SUMMARY

 

Soko is an carly maturing maize hybrid, from the FAO 100 group, with yield potential of 11,7 t/ha of dry grain under favorable agriclimatic conditions. During the three year testing period (1997-1999) within the experimental network of the Yugoslav Federal Committee for recognition of varieties, it had average grain yield of 6.7 t/ha, which was 44% above the yield of the ZP 125 standard.

Slavuj is an early maturing maize hybrid, from the FAO 200 group, with yield potential of 12.2 t/ha of grain. During the three year testing period (1997-1999) within the experimental network of the Yugoslav Federal Committee for recognition of varieties, it had average grain yield of 9,0 t/ha, wich was 37 % above the yield of the NS 201 standard.

Dukat-4 a maize hybrid, from the FAO 400 group, with yield potential of 14.2 t/ha of grain. During the three year testing period (1998-2000) within the experimental network of the Yugoslav federal Committee for recognition of varieties, it realized an average grain yield of 9.8 t/ha, which was 7% above the yield of the NS 420 standard.

All three maize hybrids (Soko, Slavuj and Dukat-4) are exceptionally stable and resistant to causative agents of significant diseases H. turcicum, U. maydis and Fusarium spp, as well as to Ostrinia nubilalis.
