T HE present-day method of corn breeding has met with outstandi.ng success in its application to sweet corn improvement. Many canmng companies are now utilizing hybrids exclusively in the production of their commercial canning crop. The superiority of hybrids, in uniformity, productiveness, and in many cases resistance to destrnctive diseases, has resulted in this rapid change from open-pollinated varieties to hybrid strains. The improvement of quality in hybrids also ranks as a major problem. While many of the "quality" attributes in sweet corn are difficult to evaluate on a numerical basis, pericarp tenderness appears to lend itself to fairly accurate measurement. The need for tender pericarp hybrids is of special importance in meeting the demand for types suitable for whole ear as well as in whole kernel canning methods. Detailed histological studies have been reported by Haddad ~ showing the changes which occur in the pericarp tissue during the development of the endosperm in sweet corn. Doxtator~ has made a recent report of previous studies at the Minnesota Agricultural Experiment Station on the measurement of quality in sweet corn. The present paper will present studies conducted since 1934 pertaining to the inheritance of pericarp tenderness in sweet corn.
