Grain quality of maize inbred lines originated from local populations

Abstract

Evaluation of seed quality was done from seeds of inbred lines originated from local maize populations of Eastern Serbia. Following parameters were investigated: 1000 seed weight, dry matter content, protein content and lysine content. In this study, 1000 seeds weight ranged from 311.03 to 365.04 g. In dry matter content were included soluble carbohydrates, starch, ash, and the remainder of proteins. It ranged from 10.14 to 10.96 %. The protein content is ranged from 9,31 to 10,84 %, but the crude protein content is not necessarily an indicator of quality. Important quality indicator is the amount of the essential amino acids and their digestibility. Several lines were obtained a lysine content up to 3 %, which is considered to be the high content of lysine in the 'normal' maize types. The results indicated that the local maize populations can be a significant source of beneficial genes to obtain better quality hybrids.
