In this study, the effect of Vesicular Arbrbusular Mycorrhizae (VAM) on the ex vitro hardening of marigold was investigated. A protocol was generated for ex vitro hardening of in vitro raised plantlets using VAM consortia (Glomus intraradices, Glomus mosseae and Scutellospora spp.) in different media mixtures, and their effect was observed on plant survival and growth. Highest percent survival (), maximum plant height ( cm), maximum plant spread ( cm), maximum stem diameter ( cm), maximum shoot fresh weight ( g), maximum root fresh weight ( g), maximum leaf length ( cm), maximum root length ( cm) and maximum leaf width ( cm) were observed in treatment comprising of Soil + Vermicompost (3:1) + 20 g VAM consortia, Followed by plant survival, cm plant height, cm plant spread, cm stem diameter, g shoot fresh weight, g root fresh weight, cm leaf length, cm root length, and cm leaf width in treatment comprising Soil + Vermicompost (1:1) + 20 g VAM consortia. | Effect of vam on EX vitro hardening of doubled haploid line of marigold (Tagetes erecta L.) variety local orange
