“…In IGNJATOVIC-MICIC et al (2015), MR of 13 high oil accessions was higher, but HF was the same as in our research. The results for MR and HE also coincide with results presented for high oil accessions and Top-Cross blends in VANCETOVIC et al (2017). Considering KD, the values found for the accessions were in concurrence with values detected for maize hybrids in ARMSTRONG and TALLADA (2012).…”

Nutritional quality of maize is low because maize protein is poor in several essential amino acids. The purpose of this research was to analyze agronomic traits and kernel biochemical and physical properties of 16 gene bank accessions which comprise a mini-core collection for grain quality and to identify populations for improving protein quality. Standard ZP341 hybrid was superior for half of agronomic traits tested, especially grain yield, which was higher from 24% to six times. Ten accessions had protein content over 14 % and were further analyzed for amino acid composition and kernel characteristics. Additionally, genetic relationships between the accessions were determined by Simple Sequence Repeats (SSRs) analysis with 30 primers. All accessions showed elevated contents of most essential amino acids. Population L492 with 1.87 and 0.68 g 100g-1 dry weight had the highest contents of leucine and phenylalanine, respectively, but also higher contents of most other analyzed amino acids (p<0.05). Cluster analysis based on SSRs also distinguished L492 by separating it from all other accessions. Compared to ZP341, accessions were significantly inferior in grain weight and dimensions (p<0.05), but superior in most hardness parameters (p<0.05). Pearson correlations revealed lack of negative correlations between biochemical traits, indicating a possibility for concurrent improvement of several amino acids. The best way of improving protein quality of elite materials is through backcrossing and as populations were chosen according to their good general combining ability (with IoDent, Lancaster and BSSS), they could serve for improvement of elite materials of these genetic origins.

“…Studies on landraces and OPVs as dynamic populations, with distinct identity, high genetic divergence and adaptation to local agro-ecological conditions showed that variations in physical and biochemical characteristics of grain are notably greater compared to those found among modern maize hybrids (Žilić et al, 2012;Anđelković et al, 2016). This certainly makes them interesting not only from the aspect of breeding, but also for their use for special purposes (Vančetović et al, 2017). In addition, the knowledge of the chemical variability of OP varieties contributes to the rescue of that germplasm and could be of economic interest, especially to the pharmaceutical, cosmetic and food industries.…”

The contemporary trends in maize breeding are directed at identification of genotypes with improved grain quality for human consumption, industrial processing, and their incorporation into breeding programmes. In this study, three maize hybrids and three open-pollinated varieties (OPVs), differing in grain colour and type, were used to examine the differences in the total carotenoid content, the phenolic compounds profile and total antioxidant capacity (TAC). In addition, physical parameters, basic chemical composition, as well as the content of protein fractions in grain, were analysed. The multivariate approach through Principal Component Analysis (PCA) application contributed to better understanding of the complexity of the interdependence for maize grain quality parameters tested. From the aspect of different end use, better technological quality desirable for dry milling and snack food processing found in OPVs Osmak and Bosanac, as well as high content of bioactive compounds (i.e. TAC) exhibited by OPV Rumenka, make these genotypes superior compared to hybrids' varieties evaluated.
