Abstract

Chickpea (Cicer arietinum L.) cultivar New Hope (Reg. No. CV-315, PI 679590), a large, cream-colored, kabuli type, is a F_8:13 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.
