abstract = "In the process of hybrid maize breeding, the greatest attention is directed towards increasing the level and stability of the yield, while grain quality is of secondary importance. The very
principles of hybrid breeding, as well as the economic aspects and competition between different breeding companies, have led to an enormous narrowing of the genetic basis of commercial
maize hybrids. Concurrently, there is usually a small number of often related hybrids of similar
technological and nutritional quality present on the market. Six best-selling ZP maize hybrids
in the previous ten years were chosen as the subject of this study. In the period from 2009-2018,
both the yield components and parameters of technological and nutritional quality of the grain
were studied. It was found that the examined parameters varied a lot in different years of production and that some parameters were more influenced by genotype (number of kernel rows per ear,
portion of pericarp, and crude fiber content) while others were more influenced by the environment (kernel weight per ear, total protein, starch, and oil content, respectively). The amount and
the distribution of precipitation during the vegetative period affected not only the yield components i.e. grain yield but also the technological qualitz parametres and nutritional properties of
the grain. Based on the observed parental components, it is evident that they are related hybrids
that, despite the high genotype by environment interactions, consequently have similar parameters of technological quality and nutritional composition. The imperative is to develop special
breeding programs aiming to create both the starting material and parental components to provide hybrids of improved technological quality and nutritional properties on the market. In that
way, the needs of the processing industry for raw materials of certain characteristics can be met., U procesu hibridnog oplemenjivanja kukuruza, najviše pažnje se posvećuje povećanju nivoa
i stabilnosti prinosa, dok je kvalitet zrna od sekundarnog značaja. Sami principi hibridnog oplemenjivanja, kao i ekonomski aspekti i konkurencija između različitih oplemenjivačkih kuća,
doveli su do enormnog suženja genetičke osnove komercijalnih hibrida kukuruza. Na tržištu je
istovremeno najčešće prisutan mali broj, često srodnih hibrida sličnog tehnološkog i nutritivnog
kvaliteta. Za ovo istraživanje je odabrano šest ZP hibrida kukuruza najprodavanijih u prethodnih
deset godina. U periodu od 2009-2018. godine, praćene su, kako komponente prinosa, tako i
parametri tehnološkog i nutritivnog kvaliteta zrna. Utvrđeno je da su ispitivani parametri veoma
varirali u različitim godinama gajenja, kao i da su neki parametri bili pod većim uticajem genotipa (broj redova zrna, udeo perikarpa i sirove celuloze), a neki pod većim uticajem spoljašnje sredine (masa zrna po klipu, udeo ukupnih proteina, skroba i ulja, respektivno). Količina i raspored
padavina u toku vegetativnog perioda su uticali ne samo na komponente prinosa, odnosno na
prinos zrna, već i na parametre tehnološkog kvaliteta i nutritivna svojstva. Na osnovu posmatranih roditeljskih komponenata, evidentno je da se radi o srodnim hibridima koji, bez obzira na
visoke interakcije između genotipa i spoljašnje sredine, posledično imaju slične parametre tehnološkog kvaliteta kao i nutritivni sastav. Neophodno je razvijati posebne oplemenjivačke programe
koji imaju za cilj stvaranje kako početnog materijala, tako i roditeljskih komponenata, kako bi
se na tržištu obezbedili hibridi poboljšanog tehnološkog kvaliteta i nutritivnih svojstava i na taj
način zadovoljile potrebe prerađivačke industrije za sirovinama određenih karakteristika.",
