Role of Different Rootstocks on Yield and Resistance for Fusarium oxysporium, Verticillium dahliae and Meloidogyne incognita in Grafted Peppers

Abstract

The aim of this study was to determine the effects of different rootstocks on yield characteristics and resistance capability against to Fusarium wilt, Verticillium wilt and Meloidogyne incognita in pepper cultivation. 'California Wonder' and 'Kandil' bell pepper varieties were grafted on 'Snooker F-1', 'Dro F-1', NGS and NGC rootstocks in the experiment. Nongrafted and selfgrafted plants were used as control. Grafted plants were cultivated in open field conditions with sterilized growth media. The experiment was conducted in randomized split plots design with three replications. Yield was increased significantly by rootstocks in infected plots and it was higher than control plants in uninfected plots. The highest yield was obtained from 'Kandil' x 'Dro F-1' combination in Fusarium oxysporium experiment, 'Kandil' x 'NGS' combination in Verticillium dahlia experiment and 'California Wonder' x 'Snooker F-1' combination in Meloidogyne incognita experiment. Study showed that using of grafted plants was more effective than nongrafted and selfgrafted plants for obtaining resistance against to Fusarium oxysporium and Meloidogyne incognita by depending on rootstocks but, not against to Verticillium dahliea.
