This study was funded by CGIAR Research Program on Grain Legumes at ICRISAT and by core research grant of IIPR, PAU and IARI abstract: Chickpea (Cicer arietinum L.) is known to be sensitive to many herbicides and, therefore, choices for using post-emergence herbicides for weed control are limited. The present study was aimed at identifying sources of tolerance to two herbicides with different modes of action (imazethapyr—amino acid synthesis inhibitor; and metribuzin—photosynthesis inhibitor) for use in breeding herbicide tolerant cultivars. Screening of 300 diverse chickpea genotypes (278 accessions from the reference set and 22 breeding lines) revealed large genetic variations for tolerance to herbicides imazethapyr and metribuzin. In general, the sensitivity of the genotypes to metribuzin was higher compared to that for imazethapyr. Several genotypes tolerant to metribuzin (ICC 1205, ICC 1164, ICC 1161, ICC 8195, ICC 11498, ICC 9586, ICC 14402 ICC 283) and imazethapyr (ICC 3239, ICC 7867, ICC 1710, ICC 13441, ICC 13461, ICC 13357, ICC 7668, ICC 13187) were identified, based on average herbicide tolerance scores from two experimental locations each. The herbicide tolerant lines identified in this study will be useful resources for development of herbicide tolerant cultivars and for undertaking genetic and physiological studies on herbicide tolerance in chickpea. date: 2013 date_type: published publication: Agronomy volume: 3 publisher: MDPI Publishing pagerange: 524-536 refereed: TRUE issn: 2073-4395 official_url: http://www.mdpi.com/2073-4395/3/3/524 related_url_url: http://scholar.google.co.in/scholar?as_q=%22Large+Genetic+Variability+in+Chickpea+for+Tolerance+to+Herbicides+Imazethapyr+and+Metribuzin%22&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&btnG=&hl=en&as_sdt=0%2C5 related_url_type: pub funders: Consultative Group for International Agricultural Research funders: Indian Institute of Pulses Research funders: Punjab Agricultural University funders: Indian Agricultural Research Institute projects: CGIAR Research Program- Grain Legumes projects: Core Research Grant citation: Gaur, P M and Jukanti, A K and Samineni, S and Chaturvedi, S K and Singh, Sarvjeet and Tripathi, S and Singh, Inderjit and Singh, G and Das, T K and Aski, M and Mishra, N and Nadarajan, N and Gowda, C L L (2013) Large Genetic Variability in Chickpea for Tolerance to Herbicides Imazethapyr and Metribuzin.
