Özet
The objective of this study was to determine which resistance genes to the rice blast pathogen (Magnaporthe grisea) were effective in the field in Turkey in 2011 and 2013, in order to determine the most promising genes for use in resistance breeding program. In 2011, 21 monogenic lines in the genetic background of 'Lijiangxintuanheigu' (LTH) targeting 16 different resistant genes, 1 line harbouring P140 gene together with susceptible checks 'LTH 'CO39', and local susceptible checks 'Diyarbakir yerli' and 'Sariceltik', and additional some cultivars were tested in 10 locations. In 2013,29 monogenic LTH lines targeting 24 blast resistant genes and 2 lines harbouring the Pi40 gene were tested in 2 locations. We observed that, Pi1, Pi7, Pi9, Pi12, Pi20, Pi40, Pib, Pik-h, Pik-m, Pik-p, and Piz-5 genes provided resistance in all rice locations tested. Moreover, Pi5(t), Pita, Pita-2, Pit, and Pi-z provided moderate resistance in Turkey. Pi7, Pi9, Pi12, Pi20, Pi40, Pib, Pik-h, Pikm, Pik-p, and Piz-5 genes can be used alone or in different combinations. To obtain durable resistance to rice blast in Turkey, we recommend breeding cultivars containing different stacked combinations of afore mentioned genes. Pi1, P15(t), Pita, Pita-2, Pit, and Piz genes, when added to such stacks, could further improve blast resistance in rice cultivars for Turkey.
