abstract = "U proizvodnji hibridnog semena kukuruza najvažniji zadatak je
proizvodnja kvalitetnog semenskog materijala, kao visina i stabilnost
prinosa. Visina prinosa zavisi od genetiĉkog potencijala za prinos,
dok stabilnost prinosa zavisi od sposobnosti reagovanja hibrida na
uslove sredine. Stabilnost u postizanju oĉekivanog prinosa jedna je
od najpoželjnijih osobina da bi genotip bio preporuĉen kao hibrid za
široko gajenje. U ovim istraživanjima se polazi od pretpostavke da se
prouĉavani hibrid kukuruza, razliĉit procenat uĉešća fertilnih biljaka
razliĉito ponašaju na promene faktora spoljašnje sredine, ĉime
ispoljavaju i razliĉitu stabilnost prinosa. Na osnovu te pretpostavke,
oĉekuje se izdvajanje razliĉitih nivoa fertilnih biljaka ĉiji prinos
najmanje varira pod uticajem promena spoljašnje sredine. Cilj rada
bio je da se izvrši procena stabilnosti prinosa zrna po Eberhart-u i
Russell-u (1966). Parametri stabilnosti (koeficijent - bi i standardna
greška regresije - S2di) su pokazali koji odnos sterilne i fertilne
varijante hibrida je ostvario najveću stabilnost, odnosno koji su
najbolje reagovali na povoljne, tj. nepovoljne uslove spoljne sredine.
Kod najstabilnijeg hibrida utvrđeno je uĉešće od 25% fertilnih biljaka
(bi - 1,000), dok je kod hibrida sa 60% uĉešća fertilnosti bolje
reagovao na povoljne uslove gajenja (bi - 1,326), a genotip koji je
bolje reagovao na lošije uslove spoljne sredine imao je 10% uĉešća
fertilnih biljaka (bi - 0,791)., In the production of hybrid maize seed, the most important task is to
produce high-quality seed material and to provide high and stable
yields. Yield depends on genetic potential of yielding, while stability
depends on ability of hybrids to respond to environmental conditions.
Stability in achieving expected yield is one of the most favourable
traits for a genotype to be recommended as a hybrid for wide
cultivation. The starting point in these studies was that observed
maize hybrid and different percentage of share of fertile plants would
differently respond to changes in the environmental factors, whereby
yield stability would differ. Based on this assumption, the
distinguishable levels of fettilie plants whose yields vary the least
under envoronmental conditions were expected. The aim was to
estimate grain yield stability after Eberhart and Russell (1966). The
stability parameters (coefficient - bi and standard error of regression
- S2di) point out to which ratio of sterile to fertile variant of the hybrid
had the highest stability, i.e. which variants responded best to
favourable, i.e. unfavourable environmental conditions. The share of
fertile plants in the most stable hybrid was 25% (bi - 1.000) while a
hybrid with 60% fertility responded better to favourable growing
conditions (bi - 1.326). A genotype that responded better to
unfavourable environmental conditions had 10% of fertile plants (bi -
0.791).",
