Winform ComboBox- Default Value Cannot Be Set

I have a simple comboBox control on my Winform. I would like to set one of the items of comboBox, as the default item that will be shown on form load:

duration_ComboBox.SelectedItem = duration_ComboBox.Items.IndexOf("0 minutes");
        duration_ComboBox.Text = duration_ComboBox.SelectedText;

I do have the 0 minutes item in the comboBox, but on from load the field remains empty.
Any ideas?

using System.Windows.Forms;

namespace SOFAcrobatics
{
    public partial class ComboBoxTesting : Form
    {
        public ComboBoxTesting()
        {
            this.InitializeComponent();
        }

        private void ComboBoxTesting_Load(object sender, EventArgs e)
        {
            List<String> items = new List<String>()
            {
                "0 minutes",
                "1 minutes",
                "2 minutes"
            };

            foreach (String item in items)
            {
                this.comboBox1.Items.Add(item);
            }

            this.comboBox1.SelectedIndex = 0;
        }
    }
}

Instead of setting Combo.SelectedItem, set Combo.SelectedIndex.

duration_ComboBox.SelectedIndex = duration_ComboBox.Items.IndexOf("0 minutes");

Hope this helps.
