ABSTRACT

For clarification of an earlier work (Paiva et al., Brazil. J. Genetics 16: 1003-1011, 1993) we derive an expression for the variance of an estimate of the outcrossing rate (t) in plant species. This expression is adapted to the special case in which we test the hypothesis of panmixia (t=1). An example is given for illustration.

Keywords: variance; outcrossing rate.
