Interpretive Summary: The genus plantago comprises a number of species that have value as a source of soluable fiber in medicinal andiindustrial applications. This study screens a collection of 8 diverse species of Plantago that were collectred within their respective native ranges that were screend for drought tolerance in inder two watering regimes in 3 locations. Acessions used in this study were also genotyped at both SSR and ISSR markers. Association of the alleles identified with these markers were used for association and genetic predicttion linear mixed models aimed at improving breeding advances in this important medicinal crop.

Technical Abstract: Genetic analysis of medicinal plant lags behind other well-known plant species due to limited genomic information. The genus of Plantago covers a large number of species with medicinal and industrial value. Literature shows in most of studies related to genetic and breeding Plantago, low number of species and markers have been used in single year/location /environment that affect reliability of the results. In our study we presented the data and results in three areas. One is genetic variation for seed and mucilage traits under different environmental conditions in eight plantgao species. The other is assessment of drought risk index of plantago species tested over 3 locations and at least two years. Lastly, analysis of association of large number of alleles in two marker systems (ISSR and SSR) with seed and mucilage traits for use in marker associated selection programs. Here in this study, we tried to collect 30 diverse accessions belonging to eight plantago species from different geographical regions in Iran to be tested in 11 experiments. In view of statistical approaches used, we used best linear unbiased predictions for the genotypic values (BLUP), which have not almost used in previous studies in plantago.
