Interpretive Summary: Chickpeas are an important rotational crop in the U.S. Pacific Northwest; however, the occurance of ascochyta blight in the region has devastated crops and made production uneconomical. The use of fungicides can alleviate some of the effects of the disease, but applications are costly and must be repeated. The development of resistant varieties, such as Dwelley, has made eit possible to reliably produce the crop without the added expense of fungicide applications. Dwelley is resistant to the disease and has better yields and seed quality when compared to previously grown varieties. Dwelley has made it possible to produce the crop without the devastating effects of ascochyta blight.

Technical Abstract: Chickpeas are a relatively new to the cropping systems of the U.S. Pacific Northwest. However, recent outbreaks of ascochyta blight have caused devastation to currently available varieties and in many cases severe crop losses. Because of this problem it has become necessary to develop resistant germplasm in order to reduce the risk of growing the crop. 'Dwelley' is a large seeded "Kabuli" type variety developed and released i 1994. Dwelley originated as an F7 selection from a cross made in 1988 between Surutato-77 and FLIP85-58. The selection was identified as resistant to blight in the ascochyta blight screening nursery established a Pullman, WA. In further tests for resistance to blight and in yield trials Dwelley continued to outperform the standard check varieties. Dwelley has a unifoliate leaf structure that differs from the fern leaf structure that is typical of chickpea cultivars such as 'UC-5', 'UC-27' and 'Spanish White'. Seeds of Dwelley weigh 58 grams per 100 seeds. The light cream colored seeds of Dwelley are desired by domestic processors and by exporters. Samples of Dwelley are available on request.
