Technical Abstract: In Michigan, an average of 60% of sugar beet seeds germinate and survive to harvest under field conditions, and planting occurs in early spring when soil temperatures approach 55 deg F (~12 deg C). Large temperature deviations above or below that may induce heat or cold stress that may be lead to a reduction in germination and consequently reduced crop productivity. Under low temperature, only four germplasms showed 50% or greater germination by 96 hours. Interestingly, the best cold-germination germplasm was SP7322, the pollen parent of the former widely grown ‘US H20’ hybrid. Other accessions in this set included SR w/EL (EL-A024974), 04B134 (Bvm nema / sel Bay City) (EL-A024984), and 95HS2/sel x 07-5E (EL-A027013). These four genotypes have been introduced into germplasm enhancement program for cold tolerance genotypes.
