Narrative
Progeny trials were conducted in spaced-plant nurseries, established Aug. 1994, to determine the level of apomixis. A survey of 440 plants showed that 5.2% of plants were variants in the vegetative (pre-flowering) state, 3.6% were heading maturity variants, 0% seedhead variants, 0% miniature plants, and 0% were headless plants. Most variants are a shorter growing plant with more purplish seedheads and a shorter culm length. Only about 2% of plants are a taller growing, lighter green variant. These variant plants do not have a 'common type' appearance, but appear similar to an improved variety. Culms on these taller variants extend 2 or 3 cm above the majority plant form. Spaced-plant apomixis rate averages 90% but varies from 85%-95% and above, depending on growing conditions.
