Objective: Wheat (Triticum aestivum L.) is the first grain in the world in terms of its importance and amount of production. The aim of this research is to find the genetic diversity among the spring wheat genotypes.
Methods: In this study, the genetic diversity of 32 spring wheat genotypes cultivated in the Gorgan University of Agricultural Sciences and Natural Resources in the crop year of 1401-1400 was investigated by measuring 12 kernel and flour quality traits.
Results: The results of analysis of principal components illustrated that the first five components explained a total of 89.05 percent of the variation among traits. The cluster analysis divided the studied genotypes into four groups. Based on the obtained results, the cultivars in the first group, all of which were Iranian, had the highest values of grain gluten, flour gluten and flour protein. The second group, which included the genotypes of Iraq, had the highest values in terms of grain moisture and index, and the lowest values in terms of flour protein, falling number, and hectoliter.
Conclusion: The studied spring wheat cultivars showed high genetic diversity in terms of traits. Therefore, suitable parents can be selected based on the desired trait, for crossing between cultivars in future breeding programs.

Objective: Comparison of morphological and phytochemical characteristics of annual and perennial wild and cultivated Kakuti in Razavi, North and South Khorasan provinces.
Methods: In this study, Ziziohora tenuior and Ziziphora clinopodioides was studied in sex region in Razavi, North and South Khorasan province in 2021.Plant samples were collected from each region and was planted in pots. The experimental design used in this experiment was a nested design with four replications.Also, by referring to the places where plants were collected in the target areas, all the morphological and phytochemical traits were measured for wildplants.
Results: Based on the results the most percentage of essential oil in annual and perennial kakuti belonging to Qain (0.75%) and Qochan (2.29%) respectively. Also, the percentage of pulgone in the annual kakuti in Bardeskan was higher than other studied cities (77.58%). The highest alphapinene (0.42%) and sabinen (1.31%) percentage of annual kakuti was belonging to Bojnord while of perennial kakuti essence in Qochan (0.89%) and bijnord (1.23%) was more than other cities.
Conclusion: The amount of phenol, flavonoid and antioxidan activity in annual and perennial kakuti under natural conditions and in Sarayan was higher than other treatments. Annual and perennial kakuti belonging to Bojnord had higher wet and dry yields than other ecotypes, while kakuti belonging to Sarayan had superiority in phytochemical characteristics.
