Questions on breeding of plants: variation in established versus new varieties; predominance of wild species and old varieties when crossed with newer forms; predominance of males versus females; correlations between ease of hybridisation and tendency to vary and undergo cultivation; reversion; correlations between hybridisation and geographic distribution.

In WH’s Amaryllidaceae [1837], does he intend to say crossing is inimical to fertility?

[Sent via J. S. Henslow; note to amanuensis Syms Covington.]

CD is led to believe there are no true permanently inbreeding, sexually reproducing beings. Thanks for replies to breeding questions.

Asks for clarification of Hippeastrum crosses: is selfing or crossing with individual of same species intended and was increased fertility due to constitution of foreign parent or due to the pollen coming from another plant? Has WH known any hybrid or mongrel to revert or to vary in a manner unlikely to be effect of soil?
