Interpretive Summary: ‘Dylan’ chickpea (Garbanzo) was developed and released based on its resistance to ascochyta blight, a devastating disease of chickpea crops. The new variety is also earlier to flower and mature when compared to varieties such as Dwelley and Sierra which is a distinct advantage for regions of the U.S. with relatively short growing seasons. Seeds of Dylan are large and very light cream colored. These quality traits are appealing to domestic canners of garbanzos a product used extensively in salad bars in the U.S. and should be readily accepted in international markets for large seeded chickpeas.
Technical Abstract: ‘Dylan’ (Reg. no. , PI ) is a large seeded kabuli type chickpea (Cicer arietinum L.) developed by the USDA-ARS in cooperation with the Washington Agricultural Research Center, Pullman, Washington, the Idaho Agricultural Experiment Station, Moscow, Idaho, the North Dakota Agricultural Experiment Station, Fargo, North Dakota and the California Agricultural Experiment Station, Davis, California and released in 2005. Dylan has good resistance to ascochyta blight [caused by Ascochyta rabiei (Pass.) Labrousse; syn. Phoma rabiei (Pass.) Khune & J.N. Kapoor], a disease that has devastated chickpea crops in the U.S. Pacific Northwest from 1983 to 1992 and continues to cause disease in chickpea production regions. Dylan originated as an F8 selection from the cross ‘Blanco Lechoso’/‘Dwelley’ made in 1994. Blanco Lechoso is a large white-seeded Kabuli type cultivar introduced into the U.S. from Mexico and Dwelley (PI 598079) is a unifoliolate Café Kabuli type cultivar with resistance to ascochyta blight. From the F1 to F8, progenies from the cross were advanced by the pedigree method with selection for seed size and color from the F3 to the F8. Dylan has a fern leaf structure that differs from the unifoliolate leaf structure typical of Sanford, Dwelley and Sierra. Plants of Dylan are branched at the base and have an indeterminate flowering habit. Pods are rhomboid-ellipsoid and have glandular trichomes, which give them a pubescent appearance. Pods of Dylan have one and occasionally two seeds. Seeds of Dylan average 56.8 grams per 100 seeds. Seed size is similar to Sierra and slightly larger than Dwelley. Light-cream colored seeds of Dylan are lighter than Sierra and Dwelley.
