Dear Punam Bhattcharjee, Can you be specific to your requirements? For descriptive statistical analysis Excel data analysis toolpack is enough which is inbuilt with MS excel.
I know R, PBtool, STAR, QTL ICIMapping, STRUCTURE, TASSEL, Excel, GenAlEx and recently MVApp, which is web-based. I have used all of these in my plant breeding and genetic experiments, and they are open access.
