Initial Studies Indicate Pinus Pesinosa Little Affected by Selfing
Most of the Pinus species studied exhibit a considerable amount of morphological variation, at least some of which can be attributed to genetic variation Red pine, Pinus resinosa Ait would appear to differ from many other members of the genus in that it exhibits very little morphological variation. If this uniformity is the result of genetic uniformity, then one would expect that red pine would be relatively self-fertile and selfed progenies would not exhibit many phenodeviants or suffer serious inbreeding depression in growth. To test this hypothesis, a series of experiments concerning the effects of inbreeding in red pine was initiated in 1958. This paper presents some of the preliminary findings of this work.
