Investigation and selection among native populations of Flixweed (Descurainia sophia) of Khorasan Razavi province for yield and yield components under greenhouse condition

In addition to economic production of crops in various different country's countries, the ability to create vegetation, prevent soil erosion and wind, increase soil organic matter, prevent direct evaporation of soil moisture during the growing season, increase water use efficiency by the plant (Pirkhezri, 2009; Mahdikhani et al., 2015). Due to the characteristics of the crop and its medicinal properties, the diversity of indigenous and local populations and the genetic resources of this plant in different habitats, it is necessary to enter the agricultural system and be domesticated and corrected. Taking and selecting and selecting from indigenous populations is helpful in correcting the plant. So necessarily, in order to achieve these goals in the domestication process, we must first consider the simplest way of reforming the selection of the population (Taiz and Zaiger, 2000). Due to the fact that hawthorn is one of the most important medicinal plants, this study is to study and select among native peoples of Khorasan Razavi province for quantitative traits. In this study, 10 populations of Husqvarna including Davarzan, Almagagh, Bashrooye, Sarband Kalat, Golmakan, Fariman, Kashmar, Rabat Sang, Ghale Zou and Bakhzar were used. To analyze the variance and analyze the data obtained using SPSS 19 and SAS software Became Optimum Duncan test was used to compare the means. Excel software was used to draw shapes and charts. Histogram and dentogram were used in this study. In the 6th generation of Flixweed cultivars, the highest 1000-seed weight was observed in the flowering population of 1.17 grams. The minimum weight of 1000 seeds was also obtained in the robotic population of 1.12 grams. There was a significant difference between the Golmakan treatments with the second largest population, namely, the population of Almagagh. The results of cluster analysis of functional traits (germination percentage, germination rate, seed germination index, mean germination time) are shown in the form of dentograms in the first and last generation. According to the results, in the first generation, the most similarity was observed in the low and poor levels of functional traits in the wildlife species, Rabat Stone and Fariman, which are above the graph. Also, in the first generation, the highest similarity was observed in terms of high values of functional traits in Golmakan, Sarband Kalat and Qala Zou populations, which are below the graph. According to the results obtained in the 6th generation, the most similarity was observed in the low and low levels of functional traits in the populations of Bashrooye, Davarzan and the rock interface, which are above the graph. Also in the 6th generation, the most similarities were observed in the germination traits in Golmakan, Sarband Kalat, Qala Zou populations, which are below the graph. This suggests that the populations mentioned include Golmakan, Sarband Kalat, Qala Zhu have a high potential for reforming processes and increasing functional traits, which is the most important part for plant breeding.
