Abstract:
Sorghum bicolor is most important cereal crops around the world where the availability of water is less. Study of genetic variability among the sorghum accessions will enable accurate results in breeding programme and in mapping studies. By using SSR markers evenly distributed on sorghum genome revealed that, all the 23 accessions originated from Marathwada (Maharashtra) region were grouped into three main classes and it show correlation with the biological status and other characteristics features of accessions. The gene diversity measured in term of polymorphic information content (PIC) was ranged between 0.00 to 0.24 with the average PIC value was found to be 0.067 where 0.24 PIC value indicated presence of two allele per locus. Expected heterozygosity or Gene diversity computed according to Nei (1973) and varied from 0.00 to 0.28 with an average of 0.07. A total of 9 SSR marker alleles were detected, with an average of 1.5 alleles per marker. Numbers of alleles per marker ranged from 1(msbCIR329, Xtxp021 and Xtxp278) to 2(Xtxp321, msbCIR306 and Xisep0310). The fragment size of allele ranged from 109(msbCIR329) to 252(Xtxp321 and Xtxp278).
