abstract = "Cilj istraživanja bio je da se odredi uticaj različitog tipa citoplazme (cms-C, cms-S i fertilna), i
faktora spoljašnje sredine na dubinu zrna dvanaest inbred linija kukuruza. Ogled sa inbred
linijama postavljen je na dve lokacije (Selekciono polje i Školsko dobro) tokom 2017. i 2018.
godine. Ogledi su postavljeni po slučajnom blok sistemu u okviru svakog tipa citoplazme u tri
ponavljanja.
Statističko-biometrijska obrada podataka se zasnivala na srednjim vrednostima po ponavljanju i
obuhvatila je analizu varijanse. Na osnovu analize varijanse utvrđeno je da postoje veoma
značajne razlike između inbred linija na dubinu zrna u zavisnosti od tipa citoplazme, godine i
lokacije. Prosečan procenat dubine zrna inbred linija kretao se od 0.68cm do 0.89cm. Variranje
dubine zrna inbred linija u zavisnosti od tipa citoplazme bilo je veoma značajno. Najveća
prosečna vrednost za ovu osobinu zabeležena je kod sterilne citoplazme cms-C (0.78cm), a
najmanja kod fertilne citoplazme (0.76cm). Srednje vrednosti dubine zrna inbred linija veoma
značajno (P≤1%) su varirale u zavisnosti od godina ispitivanja i lokacija. Veću prosečnu dubinu
zrna imale su inbred linije u 2018. godini u odnosu na 2017. godinu. Na prvoj lokaciji ostvarena
je veća prosečna vrednost dubine zrna u odnosu na drugu lokaciju. Interakcija inbred linija x tip
citoplazme x lokacija je pokazala da je bilo statistički značajnih (Lsd0.05) razlika u prosečnim
vrednostima dubine zrna kod svih ispitivanih inbred linija. Interakcija tip citoplazme x godina x
lokacija bila je veoma značajna (Lsd0.01) za osobinu dubina zrna, što ukazuje da inbred linije
različitog tipa citoplazme različito reaguju u različitim godinama i lokacijama. Analiza
dobijenih rezultata ukazuje na značajan uticaj tipa citoplazme na dubinu zrna inbred linija
kukuruza.The aim of the present study was to determine effects of both, different types of cytoplasm (cms C, cms-S and fertile) and environmental factors on the kernel depth of 12 maize inbreds lines.
The trial with inbred lines was set up in two locations (Zemun Polje - Selection field and Zemun
Polje - Školsko dobro) in 2017 and 2018. The three-replicate trials were set up according to the
randomised block design within each type of cytoplasm.
Statistical-biometric data processing was based on means over replications and encompassed the
analysis of variance. Very significant differences in the kernel depth among inbred lines, in
dependence on the type of cytoplasm, year and the location, were established by the analysis of
variance. The average percent of the kernel depth significantly varied (P≤5%) in respect of the
observed cytoplasm type. The highest and the lowest values of this trait were established in
sterile cytoplasm cms-C (0.89cm), and fertile cytoplasm (0.68cm), respectively. The kernel depth
very significantly (P≤1%) varied in dependence on the year and location of investigation. The
greater proportion of the kernel depth was determined in maize inbreds in 2018 than in 2017. A
higher average value of the kernel depth was determined in the first location than in the second
location. The inbred lines × cytoplasm type × location interaction showed that there were
statistically significant (Lsd0.05) differences in average kernel depth values for all inbred lines
tested. The cytoplasmic type × years × location interaction was very significant pointing out that
inbred lines of different types of cytoplasm responded differently over years and locations. The
analysis of the results indicates a significant influence of a cytoplasmic type on the kernel depth
of maize inbred lines.
