritance Of Indumentum
David Leach, moderator of the "Rhododendron Round Table" at the Annual Meeting, had his own contribution on the subject of inheritance of indumentum on rhododendron leaves. It was summed up in a slide as follows:
( Catawbiense var. album x yakushimanum ) x yakushimanum = (non-indumented x indumented) x indumented
|Actual: 98 seedlings total|
Conclusion: indumentum is controlled by two genes, non-indumented being dominant.
