Abstract :This study evaluated seedling traits insert ignore into journalissuearticles values(shoot/root length, fresh and dry weights of shoots/roots, number of leaves, shoot diameter);, phosphorus insert ignore into journalissuearticles values(P); content, mycorrhizal colonization insert ignore into journalissuearticles values(MC);, and relative mycorrhizal dependency insert ignore into journalissuearticles values(RMD); of 21 common bean genotypes inoculated by 4 different arbuscular mycorrhizal fungi insert ignore into journalissuearticles values(AMF); [Glomus intraradices insert ignore into journalissuearticles values(Gi);, Glomus mosseae insert ignore into journalissuearticles values(Gm);, Gigaspora margarita insert ignore into journalissuearticles values(Gim);, and commercial AMF insert ignore into journalissuearticles values(cAMF);] in a growth chamber under controlled growing conditions. With the exception of shoot diameter, inoculated plants had better seedling traits than noninoculated plants. P content of shoot was also higher in inoculated plants than in noninoculated plants. Of the 20 genotypes and Nadide cv. examined, 5 responded positively and 3 responded negatively to inoculation with all AMF types. Great variations in RMD and MC were observed, with the highest RMD and MC in the T120 insert ignore into journalissuearticles values(69.54%); and T71 insert ignore into journalissuearticles values(81.09%); genotypes and the lowest in the V77 insert ignore into journalissuearticles values(1.26%); and V78 insert ignore into journalissuearticles values(31.42%); genotypes. Positive correlations were found between RMD and seedling traits, with the exception of shoot length as well as root length, P content, and colonization. MC was significantly correlated only with P content.
