Development of Multiple Stress-Resistant Kabuli Chickpea Germplasm for Diverse Growing Regions.https://hdl.handle.net/20.500.11766/68745Chickpea (Cicer arietinum) is an important crop in dry areas of the world. The major production challenges of chickpea production are Ascochyta blight (AB), wilt/root rot, cold, and drought. ICARDA is mandated to develop elite germplasm resistant to key production challenges of spring and winter-planted chickpea. The wilt/root rot was assessed by recording the percentage of plants showing symptoms of wilting, while the AB was evaluated using a 1-9 disease rating scale where 1 is highly resistant, while a rating of 9 is highly susceptible. ICARDA chickpea breeding program follows the pedigree breeding method to develop multiple stress resistant/tolerant germplasm targeting demands of National Partners in South Asia, Sub-Saharan Africa, and the Mediterranean regions. In this abstract, we present the outcomes of crosses made in 2014 to develop wilt/root rot, and AB resistant chickpea genotypes. A total of 106 crosses were derived from 212 parents and F1 seeds were harvested and planted as F2. A total of 613 selected plants (F3) were evaluated in the wilt/root rot sick pilot at Terbol station, Lebanon. About 62% of progenies with < 15% mortality were retained and screened for AB. A total of 383 lines were selected AB resistant. Only 144 F5 lines were selected from the second round of wilt/root rot screening with a mortality of < 15%. Finally, 48 genotypes with multiple resistance were shared with the national partners.JPGCopyrighted; Non-commercial educational use onlymultiple stress resistancePosterOpen access
