AB  - The estimation of variability of five maize inbred lines and their diallel hybrids related to the grain yield, superior-parent heterosis and general and specific combining abilities after the method developed by Griffing, (1956a) (Method I, mathematical model I) was the aim of this study. According to obtained results it can be concluded that the variability of this trait is significantly affected by a genotype, year and a genotype x year interaction. Since the depression of the ear length occurs in inbreds in inbreeding, this trait was greater in hybrids than inbreds, as expected. The highest average heterosis for the grain yield was determined in the hybrids F-7R x NS-1445 (157,38% in 2005.) and F-7R x BL-47 (114.23% in 2006). The analysis of variance of combining abilities for the grain yield pointed out to highly significantly positive values of GCA and SCA for the observed trait in both years of investigation. Non-additive genes (dominance and epistasis) had the significant importance for grain yield heritability, indicating that the GCA to SCA ratio was bellow 1. The inbreds F-7R and NS-1445 were genotypes with the highest GCA effects, while hybrid combinations NS-1445 x BL-47, F-7RxW-37A, F-7RxNS-1445 were population with significant SCA effects in both years of investigation. They encompass both parents with high GCA effects or one parent with high GCA effects and other with low GCA effects. This is probably a result of additive gene effects (additive x additive) of the interaction between parents.
AB  - Cilj ovog istraživanja je bio da se za prinos zrna kukuruza procene: varijabilnost inbred linija i njihovih dialelnih hibrida, heterozis u odnosu na boljeg roditelja i opšte i posebne kombinacione sposobnosti. Na osnovu dobijenih rezultata dvogodišnjeg istraživanja može se zaključiti da na varijabilnost ove osobine značajno utiču genotip, godina i njihova interakcija. Kao posledica fenomena heterozisa i depresije usled inbridinga, hibridi su u odnosu na linije u obe godine imali značajno veće srednje vrijednosti za prinos. Ispitivani genotipovi su specifično reagovali na uslove proizvodnje za prinos. Najveći prosečan prinos zrna imao je hibrid F-7R x NS-1445 u 2005. i njegova recipročna verzija u 2006. godini. Ustanovljene su značajne vrednosti OKS i PKS kod prinosa zrna. Odnos između OKS i PKS, pokazuje da dominantno delovanje gena ima preovlađujuću ulogu u nasleđivanju prinosa zrna. Najbolju OKS za prinos zrna pokazala je linija NS- 1445. Najveću vrednost PKS za prinos zrna pokazao je hibrid NS-1445 x BL-47 u obe godine. To je dokaz da pojedine hibridne kombinacije koje uključuju jednog roditelja sa dobrim OKS i drugog roditelja sa lošim OKS, mogu imati izuzetno vredne performanse. Ovo je verovatno posledica delovanja aditivnog tipa (aditivni x aditivni) interakcije među roditeljima. Ustanovljeno je da recipročno ukrštanje utiče na efekat PKS za prinos zrna, jer osim nuklearnih gena i plazma geni imaju važnu ulogu u nasleđivanju prinosa kukuruza. Najveću razliku u vrijednosti PKS za prinos zrna između direktnog i recipročnog ukrštanja ispoljio je hibrid F-7R x BL-47 u obe godine proučavanja. Pri tome su značajno veći prinosi ostvareni korišćenjem linije F-7R na poziciji majke umjesto oca.

Babic (2010): Inbred lines of different cycles of selection as donors of favourable alleles for the improvement of F-1 maize hybrids.- Genetika, Vol 42, No. 2, 339 - 348. Eight BSSS and BSCB1 inbred lines of different cycles of selection were studied with the aim to evaluate which inbreds had the highest relative values of favourable alleles for the improvement of the grain yield trait in an elite single cross maize hybrid. Based on estimated parameters mu G, UBND, PTC and NI it was determined that the inbreds B73 (C-5) and B84 (C-7), originating form the synthetic population BSSS had highest number of favourable alleles for the improvement of the grain yield. Both these inbreds belong to the later cycles of recurrent selections and proved to be better donors of favourable alleles than inbreds belonging to the earlier cycles of selection. The rank correlations of used parameters were positive and highly significant, while the highest values of correlations for yield were determined between mu G and NI, that is PTC and NI. The highest grain yield was recorded in the hybrid ZPL2 x B73, which also had the highest value of heterosis (174.9%) in the trial for estimation of loci relative values.
