The ears are picked at an early green stage, and used for canning or fresh consumption. Approximately 40% of sugar com is frozen and the rest is canned after processing. In India, it is gaining importance, particularly in quality hotels in urban areas for the preparation of spedal soups, jams, cream pastries and other delicades. sweetcom differs from dent corn by one recessive gene, Su, on the 4th chromosome which prevents the conversion of some of the sugars into starch. (Kempton 1928; Linderstrom 1929; smith 1955). The variety Madhuri was the first sweetcom variety released in India by the Agricultural Research station (Maize) in Amberpet, Hyderabad in 1990. This variety has become popular in Andhra Pradesh and in many other states of India. It contains about 9% tota1 sugar on a dried-seed basis, while up to 33% on a milky- or fresh-grain basis, along with 16% fat and 15% protein. Improvement of sweetcom yields while retaining quality is one of the major challenges faced by the sweetcom breeders (Hunsperger and Davis 1987) ER -
