BC0894-2, an advanced chipping selection, performed best at the narrow spacing as expected. The widest spacing provided maximum yield and grade for the advanced russet selection CO85026-4. Producers should adjust within-row spacing for this clone by desired end use or premium price within the market place. 1999 Development of cultivar specific management profiles for new potato cultivars is the primary aim of this research project. Approximately twenty-four advanced selections were evaluated in cultural and physiologically related studies in 1999.
Several trials are standard for advanced selections, prior to release and naming.
These include investigations observing growth analysis, responses to differing fertility regimes, and plant population. Information gleaned from these inquiries has direct applicability in development of producer management strategies. Results from the 1999 plant population study are presented here. All selections were included in the 1998 trial. Cultural practices typical of the growing area were utilized, including planting on 34-inch rows and the utilization of sprinkler irrigation.
