In order to investigate the relationship between quantitative traits and ISSR markers, an experiments were carried out under farm and laboratory conditions at Zanjan University. In this experiment, 20 primers of ISSR marker were used and the agronomic traits (including flower number, fresh weight of Stigma, fresh weight of flower, dry weight of Stigma, dry weight of flower, stigma length, saffron yield, corm number, feresh and dry weight of corm, number of leaf, leaf length, leaf width, leaf area, leaf dry weight, biomass, harvest index), physiological traits (transpiration rate, stomatal conductance, photosynthesis) and secondary metabolites (picocrocin, Safranal and Crocin) were measured during the growing season. Three primers of total did not amplified. 17 ISSR primers amplified 133 loci among 20 saffron ecotypes, with an average of 7.82 loci per primer. The highest number of alleles were for the I-8 primer (15 alleles).

Each year a large amount of saffron petals which make up a significant proportion of saffron flowers are discarded as waste while this part of the flower also contains compounds such as phenol, anthocyanin, flavonoid and antioxidant properties. Two separate experiments were conducted using randomized complete block design with three replications in order to evaluate secondary metabolites, total phenol content and antioxidant capacity of petals in eight saffron populations under normal and once irrigation conditions at the research farm of university of Zanjan on three year old saffron plants. In order to measure and determine secondary metabolites, total phenol content and antioxidant properties of saffron petal extract, UV-Visible Metering Spectra, folin-Ciocalteu and DPPH were used, respectively. Combined analysis of variance under normal and once irrigation conditions showed that the difference between secondary metabolites and antioxidant properties was not significant in the two irrigation conditions. While, total phenol content was significantly higher under the once irrigation condition, the Torbat-e-jam population had highest total phenol content (86.66 mg gallic acid per gram of methanolic extract) under this condition. In both irrigation conditions, the evaluated populations exhibited suitable amounts of picocrocin, safranal, phenol and antioxidant properties which can be considered to be of use for us in the food, pharmaceutical and chemical industries.

In order to investigate the effective traits on yield of saffron ecotypes, a study was carried out as a split plot in time based on randomized complete block design with three replications in the research farm of Zanjan University during the growing seasons of 2013-2015. Eighteen saffron ecotypes were studied in this experiment. The traits of number of flowers, fresh weight of flowers, fresh weight of stigma, dry weight of flowers, dry weight of stigma, stigma length and dry stigma yield of saffron were measured. The results indicated that there were significant differences among all studied traits of ecotypes except for stigma length. The correlation matrix revealed that the number of flower and dry weight of stigma had a positive and highly significant correlation with dry stigma yield (r= 0.99 and 0.70, respectively). Analysis of stepwise regression and path analysis showed that the traits of number of flowers, dry weight of stigma and dry weight of flowers were the most effective traits on dry stigma yield. Therefore, these traits can be used to achieve a higher stigma yield.
