ASSESSMENT OF MOLECULAR DIVERSITY OF SOYBEAN [Glycine max (L.) Merrill]” VARIETIES USING SSR MARKERS FOR EFFECTIVE SELECTION AND IMPROVEMENT

Abstract

The present experiment was taken up to study molecular marker diversity analysis of Soybean varieties using sixteen different SSR primers for effective selection and improvement of crop plant. The assessment of SSR diversity of twenty soybean genotypes revealed that the Jaccard’s similarity coefficient estimates between pair of different varieties varied from 0.59 [between Kalitur and JS 335, Ankur and Bhatt] to 0.92 [between PK 472 and Ankur]. The average number of alleles per primer was 4.125, while percentage of all bands that showed polymorphism was 100%. The UPGMA ordered the population of twelve varieties into two main groups namely Group A and Group B and five clusters. Based on dendrogram PS 1347 and Ankur were found to be most distant.
