Characteristics of new maize inbred lines and their hybrids with high nutritional and feed qualities

Abstract

Breeding and selection of inbred lines ZPPL 146 and ZPPL 159 and hybrids developed from them (ZP 633, ZP 735 and ZP 737, primarily intended for feed) have been carried out for almost three decades. These inbred lines and hybrids have high nutritive values, they are rich in pigment properties, have efficient photosynthesis and other relevant parameters characteristic for standard hybrids. Observed maize hybrids are very important as carbohydrate rich nutrients. Feed produced from these hybrids is of high productivity and high quality. Due to their high productivity of total dry matter per area unit, these hybrids represent one of the most important forage products. Moreover, the study presents the importance of the chemical composition of maize hybrid grain in essential biogenic substances particularly pigments that have antioxidant properties.
