The purpose of write this paper is to study the genetic variability between and within different Halosylon salicornicum populations in different regions of Saudi arabia Kingdom, using the determination of genetic fingerprint method by Inter Simple Sequence Repeat (ISSR). Because this plant highly vulnerable to depletion by humans in all places of existence, it is an economically valuable plant where raft is an important pastoral resource in central and northern Arabia. It also has multiple medical uses. It is a plant that can withstand abiotic stresses such as drought and high temperature, making it suitable for cultivation in marginal lands in arid areas. All of the above was a catalyst for plant characterization using a number of Haloxylon salicornicum samples, collected from different regions of Saudi Arabia to find out the genetic variation of species, genetic diversity in knowing the plant community is an essential step towards the design of programs for plant breeding as well as preserved from extinction. This was done using the Inter Simple Sequence Repeat (ISSR). The results showed there were significant differences and molecular differences between plant samples. The average polymorphism between the genetic inputs of the studied Haloxylon salicornicum samples was 53.7%, and this percentage of genetic variability is significant for progress in growth and plant regeneration in the face of unfair practices against it, in addition to adverse environmental conditions in most years. As evidenced by the percentage of matrix similarity. The ISSR results indicate that the genotype between five different regions genotypes ranged from 0.365 to 0.527, indicating that Haloxylon salicornicum is a local plant capable of surviving and adapting to the environmental conditions in Saudi Arabia through the positive change in the genetic makeup of this species.

撰写本文的目的是使用间作简单序列重复法（ISSR）确定遗传指纹方法，研究沙特阿拉伯王国不同地区不同盐藻的种群之间及其内部的遗传变异。由于这种植物极易在所有存在的地方被人类消耗，因此它是具有经济价值的植物，木筏是阿拉伯中部和北部的重要牧草资源。它还具有多种医疗用途。它是一种能够抵抗干旱和高温等非生物胁迫的植物，非常适合在干旱地区的边缘土地上种植。以上所有都是使用多种梭梭Salicornicum进行植物鉴定的催化剂从沙特阿拉伯不同地区收集的样本，以找出物种的遗传变异，了解植物群落的遗传多样性是设计植物育种计划和保护物种灭绝的重要步骤。使用内部简单序列重复（ISSR）完成此操作。结果显示植物样品之间存在显着差异和分子差异。被研究的梭梭水杨的遗传输入之间的平均多态性样品的比例为53.7％，而且在大多数情况下，面对不利于不公平做法的遗传变异百分率，对于生长和植物再生的进展也很重要。如矩阵相似性百分比所证明。ISSR结果表明，五个不同区域基因型之间的基因型范围为0.365至0.527，这表明Haloxylon salicornicum是一种本地植物，能够通过积极改变该物种的基因组成而存活并适应沙特阿拉伯的环境条件。
