The present research was carried out with the aim of estimating some genetic parameters of Amygdalus scoparia variety using the REML method. For this purpose, 20 plants were randomly selected from among the plants in two populations in Kerman province, with a distance of at least 100 meters, and the seeds were collected separately. After applying the cold treatment, the seeds were transformed into seedlings and planted in pots in the educational and research greenhouse of Yazd University, they were cared for and irrigated. Measurement and recording of some traits of seedlings were done in the first year for the genetic evaluation of genotypes. The studied traits included height, neck diameter, number of sub-branches, and number of leaves, leaf length, and maximum leaf width and leaf shape. The results of present study showed that the length and width of the leaf blade, followed by the diameter of the collar and the height of the seedling showed the highest degree of heritability among the studied traits, and the highest genetic correlation was also between the traits of the number of leaves and the diameter of the collar, as well as between the traits of the width of the collar and seedling height and after that between two traits collar diameter and seedling height were observed. Given the high heritability observed for leaf length and width, followed by collar diameter and seedling height, this variety holds significant potential for use in breeding programs aimed at enhancing both the quality and quantity of this valuable species. |
