Screening of common bean (Phaseolus vulgaris L.) cultivars against root-lesion nematode species

In this study, screening of 15 Phaseolus vulgaris cultivars and genotypes (Zülbiye, Kınalı, Perla, Kwintus, Özayşe, Tokat Sırık, Musica, Şelale, Nadide, Gina, Serra, Karabağ, Funda, and Lepus) and 1 Pisum sativum cultivar (Araka) for host suitability to 4 rootlesion nematodes, Pratylenchus thornei, P. crenatus, P. neglectus, and P. penetrans, was carried out in 2010 and 2011 under controlled conditions. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2014) 38: 455-461 © TÜBİTAK doi:10.3906/tar-1309-18 http://journals.tubitak.gov.tr/agriculture/ Research Article Screening of common bean (Phaseolus vulgaris L.) cultivars against root-lesion nematode species* 1, 1 1 2 3 Mehmet Ali SÖĞÜT **, Fatma Gül GÖZE , Tufan ÖNAL , Zübeyir DEVRAN , Muhammet TONGUÇ 1 Department of Plant Protection, Faculty of Agriculture, Süleyman Demirel University, Isparta, Turkey 2 Department of Plant Protection, Faculty of Agriculture, Akdeniz University, Antalya, Turkey 3 Department of Agricultural Biotechnology, Faculty of Agriculture, Süleyman Demirel University, Isparta, Turkey Received: 04.09.2013 Accepted: 30.10.2013 Published Online: 27.05.2014 Printed: 26.06.2014 Abstract: In this study, screening of 15 Phaseolus vulgaris cultivars and genotypes (Zülbiye, Kınalı, Perla, Kwintus, Özayşe, Tokat Sırık, Musica, Şelale, Nadide, Gina, Serra, Karabağ, Funda, and Lepus) and 1 Pisum sativum cultivar (Araka) for host suitability to 4 rootlesion nematodes, Pratylenchus thornei, P. crenatus, P. neglectus, and P. penetrans, was carried out in 2010 and 2011 under controlled conditions. The experiment was set up in a completely randomized block design with 7 replicates. Approximately 1000 adults + juveniles + eggs of root-lesion nematodes in 10 mL of distilled water were inoculated around the base of each bean seedling. The experiments were harvested after a 10-week duration. Nematodes were extracted from soil and roots by modified Baermann funnel technique and counted under a light microscope. Common bean cultivars and genotypes showed differences in host suitability in the 4 root-lesion nematodes. Pratylenchus penetrans reproduced on Zülbiye, Kınalı, Nadide, Gold Nectar, Karabağ, and Funda. Additionally, P. penetrans had a reproduction index value of slightly higher than 1 on Tokat Sırık, Şelale, and Serra. However, Gina, Musica, Perla, Kwintus, and Özayşe showed poor .
