在1920年代,LewisStadler开始对辐照植物的遗传组成进行永久性改进。从那以后,与育种突变相关的研究越来越多,努力扩大和提高作物产量和质量。Stadler的发现始于玉米和大麦的X射线,后来扩展到使用伽马射线,热,和作物中的快中子。辐射已被证明是增加物种遗传变异的有效和独特的方法,包括大米。关于物理诱变剂对东南亚水稻产量和谷物品质的影响,已经进行了许多系统的评论。然而,现有文献仍然缺乏关于所用辐射类型的信息,所用的水稻种植材料,物理诱变剂的剂量,以及变异特征的差异。因此,本文旨在回顾东南亚国家在水稻作物中使用物理诱变剂的现有文献。在PRISMA声明审查方法的指导下,通过对Scopus的系统评价,确定了28项主要研究,科学直接,翡翠洞察力,多学科数字出版,以及2016年至2020年之间发布的MDPI期刊数据库。结果表明,96%的物品使用种子作为种植材料,80%的文章集中在伽马射线作为物理诱变剂的来源。伽马射线的最佳剂量约为100至250Gy,以改善植物发育,非生物胁迫,生化特性,以及大米的营养和工业品质。
In the 1920s, Lewis Stadler initiated the introduction of permanent improvements to the genetic makeup of irradiated plants. Since then, studies related to breeding mutations have grown, as efforts have been made to expand and improve crop productivity and quality. Stadler\'s discovery began with x-rays on corn and barley and later extended to the use of gamma-rays, thermal, and fast neutrons in crops. Radiation has since been shown to be an effective and unique method for increasing the genetic variability of species, including rice. Numerous systematic reviews have been conducted on the impact of physical
mutagens on the production and grain quality of rice in Southeast Asia. However, the existing literature still lacks information on the type of radiation used, the rice planting materials used, the dosage of physical
mutagens, and the differences in mutated characteristics. Therefore, this article aims to
review existing literature on the use of physical
mutagens in rice crops in Southeast Asian countries. Guided by the PRISMA Statement
review method, 28 primary studies were identified through a systematic
review of the Scopus, Science Direct, Emerald Insight, Multidisciplinary Digital Publishing, and MDPI journal databases published between 2016 and 2020. The results show that 96% of the articles used seeds as planting materials, and 80% of the articles focused on gamma-rays as a source of physical mutagens. The optimal dosage of gamma-rays applied was around 100 to 250 Gy to improve plant development, abiotic stress, biochemical properties, and nutritional and industrial quality of rice.
