TAILIEUCHUNG - Selection of chickpea (Cicer arietinum L.) genotypes for resistance to ascochyta blight Ascochyta rabiei (Pass.) Labr., yield and yield criteria

Ascochyta blight, caused by Ascochyta rabiei (Pass.) Lab., is the most important disease in the chickpea (Cicer arietinum L.) in many countries, including Turkey. Efforts to control the disease were made using host-plant resistance as the most efficient and economical way. | Turk J Agric For 27 (2003) 277-283 © TÜB‹TAK Selection of Chickpea (Cicer arietinum L.) Genotypes for Resistance to Ascochyta Blight [Ascochyta rabiei (Pass.) Labr.], Yield and Yield Criteria Cengiz TOKER*, Hüseyin ÇANCI Department of Field Crops, Faculty of Agriculture, Akdeniz University, 07070 Antalya - TURKEY Received: Abstract: Ascochyta blight, caused by Ascochyta rabiei (Pass.) Lab., is the most important disease in the chickpea (Cicer arietinum L.) in many countries, including Turkey. Efforts to control the disease were made using host-plant resistance as the most efficient and economical way. A total of 41 exotic genotypes were evaluated for resistance to A. rabiei and also yield and yield criteria near Antalya in the west Mediterranean region of Turkey in the 2000-2001 and 2001-2002 seasons. After every 2 test lines, the susceptible check ILC 263 was sown. When the susceptible check was completely killed by ascochyta blight, blight severity was scored on the 1 to 9 class scale. FLIP 95-53C and FLIP 95-68C were selected for their high seed yield. FLIP 97-74C and FLIP 95-53C were selected for their high biological yield. FLIP 98-177C had the largest seeds and was selected for its high seed yield and harvest index. All of them were also resistant to ascochyta blight. It was assumed that the selected genotypes could be released directly for commercial production or be used in breeding programs.
