Hi Ravinder...

Just by removing one set of [] makes your version fully POSIX compliant:
Code:
#!/usr/local/bin/dash

echo 'C,rs18768
G,rs13785
GA,rs1065
G,rs1801279
T,rs9274407
A,rs730012' > /tmp/text

while IFS=, read field1 field2
do
    if [ ${#field1} -eq 1 ]
     then
        field1=${field1}${field1}
    fi
    echo "$field1,$field2"
 done < /tmp/text

Results, OSX 10.14.3, default bash terminal, calling dash:
