摘要

为了满足不断增长的全球人口对粮食的需求,必须开发高产杂交、品种和优质粮食作物。这可以通过采用分子标记系统来完成。育种者可以使用分子标记直接选择基因型,因为它们不受环境的影响。如果要在未来几十年避免气候变化,就必须提高作物产量,以满足世界各地日益增长的人口的需求,以及应对新病毒的威胁。农业面临着不断增长的人口带来的不断增长的需求,以及气候变化导致的生产面积受限的危险,如缺水、土壤盐碱化或不可预测的收获天气。植物育种的最终目标是培育更好的作物。作物产量是可以提高的。生物基因组中DNA碱基序列在种群中不同个体之间不同的任何区域(位点)都被称为分子标记。近年来,DNA标记被创造出来,并被证明是谷物育种的有效工具。本文的总体目标是评价标记在作物改良计划中的作用、种类和用途。

Molecular Markers: Their Importance, Types, and Applications in Modern Agriculture
: To meet the expanding global population's need for food, high-yielding hybrids, varieties, and superior populations of food crops must be developed. This can be accomplished by employing a molecular marker system. Breeders can use molecular markers to choose genotypes directly because they are not affected by the environment. Crop yields must be increased to meet the needs of growing people around the world, as well as the threat of new viruses, if climate change is to be avoided in the next decades. Agriculture is confronted with rising demand from a growing population, as well as dangers of restricted production area as a result of climate change, such as water scarcity, soil salinity, or harvest weather that is unpredictable. Plant breeding's ultimate goal is to create better crops. Crop productivity is something that can be improved. Any region (locus) in an organism's genome where the DNA base sequence differs among different individuals in a population is referred to as a molecular marker. DNA markers have been created in recent years and have shown to be effective tools for cereal breeding. The overall goal of this review paper is to evaluate the role, kind, and utility of markers in in crop improvement program.
