Abstract

The genus Allium comprises plants of signifi cant economic and medical importance, including onion,
garlic, and leek plants. The genetic diversity of garlic plants (Allium sativum) is vital for improving
agricultural practices, developing resilient crops, preserving genetic resources, and exploring the full
range of culinary and medicinal potential within this important plant species. In this research, we
investigated the results of genetic barcoding, focusing on the internal transcribed spacer (ITS) region;
four distinct barcoding regions, matK, rbcL, and trnH-psbA; and the trnL and Inter Simple Sequence
Repeats (ISSR) regions of Allium sativum L. (Amaryllidaceae), which were collected from three diverse
cultivation sites. Our findings revealed signifi cant interspecifi c diversity and intraspecifi c divergence
among the three cultivars examined. Interestingly, the results from different genetic markers were
consistent, with BDUT 1451 and 1452 consistently grouping together, while BDUT 1450 diverged. These
fi
ndings emphasize the effectiveness of the multi-marker approach for exploring intricate genetic
landscapes. Furthermore, they highlight the importance of genetic studies in understanding the diversity
of breeding and the potential utility of this economically and medicinally important nutraceutical crop.
