Summary

Fourth and fifth generation inbred lines of horse and tick spring beans were used for pollination studies.

Treatments included tripping; emasculation followed by self- or cross-pollination at both the bud and mature flower stage; self-pollen rubbed on to the stigma; and the flower truss left undisturbed. Treatment means showed that there was no significant difference between leaving the flower truss undisturbed and tripping, but all other treatments differed significantly (P = 0·01) from these two. There was no difference in number of seeds set per flower between self- or cross-pollination following emasculation.

Tick inbred lines set more seeds per flower over all treatments than horse inbreds. Differences were seen between tick and horse inbreds when the flower truss was left undisturbed; some tick inbreds set seed, but no seed was set on the horse inbreds. An association between seed size and autofertility is suggested.

Results from the horse inbreds were in agreement with previous pollination studies on inbred lines of winter beans. The implications of these studies to plant breeding are discussed.
