C. Damgaard et V. Loeschcke, GENETIC-VARIATION FOR SELFING RATE AND THE DEPENDENCE OF SELFING RATEON MATING HISTORY IN BRASSICA-NAPUS (RAPE SEED), Heredity, 72, 1994, pp. 570-573
Significant genotypic variation for selfing rate was found in the summ
er-annual rape seed variety Topas. The 'broad-sense' heritability of s
elfing rate was estimated as 0.80 and the 'narrow-sense' heritability
as 0.41. Outcrossed plants had a significantly higher selfing rate tha
n selfed plants. The relationship between plant size and selfing rate
was ambiguous. The evolution of selfing rates is discussed.
