Varieties selected after entering all criteria will be displayed in descending order based on gross dollars per acre. Generally the most suitable varieties will be listed first. The number of varieties selected is dependant on the criteria selected. If no criteria is entered, all varieties will be selected. It is also possible for no variety to meet the selection criteria. Should that happen, the criteria must be revised to make a selection.

1. Which database do you wish to use?
   Coded Variety data is drawn from American Crystal Sugar Company's Coded Variety Trials. These are replicated research plot trials that are used to approve varieties for sale to American Crystal shareholders. It contains information on both commercial and specialty varieties grown under non-disease, Aphanomyces and/or Rhizomania conditions. Two year mean data for sugar per ton, tons per acre, gross revenue per acre and Cercospora rating, two year data for Aphanomyces rating and one year data for emergence counts are used in the variety selector.

   Grower Practice data is drawn from American Crystal Sugar Company's records of shareholders' commercially grown fields. To prevent incorrect information caused by cross hauling of beets between different fields, the following criteria are used. Fields must be representative, have yields between 12 and 42 tons per acre. Varieties are listed with at least 500 harvested acres. Data for sugar per ton, tons per acre and gross dollars per acre from the most recent year is used in the variety selector. Aphanomyces rating will be taken from the Coded Variety Trial Aphanomyces data.

2. Which location?

   Grower practice data may be selected by individual factory district as well as the Red River Valley. Coded variety data is only available for the entire Red River Valley.

3. What station do you deliver to?

   The freight for the station you selected will be subtracted from the gross dollars per acre for the selected varieties. No freight is subtracted from sugarbeets delivered to a yard.

4. How many miles is it from the field to the station?

   $1.62 per ton + $.161 per ton mile will be subtracted from gross dollars per acre for the varieties selected.

5. Enter severity of Rhizomania symptoms last seen in this field

   Rhizomania is favored by warm, wet soil conditions. Once disease is established resistant varieties are the only practical control option. In fields with severe rhizomania, only diploid varieties should be used

   The most suitable Rhizomania variety will be based upon the percentage of Rhizomania tolerance genes for the varieties and performance in Coded Variety Trials or results from Grower Practice Data.

6. Is Aphanomyces an issue?

   Aphanomyces is a fungal disease that is common in the Red River Valley. It can cause severe stand loss. Lower Aphanomyces ratings are better. If slight is selected, varieties with Aphanomyces Ratings of 4.9 average or below will be considered. If moderate or severe is selected, only Aphanomyces Specialty will be selected. If Aphanomyces is a problem, growers should strongly consider purchasing seed treated with Tachigaren and should consider using only resistant varieties. Be sure to check Cercospora, Fusarium and Rhizoctonia ratings and Rhizomania classification of the selected varieties. The severity of Aphanomyces is greatly dependant on the weather conditions during the growing season. In years that are wet and warm for the entire growing season, severe Aphanomyces can develop in fields that only have a small amount of inoculum.

7. What's the Cercospora Rating?

   The drop down list shows the Cercospora Ratings for the different varieties in descending order. Lower Cercospora ratings are better. Click on the rating you choose. Be sure to check Aphanomyces, Fusarium, Rhizoctonia ratings and Rhizomania classification of the selected varieties.

8. Is Fusarium an issue?

   If Yes is selected, only commercial varieties with Fusarium Resistance Ratings of 5.0 or below will be considered by the Selector. Be sure to check Aphanomyces, Cercospora and Rhizoctonia ratings of the selected varieties

9. Is Rhizoctonia an issue?

   If Yes is selected, only commercial varieties with Rhizoctonia Resistance will be considered by the Selector. Be sure to check Aphanomyces, Cercospora and Fusarium ratings of the selected varieties.

10. Does the field have excessive available Nitrogen?

    Excessive nitrogen reduces sugar per ton and increases sugar loss to molasses. If Yes is selected, only varieties with average or above sugar per ton will be considered by the Selector.

11. Is stand establishment a problem?

    The field emergence ratings from the most recent Coded Variety test are used. If Yes is selected, only varieties with average or above field emergence will be considered by the Selector. There may be factors other than variety causing stand establishment problems.

12. Is your individual grower history above or below factory average for sugar content per ton?

    If below only varieties with average or above sugar per ton will be considered by the Selector.

    Be sure to check the revenue per acre for your selected varieties. Sacrificing revenue per acre for increased sugar can be a poor management decision

13. Is your individual grower history above or below factory average for tons per acre?

    If below is selected, only varieties with average or above tons per acre will be considered by the Selector.

    Be sure to check the revenue per acre for selected varieties. Sacrificing revenue per acre for increased tonnage can be a poor management decision.
