BREEDING SYSTEMS IN NEW ZEALAND PLANTS
4. SELF-STERILITY IN PENTACHONDRA PUMILA

E. J. Godley

Botany Division, Department of Scientific and Industrial Research, Christchurch

Abstract Pentachondra pumila (Epacridaceae) has small white salverform flowers in which Ihe stamens and stigma are included in the tube. Although autogamous self-pollination is the rule, it was found that the fruit set on four plants self-pollinated by hand was only 0, 0, 3, and 16.6%, and some fruits had a reduced seed number. In contrast experimental crosses between plants were highly fertile. The results are consistent with control of fertility by an S-allele system. Insects are probably the natural crossing agents, but the process remains unobserved.
