The goal of this study was to evaluate the diversity and the genetic relationships among ten the varieties of sorghum (Sorghum bicolor) using SSR markers. A field experiment was conducted at a greenhouse in Texas A&M University-Soil and Crop Science. Simple sequence repeat (SSR) markers reveals a high polymorphism ratio among sorghum cultivars, where polymorphism values ranged from (90%), (25.32%). The highest number of polymorphic bands (15) was given with primer (4), while the lowest band (6) gave with primer (26). The size of sequence primer ranged between (370) Pb with primer (21) and (370) Pb with primer (38). The genetic distance values ranged between (0.25) and (0.43), where the lowest was between sorghum cultivars (G7) and (G6), while the highest genetic distance was between (G10). In this study SSR markers were found to be powerful tools for identifying genetic diversity in sorghum populations. Markers are given high polymorphic values among of sorghum genotypes under study. Cluster analysis grouped the ten sorghum cultivars into nine groups based on genetic and morphological traits. We conclude that the results of SSR-PCR are extremely helpful in identify the genetic distance among sorghum genotypes. This leads to selection sorghum genotypes, and SSR may be used for producing commercial hybrids among them. [ABSTRACT FROM AUTHOR] |
