Influence of hybrid combinations on the maize seed traits

In this paper the influence of hybrid on the particular traits of maize seed was examined. Four maize hybrids were tested on four locations. Analysed traits were: yield, ratio of seed fractions and germination by fractions. Yield differed among the hybrids. Hybrid ZP 427 achieved the highest yield per area unit (5,522.4 kg/ha), and ZP 434 had the lowest, with 2,357.8 kg/ha. The ratio of seed fractions differed significantly depending on the hybrid. Based on the results we can conclude that hybrid ZP 600 had the best ratio of fractions, with 76.2 % of small fraction. In all tested hybrids large fractions had higher germination efficiency. The highest average germination was observed in large fractions of hybrid ZP 666 (97.87 %), while the lowest germination was at small fractions of ZP 600 (92.38 %). On all three examined traits there was significant effect of both genotype and location, as well as their interaction.
