Abstract

Since the nineteen sixties research on basic breeding stock has breen underway at the University of Agricultural Sciences, Debrecen. Efforts were made to broaden the genetic background, principally by means of mutation techniques. This research was later continued by the Agricultural Co. Ltd, Debrecen, and included analyses of the crude protein content in the grain yield of various parental lines and their hybrids, the amino acid composition of the proteins and the calculated essential amino acid index. The results of analyses on the amino acids present in maize grain proteins indicate that certain major amino acids accumulate in greater quantities in the mutant lines and in certain hybrids developed from these lines. The contents of some amino acids increased compared to the parental lines in certain hybrid combinations, i.e. a heterosis effect could be demonstrated. Naturally, hybrid combinations were also found where the quantities of certain amino acids decreased, i.e. no heterosis effect was observed. In some of the parental lines or hybrid combinations the essential amino acid index was as high as 65-78% of that of egg white. It can be concluded from the results that hybrid combinations with high protein and amino acid contents and a favourable essential amino acid index can be developed if the parental lines are wisely chosen.
