ZP 5557- Novi hibrid kukuruza

Hibridi srednje grupe zrenja FAO 500 imaju sve veći značaj u proizvodnji kukuruza u Srbiji. Imajući u vidu da je u poslednjih nekoliko godina prisutan trend gajenja hibrida koji imaju niži sadržaj vlage u momentu žetve, hibridi grupe zrenja FAO 500 predstavljaju odličnu kombinaciju visokog prinosa i nižeg sadržaja vlage u zrnu. Mogu se ubirati i u klipu i u zrnu, što ih čini veoma dobrom alternativom za hibride kasnih grupa zrenja koji se odlikuju visokim potencijalom za prinos ali i visokim sadržajem vlage u žetvi. Hibrid ZP 5557 registrovan je 2023. godine. U ogledima Sortne komisije je ispitivan u periodu 2021-2022. godine. Karakteristično je da su obe godine bile nepovoljne za gajenje kukuruza, što se naročito odnosi na 2022. godinu. Hibrid ZP 5557 je u obe godine ispitivanja ostvario viši prosečan prinos u odnosu na prosek standardnih hibrida, uz niži sadržaj vlage i manji procenat poleglih i slomljenih biljaka. U dvogodišnjem proseku ostvario je prinos od 104,4% u odnosu na prosek standardnih hibrida. Na osnovu rezultata postignutih u ogledima sortne komisije, hibrid ZP 5557 biće uključen u postkomisijske oglede Instituta za kukuruz i u slučaju da ponovi dobar rezultat biće započeta komercijalizacija ovog hibrida.
Hybrids of medium maturity group FAO 500 become more important in maize production in Serbia. Taking into account that in the last few years there has been a trend of growing hybrids with lower harvest moisture, the hybrids of the FAO 500 maturity group represent an excellent combination of high yield and lower grain moisture content in harvest. They can be harvested both in ear and grain, which makes them a very good alternative for hybrids of late maturity groups that are characterized by high yield potential but also high moisture content at harvest. Hybrid ZP 5557 was registered in 2023. It was tested in the trials of the State Variety Commission in the period 2021-2022 years. It is characteristic that both years were unfavorable for growing maize, which especially applies to the year 2022. Hybrid ZP 5557 achieved a higher average yield in both years of testing compared to the average of check hybrids, with lower moisture content and a lower percentage of broken and lodged plants. In the two-year average, it achieved a yield of 104.4% compared to the average of check hybrids. Based on the results achieved in the tests of the variety commission, hybrid ZP 5557 will be included in the post-official trials of the Maize Research Institute and in case it obtain good result, the commercialization of this hybrid will be started.
