AB  - Maize has poor nutritional value due to deficiency of two essential amino acids - tryptophan and lysine. Although recessive opaque2 (o2) mutation significantly increases their content in the endosperm, incorporation of opaque2 into high yielding cultivars was not commercially successful, because of its numerous agronomic and processing problems due to soft endosperm. Quality protein maize - QPM has lately been introduced as opaque2 maize with improved endosperm hardness and improved agronomic traits, but mostly within tropical and subtropical germplasm. The ongoing breeding project at MRI includes improvement of MRI opaque2 lines and conversion of standard lines to QPM germplasm. The main selection steps in QPM breeding involve assessing kernel modifications and tryptophan level in each generation. Herein, we present the results of the analysis for these traits on F3 and BC1F1 generations of QPM x opaque2, opaque2 x QPM and standard lines x QPM crosses. The results showed that the majority the genotypes had kernel types 2 and 3 (good modifications). The whole grain tryptophan content in F3 and BC1F1 genotypes of crosses between QPM and opaque2 germplasm was at the quality protein level, with a few exceptions. All BC1F1 genotypes of standard lines x QPM had tryptophan content in the range of normal maize, while majority of F3 genotypes had tryptophan content at level of QPM. The progeny (with increased tryptophan levels) of QPM and opaque2 crosses had significantly higher tryptophan content compared to the progeny of crosses between standard and QPM lines - 0.098 to 0.114 and 0.080, respectively. All genotypes that had poorly modified kernels and/or low tryptophan content will be discarded from further breeding.
AB  - Iako recesivna opaque2 (o2) mutacija značajno povećava sadržaj lizina i triptofana u zrnu kukuruza, inkorporacija opaque2 u visoko prinosne genotipove nije uspela, zbog brojnih problema koji su se javili kao posledica mekog endosperma. Kukuruz visokog kvaliteta proteina (QPM) je opaque2 kukuruz sa poboljšanom tvrdoćom zrna i dobrim agronomskim performansama, stvoren prvenstveno od tropske i subtropske germplazme. U Institutu za kukuruz je u toku projekat koji za cilj ima poboljšanje sopstvenih opaque2 linija i prevođenje standardnih linija u QPM kukuruz. U ovom radu predstavljamo rezultate analiza modifikacije zrna i sadržaja triptofana u F3 i BC1F1 generacijama ukrštanja QPM x opaque2, opaque2 x QPM i standardne linije x QPM. Većina genotipova je imala zrno tipa 2 i tipa3 (dobre modifikacije). Sadržaj triptofana u celom zrnu genotipova ukrštanja QPM i opaque2 linija je bio na nivou karakterističnom za QPM, sa nekoliko izuzetaka. Sadržaj triptofana u potomstvu ukrštanja standardne linije x QPM je bio povećan kod većine F3 genotipova. Potomstvo (sa povećanim sadržajem triptofana) ukrštanja QPM i opaque2 linija je imalo znatno veći sadržaj ove aminokiseline u odnosu na potostvo ukrštanja standardne linije x QPM - - od 0.098 do 0.114 prema 0.080. Genotipovi sa lošim modifikacija zrna i/ili niskim sadržajem triptofana ce biti eleminisani iz daljeg procesa selekcije.

AB  - In this work, proteins and tryptophan content were analyzed in kernels of semi-flint, semi-dent, dent and specialty ZP maize hybrids. Protein content, as well as protein fraction, differed significantly among the analyzed maize genotypes. Globulin was the lowest fraction in kernels of all maize hybrids (6.69-11.03% of total protein). The content of albumin was the highest in sweet hybrids ZP 441su and ZP 461su i.e. 20.27% and 19.76% of total protein, respectively. α-Zein and G-3 glutelin were dominant protein fractions in all maize genotypes. The highest content of α-zein and G-3 glutelin was in the kernels of popping maize hybrid ZP 611k, i.e. 29.25 and 25.71% of total protein, respectively. All hybrids could be classified according to the tryptophan content in three groups - over 0.08% (sweet and waxy hybrids), from 0.06 to 0.07% (three standard dent hybrids, one semi-flint and two semident hybrid) and from 0.05 to 0.06% (two semi-flint, one semi-dent hybrids and popping).

AB  - The process of micronisation, a short time high temperature process that utilizes electromagnetic radiation in the infrared region to rapidly heat materials, is often used to improve storage stability of whole grain flour. In this work the consequences of such temperature treatment on the quality and solubility of proteins, viscosity, content of total phenolics, tocopherols, beta-carotene, as well as the antioxidant properties of maize (Zen mays L.) flour are presented. For these studies three maize hybrids were used: the semi-flint hybrid ZP 633 with pronounced yellow kernels, ZP Rumenka with dark red pericarp and yellow endosperm, and ZP 551b hybrid which is characterized by white kernels. The process of micronisation did not change the content of crude protein, the amount of albumin, globulin and zein were decreased, while glutelin remained the same or increased after micronisation. As a consequence of thermal effect on maize protein, tryptophan content was significantly decreased. Micronisation had a significant effect on the pasting properties of the selected maize flour. Viscosity of all micronised flour samples increased constantly, but without reaching a peak during heating of the slurry to 95 degrees C. At 95 degrees C it was slightly higher, but final viscosity at 50 degrees C was significantly lower. The micronisation treatment decreased the content of bioactive compounds (tocopherols, beta-carotene) naturally present in the raw grains. The whole grain flour from micronised grain, with modified nutritional and technological characteristics, represents a good raw material for production of gluten-free products.

AB  - Nutritional value of maize is poor due to deficiency of two essential amino acids - tryptophan and lysine. It was shown than opaque2 (o2) mutations can nearly double the lysine and tryptophan content of the endosperm compared with the normal type. Maize Research Institute Gene bank maintains a collection of opaque2 inbred lines developed in the seventies, primarily based on kernel hardness and analytical methods. In order to describe these lines in more detail they were analyzed for tryptophan content and subjected to SSR analysis with opaque2 markers, a marker for endosperm hardness modifier gene and the most significant amino acid modifier markers. Also, a pathogenicity test for inbred lines tolerance to Fusarium spp., which is one of the most important maize pathogens in our region and a causer of maize stalk, root and ear rot, was performed. Differences in tryptophan content between normal and opaque2 lines were significant. All primers used for distinguishing alleles between normal and opaqu2 inbred lines gave positive results. Each genotype gave a specific allelic pattern with amino acid modifier gene primers, without any obvious correspondence to the tryptophan content. Phythopathogenicity test showed on average higher susceptibility to Fusarium graminearum of opaque2 genotypes. These results gave an insight into the applicability of the methods in describing opaque2 lines to be converted into quality protein maize QPM - genotype in which opaque2 has been incorporated along with associated modifiers.
AB  - Kukuruz ima nisku hranjivu vrednost zbog nedostatka dve esencijalne amino kiseline - triptofana i lizina. Utvrđeno je da opaque2 (o2) mutacija može skoro udvostručiti sadržaj lizina i triptofana u endospermu kukuruza. Banka gena instituta za kukuruz 'Zemun Polje' poseduje kolekciju opaque2 inbred linija razvijenih tokom sedamdesetih godina, prvenstveno na osnovu tvrdoće zrna. Sa ciljem detaljnijeg opisa ovih linija urađena je analiza sadržaja triptofana i SSR analiza sa opaque2 markerima, markerom za gen modifikator tvrdoće endosperma i najsignifikantnijim markerima za gene modifikatore amino kiselina. Takođe je urađen test fitopatogenosti radi utvrđivanja osetljivosti opaque2 genotipova na Fusarium gramaenarum, jednog od najvažnijih prouzrokovača truleži stabla, korena i klipa kukuruza u našem regionu. Utvrđene su značajne razlike u sadržaju triptofana između normalnih i opaque2 linija kukuruza. Svi SSR prajmeri korišćeni za razlikovanje normalnih i opaque2 linija su dali pozitivne rezultate. Svaki od analiziranih genotipova je dao specifičnu alelnu sliku sa markerima za gene modifikatore amino kiselina, bez očigledne saglasnosti sa sadržajem triptofana. Test fitopatogenosti je, u proseku, pokazao veću osetljivost opaque2 linija na Fusarium graminearum. Ovi rezultati su dali uvid u primenjivost navedenih metoda za opisivanje opaque2 linija radi njihovog konvertovanja u kukuruz visokog kvaliteta proteina (QPM) - genotipa u koji se opaque2 inkorporira zajedno sa odgovarajućim genima modifikatorima.

These results gave an insight into the applicability of the methods in describing opaque2 lines to be converted into quality protein maize QPM - genotype in which opaque2 has been incorporated along with associated modifiers., Kukuruz ima nisku hranjivu vrednost zbog nedostatka dve esencijalne amino kiseline - triptofana i lizina. Utvrđeno je da opaque2 (o2) mutacija može skoro udvostručiti sadržaj lizina i triptofana u endospermu kukuruza. Banka gena instituta za kukuruz 'Zemun Polje' poseduje kolekciju opaque2 inbred linija razvijenih tokom sedamdesetih godina, prvenstveno na osnovu tvrdoće zrna. Sa ciljem detaljnijeg opisa ovih linija urađena je analiza sadržaja triptofana i SSR analiza sa opaque2 markerima, markerom za gen modifikator tvrdoće endosperma i najsignifikantnijim markerima za gene modifikatore amino kiselina. Takođe je urađen test fitopatogenosti radi utvrđivanja osetljivosti opaque2 genotipova na Fusarium gramaenarum, jednog od najvažnijih prouzrokovača truleži stabla, korena i klipa kukuruza u našem regionu. Utvrđene su značajne razlike u sadržaju triptofana između normalnih i opaque2 linija kukuruza. Svi SSR prajmeri korišćeni za razlikovanje normalnih i opaque2 linija su dali pozitivne rezultate. Svaki od analiziranih genotipova je dao specifičnu alelnu sliku sa markerima za gene modifikatore amino kiselina, bez očigledne saglasnosti sa sadržajem triptofana. Test fitopatogenosti je, u proseku, pokazao veću osetljivost opaque2 linija na Fusarium graminearum. Ovi rezultati su dali uvid u primenjivost navedenih metoda za opisivanje opaque2 linija radi njihovog konvertovanja u kukuruz visokog kvaliteta proteina (QPM) - genotipa u koji se opaque2 inkorporira zajedno sa odgovarajućim genima modifikatorima.",

AB  - Quality protein maize (QPM) contains the opaque-2 gene along with numerous modifiers for kernel hardness. Therefore, QPM is maize with high nutritive value of endosperm protein, with substantially higher content of two essential amino acids - lysine and tryptophan, and with good agronomical performances. Although QPM was developed primarily for utilization in the regions where, because of poverty, maize is the main staple food, it has many advantages for production and consumption in other parts of the world, too. QPM can be used for production of conventional and new animal feed, as well as for human nurture. As the rate of animal weight gain is doubled with QPM and portion viability is better, a part of normal maize production could be available for other purposes, such as, for example, ethanol production. Thus, breeding QPM is set as a challenge to produce high quality protein maize with high yield and other important agronomical traits, especially with today's food and feed demands and significance of energy crisis.
AB  - Kukuruz visokog kvaliteta proteina (QPM - Quality Protein Maize) sadrži opaque-2 gen, kao i mnogobrojne modifikatore za tvrdoću zrna. QPM se može definisati kao kukuruz sa visokom nutritivnom vrednošću proteina endosperma, odnosno značajno većim sadržajem dve esencijalne aminokiseline - lizinom i triptofanom, i istovremeno dobrim agronomskim perfomansama. Mada je QPM stvoren prvenstveno za korišćenje u regionima u kojima je, zbog siromaštva, kukuruz glavna hrana, postoje mnoge prednosti za proizvodnju i korišćenje ovog kukuruza i u ostalim regionima sveta. QPM se može koristiti za proizvodnju konvencionalne i nove hrane za životinje, kao i za ishranu ljudi. Zbog dvostruko bržeg prirasta telesne težine životinja i boljeg iskorišćavanja pripremljenog obroka QPM kukuruza, deo proizvedenog standardnog kukuruza bi se mogao preusmeriti za druge potrebe, kao na primer za proizvodnju etanola. Selekcija kukuruza za poboljšanje kvaliteta proteina, zajedno sa visokim prinosom i dobrim perfomansama drugih značjnih agronomskih svojstava, predstavlja izazov za selekcionere, pogotovo imajući u vidu današnje potrebe za hranom, kao i značaj energetske krize.
