Title: Inbreeding in California Canning Clingstone Peach Cultivars

Abstract:
The inbreeding coefficients of commercially
important canning clingstone peach [Prunus
persica (L). Batsch] cultivars developed in California were found to be relatively low based on
pedigree analysis using the SAS INBREED
procedure.
However, coefficients of co-ancestry
between the likely parents of future generations
reveal an increasing probability of inbreeding.
This increased probability is primarily the consequence of past usage of a small number of
presumably unrelated parents in early crosses,
and extensive use of their progeny as parents in
subsequent crosses.
