| 0 | PI 639724 | 'Choptank' | Triticum aestivum L. subsp. aestivum | Maryland, United States | NSGC |  | | 2005 | DEVELOPED | 2004 | | 39.03483170, -76.90747390 | | | Cultivar | Soft red winter wheat. Early-heading, short wheat that has performed well in DELMARVA. Has excellent resistance to powdery mildew. In four years of testing it has consistently ranked among the top yielding genotypes for grain yield, similar to Sisson and SS550 in MD. In VA, average grain yields of 80 bu/ac were similar to those of McCormick and Sisson, and 4 to 6 bu/acre higher than Pioneer 2580 and USG3209. In DE trials it ranked high for grain yield as well. Average test weight was 56.6 lbs/bu, slightly higher than Sisson and SS550 but lower than McCormick and Roane. Milling quality is good and superior to that of Roane and similar or slightly better than its sister line SS 550. Grain of Choptank produces more flour than Roane and Pioneer 2580 and is similar to SS 550 in texture but softer than Roane and Coker 9663. Baking quality is excellent and superior to stringent checks such as Pocahontas or Sisson. Flour absorbs less water and produces larger cookies than Roane, Pocahontas and Sisson. | 1678718 | PI 639724 |
