The aim of the present work was to make a comparative study on the morphological traits of the silage maize hybrids bred in Martonvá sár, including two leafy hybrids, with special regard to the proportion of different plant parts (stover-leaves-car) and the dry matter yield per plant, including the effect of the year. Most of the traits were influenced to the greatest extent by the genotype, but in many cases the year also had a significant effect. The genotypexyear interaction was significant for the above-car leaf number and the proportion of the car, which meant that the ranking of the genotypes differed in the two years. The car attachment height/plant height ratio was least influenced by the year. The greatest differences were observed in plant dry matter production. To sum up, it can be said that the silage maize hybrids studied in this experiment produced outstanding green and dry matter yields even compared with the standards, and had reliable performance even in unfavourable years. The proportion of the car in the whole plant dry matter was almost as high as that of grain hybrids in the same maturity group. Based on literary data, this ensures satisfactory nutritive values in the silage. The greater number of leaves above the car and the lower proportion of stover in the whole plant dry matter in leafy hybrids may further improve these values.
