Solarization is a good idea, but you don't have to have a hybrid to have
disease resistance.  Those heirloom varieties would not be around if they
were susceptible to diseases.  Hybridizers pay universities (faculty
members, at least)to test for disease resistance.  Then they can claim
disease resistance.  That's really the only difference.  Margaret
