Hi Raja,

Please find sample code below for your reference,and modify it as per your requirement which helps you to accelerate with the above requirement.

Apex Class:
public String STEP1_INTERACTION {get {return 'Interaction';}}


    public String step {get; set;}


    public Interaction__c InteractionRequest {get; set;}

    private String retUrl;

    public InteractionController() {
        step = STEP1_INTERACTION;

        ID accountId = ApexPages.currentPage().getParameters().get('accountId');

            InteractionRequest = new Interaction__c(Account__c =accountId);

            if (accountId != null)
                retUrl = '/' + accountId;
    public List <SelectOption>
              generateMPOptions(List <Schema.PicklistEntry> ple) {
               List <SelectOption> options = new List <SelectOption> ();
            for( Schema.PicklistEntry f : ple) {
              options.add(new SelectOption(f.getValue(), f.getLabel()));
            } return options;

    public String[] MPItems { get {
          String[] selected = new List <String>();
          List <SelectOption> sos = this.MPOptions;
              for(SelectOption s : sos) {
                    if (this.InteractionRequest.Discussion_Points__c.contains(s.getValue()))
return selected;

public set {
  String selectedConcat = '';
  for(String s : value) {
    if (selectedConcat == '') selectedConcat += s;
  else selectedConcat += ';' + s;

        this.InteractionRequest.Discussion_Points__c = selectedConcat;
            upsert this.InteractionRequest;

public List <SelectOption> MPOptions {get {
  return this.generateMPOptions(Interaction__c.Discussion_Points__c.getDescribe().getPicklistValues());
} private set;}
Visual Force Page:
<apex:pageBlockSectionItem > 
      <apex:outputtext     value="InteractionRequest.Discussion_Points__c"/>
<apex:selectCheckboxes value="{!MPItems}" layout="pageDirection">
<apex:selectOptions value="{!MPOptions}"/>
