AB  - Due to the low biological value of proteins of common maize, it was reinitiated breeding for high protein quality maize (HQPM) using three genetic systems, namely: opaque-2 gene, endosperm modifier genes and enhancer genes, which are increasing lysine and tryptophan content in opaque-2 background In order to alleviate effect of abiotic and biotic stress factors, the genotypes with tolerance to those factors were included. Genetic resources originating from North, Central and South America, then West, Central and Southern Africa and gene bank of Maize Research Institute 'Zemun Polje' were used. Combining breeding approaches in selection of genetic resources, field plot techniques and laboratory analysis, it was created large number of early QPM varieties, inbred lines and hybrids with modified endosperm and high yield potential under poor and good growing conditions. Created lines exhibited high combining ability in conventional and non-conventional hybrids. Yield trials showed that QPM hybrids are competing with commercial hybrids of common maize.

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.

Sadržaj triptofana u celom zrnu genotipova ukrštanja QPM i opaque2 linija je bio na nivou karakterističnom za QPM, sa nekoliko izuzetaka.

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  - 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.

abstract = "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., 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.",
