Germination of maize hybrids seed stored after harvest

In this investigation used three maize hybrids that are belongs to different group of ripening: FAO 3, FAO 4 and FAO 6. The seed of those hybrids used for investigation of genotypic divergences for seed germination, energy of germination, content of abnormal emergence of seeds, content of dead seeds. Hybrid seed for analysis produced on the experimental field of the Institute of Maize in Zemun Polje, Belgrade. The viability of the maize hybrids seeds were determined in experimental analysis carried out in laboratory for quality of seed in the Maize Research Institute Zemun Polje, Belgrade. According to standard method on filter paper were estimated the values of seed germination. The three experiment of seed germination carried out: 2 months after harvest, 9 months after harvest and 18 months after harvest. In average for each test the highest percentage of seed germination were found for hybrid ZP FAO3: 92.75% for seed after 2 months of harvest, 92.00% for seed 9 monhts after harvest and 91.50% for seeds after 18 months of harvest. This hybrid had the lowest percentage of ungerminated seeds (2.75%) and the least content of dead seed (~5.00%). The lowest value of seed germination (86.33%) and the highest values of ungerminated seed (~3.00%) as well the highest content of dead seed (10.33%) had hybrid belongs FAO 4 group. The obtained results indicate differences of germination in analyzed maize genotypes
