From:
Charles Robert Darwin
To:
William Herbert, dean of Manchester
Date:
[c. 1 Apr 1839]
Source of text:
DAR 185: 62
Summary:

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?

To:
John Stevens Henslow
Date:
5 Apr 1839
Source of text:
DAR 185: 63
Summary:

Replies to CD’s questions on plant hybridisation and laws of inheritance. Rejects predominant transmission of characters by established forms. Males show predominance, but congeniality of parents’ constitution to climate and soil more important. No correlation between hybridisation and variability, cultivation, and geographical distribution. Rejects reversion.

Describes experiments in Hippeastrum in which pollen from another species proved more fertile than plant’s own pollen.

Did not intend to say that crossing is inimical to fertility.
