Fertility variation and its effect on diversity over generations in a teak plantation (Tectona grandis L.f.). Bila, A., Lindgren, D., & Mullin, T. Silvae Genetica, 48:109–114, November, 1999.
abstract   bibtex   
Flower and fruit production were used to assess plant fertility in a teak (T. grandis) stand in southern Mozambique. The trees varied in fertility, with the 20% most fertile trees in the stand producing 55% of the gametes. Formulae to calculate inbreeding, group coancestry and status number over generations were derived. Predictions over 10 generations, assuming random mating, showed that inbreeding and group coancestry accumulated rapidly during the first generations while status number decreased. This loss of diversity was hastened by differences in fertility among parents. Inbreeding and relatedness increased, while diversity decreased at a considerably slower rate, when the contributions of one gender were kept constant. An efficient way to reduce the loss of diversity was to collect equal amounts of seeds from each seed parent contributing to the next generation.
