Detection of the Mi-1.2 gene for resistance to root-knot-nematode (Meloidogyne javanica (Treub, 1885) Chitwood) in tomato by SCAR marker, Mi23
Abstract
Root-knot nematodes have wide range of host plants and cause important yield looses in many crop plants. The resistance gene Mi was introduced to the cultivated tomatoes from wild tomato species Solanum peruvianum in 1940. The gene confers resistance to Meloidogyne arenaria (Neal, 1889) Chitwood, Meloidogyne incognita (Kofoid & White, 1919) Chitwood and Meloidogyne javanica (Treub, 1885) Chitwood. Present study was carried out in Plant Protection Research Institute of Adana in 2010. In the study tomato plants were inoculated by M. javanica (1000 larva per plant) and resistance features of the genotypes were screened by classical method. Furthermore those tomato genotypes were screened for their resistance as susceptible, homozygot or heterozygote resistant by using REX-F1-REX-R2 and Mi23F-Mi23R specific primers According to the classical tests results the root-gall index values were determined as lower than 2 in resistant plants and higher than 2 in susceptible ones. Reproduction factors were observed 0 and more than1 in resistant and susceptible plants respectively. The data showed a clear correlation between classical screening and the used of DNA markers. It was concluded that those markers could be used in marker assisted selection for M. javanica resistance breeding.
