| 0 | PI 592742 | 'USU-Apogee' | Triticum aestivum L. subsp. aestivum | Utah, United States | NSGC |  | | 1996 | DEVELOPED | 1996 | | | | | Cultivar | Hard red spring wheat. Dwarf developed for high yields in controlled environments. Selected for short height, high yield, and resistance to calcium-induced tip necrosis. Extremely fast development rate. Heads emerge 21 days after emergence in continuous light with a constant 25 C temperature. Small flag leaves (14 to 20cm long depending on temperature during development). Close correlation between flag leaf size and head size (seeds per head) in yield trials. Resistant to the severe leaf tip necrosis that occurs in rapid growth conditions, particularly continous light. Leaf tip necrosis (top 30% of the leaf) is associated with calcium-deficiency. Consistently outyields all other full dwarf (less than 0.5 m tall) cultivars tested. In warm temperature conditions (constant 23 C) the yield advantage is about 30%. | 1517622 | PI 592742 |
