Urrea, Carlos A. | Muehlbauer, Fred J. | Harveson, Robert M.
Chickpea (Cicer arietinum L.) cultivar New Hope (Reg. No. CV‐315, PI 679590), a large, cream‐colored, kabuli type, is a F₈:₁₃ line obtained from the cross CA9990B1895C/CA9890233W. CA9990B1895C is a F₄ line derived from the cross of FLIP91‐021/ ‘Sanford’. CA9890233W was an F₆ selection from the cross of ‘Blanco Lechoso’/*2/CA188620. New Hope was selected specifically for adaptation to Nebraska growing conditions and for enhanced resistance to Ascochyta blight, a major disease of chickpea caused by Ascochyta rabiei (Pass.) Labr. Under nonfungicide conditions (natural infection), New Hope had significantly lower (P < 0.05) incidence and severity of Ascochyta blight compared with the commercial kabuli cultivars ‘CDC Orion’, ‘Sierra’, and ‘HB‐14’ in 2012, and compared with CDC Orion, ‘CDC Frontier’, Sierra, and HB‐14 in 2015. In both 2012 and 2015, incidence of Ascochyta blight in New Hope was similar to that of resistant germplasm line PHREC‐Ca‐Comp. #1, released in 2011. Across years (2012–2015) and environments (fungicide protected, nonprotected), yield of New Hope did not differ significantly (P > 0.05) from the other cultivars. New Hope exhibits an upright indeterminate growth habit. Plants average 43 cm tall and have excellent lodging resistance. New Hope has a compound leaf structure and white blossoms and flowers 44 d after planting. It is a midseason chickpea maturing 105 d after planting. Seed size meets commercial standards.
