Summary

Measurement of the variation in reproductive characters between genotypes of Phleum pratense showed that inflorescence length had a significant variance and was correlated with seed yield/plant. Genotypes with the longer inflorescences showed a quicker response to a long photoperiod and had a longer period of inflorescence development, and there was an indication that selection for increased inflorescence length might affect the production of leaves. A genetic analysis of a 6 x 6 half diallel cross showed that additive and non-additive effects were evident in the control of inflorescence length under natural conditions, but the non-additive effects were almost entirely suppressed under glasshouse conditions.
