ESPECHE, Clara M. et al. TUC G-470: new Kabuli type chickpea cultivar with large caliber seeds developed by the Estación Experimental Agroindustrial Obispo Colombres of Tucumán, Argentina . Rev. ind. agric. Tucumán [online]. 2021, vol.98, n.1, pp.41-46. ISSN 1851-3018.

Chickpea (Cicer arietinum L.) is a legume grown in the tropics and in the Mediterranean regions of the world. In Argentina, it is produced from the latitude 20° to 33° south, where chickpea represents a valid alternative for area with irrigation as for subhumid-humid regions, such as the foothills in Northwestern Argentina (NWA). Until a few years ago, availability of cultivars was scarce; growers only had saucos populations and cultivars Chañarito S- 156 and Norteño. In the last five years other cultivars were released: Kiara INTA-UNC Felipe INTA-UNC, and TUC 464 and TUC 403 from the Estación Experimental Agroindustrial Obispo Colombres (EEAOC). The release of new cultivars will be decisive to support the development of this crop in Argentina, because growers will have increased options for each region. The objective of this paper is to describe the development of a new Kabuli type chickpea cultivar with large caliber seeds. The EEAOC introduced 36 pure stable lines from the International Center for Agricultural Research in the Dry Areas (ICARDA), Syria. From 2009 through 2011 these lines were evaluated in La Ramada, Tucumán province, on the basis of their adaptation, plant structure, disease reaction, and grain quality. Six lines were selected which were further evaluated in Comparative Yield Tests (CYT) from 2012 through 2016 in different locations. Blanco Lechoso and Mexicano were the local controls included. Results from these comparative tests indicated that one line exceled, with higher yields than the controls in the majority of the cases. It has large caliber and light colored seeds, which makes it different from the other cultivars released by the EEAOC, TUC 403 and TUC 464, which are classified within the kabuli grouping. The new cultivar, denominated TUC G-470, has a cycle of 146 days, an average yield of 1.300 kg/ha, and is susceptible to Fusarium oxysporum f. sp. ciceri and sensitive to cold weather, a characteristic of this type of chickpea. It has grains with excellent commercial quality and a 100-seed weight of 50 g, characteristics which will allow entering into high prize markets.
