N2  - 0ion for rapid seedling emergence at 4&#176;C had no effect on plant growth. Pollen selection at low temperature improved subsequent plant growth at lowtemperature. The dry weight ratio of plants grown at 13/4&#176;C to that at 18/13equent plant growth at lowtemperature. The dry weight ratio of plants grown at 13/4/night) at 26 days after emergence, whereas selection for rapid seedling emergence at 4&#176;C had no effect on plant growth. Pollen selection at low temperature improved subsequent plant growth at lowtemperature. The dry weight ratio of plants grown at 13/4&#176;C to that at 18/13&#176;C was higher in progenies derived from fertilisation at 10/2rature.

The dry weight ratio of plants grown at 13/4&#176;C to that at 18/13&#176;C was higher in progenies derived from fertilisation at 10/2&#176;C than those from 18/13days after emergence, whereas selection for rapid seedling emergence at 4&#176;C had no effect on plant growth.

The ability to use pollen selection in combination with pedigree selection for low potassium leakage should increase genetic gain of plant dry weight at low temperature in segregating populations.
