dc.description.abstractU ovom radu analizirano je sedam inbred linija kukuruza razlilčitog porekla i dužine vegetacionog perioda. Svaka linija je bila ispitivana u pet varijanti: originalna linija (N), CMS-C, RfC, CMS-S i RfS. Cilj rada je bio upoređivanje agronomskih karakteristika originalnih inbredovanih linija i njihovih CMS i Rf varijanti. Na osnovu poređenja između C i S-tipa linija cilj je bio da se utvrdi koji je od ta dva tipa sterilnosti pogodniji za semensku proizvodnju kukuruza.Nakon dve eksperimentalne godine utvrđeno je da su svih sedam inbred linija pokazale zadovoljavajući stepen sterilnosti. Ni kod jednog tipa (C i S) nije došlo do probijanja sterilnosti (late break of sterility). Sterilne linije su dale viši prinos od svojih analoga. C-tip sterilnosti se pokazao kao nešto bolji za semensku proizvodnju jer je prinos zrna bio veći u poređenju sa S-tipom. Takođe se može reći da je poređenjem ova dva tipa sterilnosti ustanovljeno da je C-tip bio bolji od S-tipa za veći broj ispitivanih agronomskih osobina.Na osnovu fitopatoloških analiza konstatovano je da je S-tip tolerantniji na gljivu Fusarium verticillioides, dok za linije C-tipa se može reći da su otpornije na napad gljive Aspergilus flavus.Parametri stabilnosti po Eberhartu i Rassellu govore da je na osnovu srednjih vrednosti kvadratnog odstupanja od regresije za prinos zrna, S-tip nešto stabilniji od C-tipa u različitim uslovima spoljnjašnje sredineUpotrebom izoelektričnog fokusiranja ustanovljeno je da je prevođenje skoro svih inbred linija urađeno dobro i do kraja. Razlike između originalnih i prevedenih linija su se javile samo kod sledećih linija ZPL2 RfC i ZPL5 RfC. Iz toga se može zaključiti da su razlike u agronomskim osobinama između originalnih i pervedenih linija nastale usled plejotropnog efekta CMS i/ili Rf gena, ili usled njihove interakcije sa spoljašnjom sredinom.sr
dc.description.abstractSeven maize inbred lines of different origin and different FAO maturity groups were analysed in the present study. Each inbred line was observed in five variants: original inbred (N), CMS-C, RfC, CMS-S and RfS. The objective of the study was to compare agronomic traits of original inbreds and their CMS and Rf variants. The C- and S-type inbreds were compared with the idea to evaluate which of these two types of sterility were more appropriate for seed production.The two-year experimental results show that all seven maize inbred lines had satisfactory level of sterility. None of the type (C and S) showed the late break of sterility. The grain yield was higher in sterile inbreds than in their counterparts. C-type sterility was a bit more appropriate for seed production because grain yield was higher in comparison with the S-type. Furthermore, it can be underlined that the comparison of these two types of sterility showed that the C-type was better than S-type for the majority of observed agronomic traits.According to phytopathological analyses, S-type inbreds are more tolerant to the fungus Fusarium verticillioides, while C-type inbreds are more resistant to the fungus Aspergilus flavus.Based on stability parameters after Eberhart and Russell, i.e. on the mean squared deviation from regression for grain yield, the S-type is somewhat more stable than the C-type under various environmental conditions.Performed isoelectric focusing showed that conversion of all inbreds lines had been done well and completely. The differences between original and conversed inbreds were detected only in inbreds ZPL2 RfC and ZPL5 RfC. Hence, it can be concluded that the differences in agronomic traits between original and conversed inbreds occurred due to pleiotropic effects of CMS and/or Rf gene, or due their interaction with the environment.en
