Abstract
Twelve inbred lines and their 24 crosses were analysed for variability in dry matter yield of the whole plant and the grained - ungrained part, as well as variability in content of water, ash, crude proteins, crude fats, crude fibres and NFE, respectively with the aim to breed maize with high yield and digestibility of the ungrained part. The results have shown high variability between hybrids in dry matter yield of the whole plant, the ungrained part and crude fibres. Similar variability is recorded for inbred lines, too. The results of chemical analyses of hybrids and inbred lines have shown that crude protein content and crude fat content had low variability. In contrast, NFE and specially crude fibres had high variability. Begarding yield of the ungrained part and chemical composition, four out of 12 studied inbred lines have been selected as promising for further breeding. Three out of 24 studied hybrids should be tested for total dry matter and crude fibres digestibility.
