Abstract

This experiment was carried out in order to evaluate eight different populations of marigold and to introduce the superior population in saline water conditions and in the form of a completely randomized block experimental design with three replications at the Pardisan Agricultural Research Station of Qom in the years 2017-2021. Morphological traits and yield components of seedlings were measured during two years. The resulting data were subjected to composite variance analysis and mean comparisons. Based on the results, a significant difference was observed between the populations under investigation in terms of all traits at the level of 5% error probability. In 2019, the highest height of seedlings, crown diameter and number of buds per plant were observed in Kashan 1 population and the highest freshness of seedlings was observed in Baluchistan population. . In this year, the longest and shortest length of flowering period was observed in Fars 2 and Kashan 1 populations, respectively. In 1400, the highest seedling height and canopy diameter were observed in Kashan populations 2 and 1. The highest number of buds was recorded in Balochistan and Kashan 2 populations. In terms of the weight of the whole flower and the freshness of the seedlings, no great variation was observed between the populations. Only 32 days after the beginning of the new year, flowering began in the communities of Kashan 1 and Baluchistan. In total, the populations of Kashan 1 and 2 were recommended for the development of cultivation in the saline lands and water.
