Colorado Winter Wheat Variety Descriptions and Characteristics

Colorado State University, with the support and cooperation of the Colorado wheat industry, conducts annual dryland (UVPT) and irrigated (IVPT) variety performance trials to obtain unbiased and reliable information for Colorado wheat producers to make better wheat variety decisions. Good variety decisions can return millions of dollars to Colorado wheat producers.

Dryland planting conditions in fall of 2003 were generally poor due to dry soil conditions. These conditions led to extremely narrow planting windows at most locations to plant and obtain good stands. Inadequate fall and winter precipitation was followed by a dry spring (with the exception of some timely rains in April) and moderate drought stress conditions at many locations. The spring drought was aggravated by very short sub-soil moisture conditions. Uneven and incomplete fall emergence was observed at Lamar, Cheyenne Wells, Genoa, and Orchard and led to these trials being abandoned (Genoa and Orchard) or yield data that were too variable to be useful for variety comparisons (Lamar and Cheyenne Wells). The trial at Walsh was lost to severe hail damage on the eve of harvest and the trial at Burlington was lost to spring drought and a severe spring freeze at flowering in mid-May. Rains beginning during the third week in June and continuing into early July provided very moderate temperatures during grain filling as well as leading to serious weed pressure in trials and production fields alike. The rain made it difficult to get into fields for harvest and led to reports of sprouting in both hard white and hard red varieties.

Russian wheat aphid pressure was high again this year, especially in east-central and southeastern Colorado. The new Russian wheat aphid biotype, denoted as "biotype B,” overcomes the resistance in all RWA-resistant varieties released to date. This new biotype was found throughout eastern Colorado in 2004 in conjunction with the original RWA biotype (denoted as "biotype A"). Recent findings suggesting that additional biotypes may be present in Colorado and other areas of the Great Plains could present formidable challenges to our entomology and wheat breeding programs. Wheat steak mosaic virus and high plains disease were not problematic in 2004 while barley yellow dwarf virus, due to high greenbug infestation levels, was observed at the IVPT at Rocky Ford. Both leaf rust and stripe rust were identified in late-maturing wheat (due to poor stands) at some locations but infestations were generally very light and too late in the grain filling period to cause significant damage.

The following summary tables of results are designed to disseminate the essential information as quickly as possible to as many people as possible through the wheat industry, popular press, and DTN.
