Self-incompatibility and inbreeding depression in Parkia biglobosa

by Kristin Marie Lassen et al.

Parkia biglobosa

This paper presents results from a trial with controlled self- and cross-pollination of the semi-domesticated fruit tree, Parkia biglobosa (Fabaceae). We used eight trees acting as fathers and mothers in a diallelic cross.

Due to over-exploitation, low regeneration and reduced rainfall the density of P. biglobosa trees is declining in the landscapes in West Africa, and we expect more self-pollination because of increased distances among trees. Since P. biglobosa is known as a mostly outbreeding species, we wanted to reveal a potential effect of increased selfing by comparing fruit set and seed germination after self- and cross-pollination.
