| Abstract | Soybean (Glycine max (L.) Merr.) is a key crop that contributes significantly to the global economy. In this work, 100soybean varieties were obtained from Can Tho University and analysed for diversity using an ISSR marker and nine yieldcomponent characteristics. The findings of principal component analysis indicate that the first axis accounted for the majority ofvariance in the germplasm (51.4%), followed by the second axis (18.1%). Thereby the seed width (group I), node number (groupII), and 100 seed weight (group III) within the axis all have a significant effect on the population's phenotype. Eight agromorphological characteristics (seed length, seed breadth, seed thickness, plant height, number of nodes, pod number, seednumber, and 100 seed weight) varied significantly across the 100 soybean germplasms. Classification of the samples into twoclusters was performed using ISSR markers analysis. The first cluster included 95 germplasms. Five distinct varieties comprisedthe second cluster (V57, V83, V62, V63, V67). Following a model-based structural study, two populations were formed, withsome genotypes mixing considerably. The study's findings are instructive for future research targeted at boosting the yields of the100 soybean varieties in Vietnam. |
