Evaluation location: Colorado, United States
A total of 477 accessions were evaluated in 2002 (238 accessions) and 2003 (239 accessions) at the Southwestern Colorado Research Center in Yellow Jacket, CO. They were planted in 30-in. rows and 3.75-in seed spacing with a Monosem Planter on 24 May in 2002 and 23 May in 2003. Each accession was planted in a 60-ft single row with no replication. The soil at the test site is a Wetherill loam (fine silty, mixed, superactive, mesic Aridic Haplustalfs). The plot area was irrigated with a line-source sprinkler system similar to the one described by Hanks et al. (1976). The amount of irrigation water decreased with the distance away from the sprinkler line. For practical purposes, we only distinguished two irrigation levels, wet and dry. Total precipitation from May to August was 1.01 in. in 2002 and 4.65 in. in 2003 compared to a 30-year average of 5.13 in. There was good soil moisture at planting in both years. Chickpea accessions were planted on fallow ground in 2002 and 2003 (different field each year).
