Technical Abstract: Growers would like to plant sugarbeets as early as possible, while the ground is cold, to maximize the length of the growing season. Experiments were conducted to examine heritability of low temperature germination. Seeds from 10 entries were incubated in water at 5 degrees C with shaking and examined daily for radicle protrusion from seed. Germinated seeds were recorded and planted in peat pots for seed multiplication. Results showed differences between entries, with obsolete commercial hybrids showing highest germination (e.g. US H20 & ACH185), overall and within 10 days of immersion, with the exception of SR96. Genetic variability for low temperature germination, if it exists, will allow breeding of hybrids suited for early planting.
