Genetic Diversity Of Wilt And Root Rot Pathogens Of Chickpea, As Assessed By Rapd And Issr, Harun Bayraktar, F. Sara Dolar
Genetic Diversity Of Wilt And Root Rot Pathogens Of Chickpea, As Assessed By Rapd And Issr, Harun Bayraktar, F. Sara Dolar
Turkish Journal of Agriculture and Forestry
Intra- and interspecific polymorphisms among fungal pathogens that cause wilt and root rot on chickpea were investigated by using 30 RAPD (random amplified polymorphic DNA) and 20 ISSR (inter-simple sequence repeats) primers. UPGMA (unweighted pair group method with arithmetic average) cluster analysis of RAPD and ISSR datasets using Dice's coefficient differentiated all fungal isolates from each other and revealed considerable genetic variability between the isolates. The isolates that were not easily separable using morphological characteristics were classified again according to their branching in dendrograms. A partial correlation was observed between cluster analysis and geographic origin of Fusarium solani isolates. Additionally, …

Determination Of Pathogenic Variability Of Didymella Rabiei, The Agent Of Ascochyta Blight Of Chickpea In Turkey, Muharrem Türkkan, F. Sara Dolar
Turkish Journal of Agriculture and Forestry
Pathogenic characterization of 64 Didymella rabiei isolates obtained from 5 different regions in Turkey was determined with a set of 7 different chickpea cultivars (ILC 1929, F8, ICC 1903, ILC 249, ILC 482, ILC 3279, and ICC 3996). All the isolates were classified into both 3 pathotypes and 6 physiological races. Of the isolates used in this study, it was determined that 38 (59.4%) belonged to pathotype I, 3 (4.7%) to pathotype II, and 23 (35.9%) to pathotype III. Pathotypes I and III were determined in 5 regions of Turkey including the Mediterranean, Aegean, Southeastern Anatolia, Central Anatolia, and Black …
