Negligible information is available in published literature on agronomic traits of perennial Cicer species. The characterization of certain perennial chickpea species conducted in this project will contribute information on their potential for domestication. In the summer of 2004 descriptive data was collected on 23 perennial Cicer accessions composed of 8 different species. Each unreplicated plot contained 2 to 22 plants of each accession with a mean of 9 plants. The nursery was established over three years, in 2001, 2002 and 2003. Measurements of plant height and width were taken along with flowering data, pod size, number of seeds per pod, and yield. Photos where taken of the flower and pod of each species and made available on the Germplasm Resources Information Network (GRIN http://www.ars-grin.gov/npgs). Seeds from each accession were harvested between June and until the middle of September. Seeds collected from each species where characterized according to international descriptors for chickpea published by the International Board for Plant Genetic Resources (1993). There was a great amount of diversity between the accessions in flowering dates, flowering period, flower color, seed size, seed shape, seed color, seed weight, plant size and plant morphology. All accessions shattered seed and shed their pods. Plants that were transplanted in the 2003 did not produce seed in 2004. A replicated (RCBD) study was planted in 2005 in two locations. Eighteen accessions of eleven species were planted in Pullman, Washington and ten accessions of nine different species were planted at The Land Institute, Salina, Kansas.
