AB  - Grain spike index indicate wheat productivity and can be used as criterion in wheat selection in
the wheat breeding program. Aim of this investigation is study of variability of grain spike index
in wheat cultivars grown under different environmental condition. Ten genetically divergent
winter wheat cultivars were included in two year investigation in field experiment in randomized
block design in three replications. The seeds of varieties were sown at the distance of 0.10 m in
rows of 1.0 m length with the distance of 0.2 m. For analysis of grain spike index determined in
proportion of grain mass spike-1/mass of spike, 60 plants in full maturity stage (20 plants per
replication) were used. On the base of analysis of variance by using MSTAT C (5.0 version) and
computed F-test values, differences among cultivars according to value of grain mass spike-1,
mass of spike and also, spike harvest index were established. In the first year the highest spike
harvest index was 0.82 (Fortuna) and the lowest 0.76 in Ljubičevka, with average for all
varieties 0.79, while in the second year the highest spike index was 0.83 in Somborka, and the
lowest 0.77 in Ljubičevka, with average value 0.80. The different values of spike harvest index
indicate response of genotypes to environmental factors as well as interaction of
genotype/environment.

AB  - The stem height of wheat has impact on grain yield. Variability of height of wheat stem
depends from environment and genetic structure of varieties. The aim of this study was
estimation of impact of genetic components and environmental conditions on variability of
stem height in 10 genetically divergent wheat varieties. The experiment was set up as a
randomised block design in three replications. Obtained results indicated differences in
average values of stem height among tested wheat varieties in each year of experiment. In the
first year of study, the least stem height had Danica variety (44.87 cm) and the highest stem
height had wheat variety Ljubičevka (64.73 cm. In the second year stem height varied
between 64.37 cm in Danica variety and 87.97 cm in Šumadija variety. In average for all
varieties the height of stem was higher in the second year than in the first year of experiment.
Also, in average the value of height of stem was higher in second year than in the first year, in
all analysed wheat varieties. The highest height of stem, expressed Šumadija variety in
average (87.97 cm) in the second year. The least value of stem height (44.87 cm) in average
had Danica variety in the first year of experiment. Based on the results significant differences
between the wheat varieties according to stem height was established and impact of genetic
factors prevailing compare to impact of environmental factors.

AB  - The main goal of plant breeding is to improve quality traits, yield and resistance to abiotic and biotic stress factors. A thousand years ago, people selected the best plants, seeds or fruits to produce seed for new crops and food for human and animal nutrition. Modern plant breeding is based on genetic principles and contributes to  increases in yield  and quality components (contents of protein, amino acids, fat, sucrose, mineral elements etc.). Breeders in conventional breeding programs in the last six decades have made changes to plant phenotypes, significantly improved resistance to diseases, earliness, and frost and drought resistance, and improved scientific farming practices, baking and milling  technologies, and beverage production technology. Through bioinformatics and improved technology, breeders have developed ways to improve and accelerate the breeding process to combine desired traits in new genotypes as well to operate at the level of individual cells and their chromosomes. Nowadays, modern biotechnology is used to improve human nutrition, and develop genotypes with significantly higher yields and quality compared with genotypes created by conventional breeding. By genetic modification it is possible to add, modify or delete a trait without interfering between two complete genomes. However, genetically modified crops can be used after their assessment in terms of human health, food safety and the environment.

AB  - Advantages or disadvantages of intercropping system can estimate through expression of components of yield on the base of values of productive organs (spike, pod). The aim of this work was study of variation of spike index in cereals species and pods index in pea of spring intercropping. For investigation included spring species of small grains: wheat, triticale, oat and spring legume pea. The investigation was carried out in field condition in experiment with randomised block design of 5m2 plots, with 4 replications. Each species (cereals and pea) were sown sole and in intercrops wheat+pea, triticale+pea and oat+pea. At the maturity stage used 40 plants (10 plants/replication) for determining harvest index of spike in cereal species and index of pea pods on the base of analysis of spike mass and pod mass and seed mass spike-1 and seed mass pod-1 . Seed mass spike-1 of small grains species genotypes variate in ratio of 0.85 g (wheat+pea) and 1.59 g (oat intercrops) with average 1.19 g for all crops of cereals and variant of cultivation. The spike mass variate in range of 1.37 g (triticale intercrop) and 2.23 g (wheat intercrops) with average 1.72 g for all cereals and variant of cultivation. Harvest index of spike variate between 62.5% (triticale sole) and 89.2% (oat sole). The value of spike mass was the higher in wheat intercrops than in wheat sole, while for triticale and oat spike mass is lower in intercrops. In the same of analyzed small grain species, seed mass was the higher in sole crops than in mixture with pea. The spike index, only in intercrop triticale+pea (63.2%) was slightly higher than in single crop of triticale (62.5%). Pod mass and seed mass pod-1 of pea was the higher in pea intercrops than in pea sole. The highest pod mass was in intercrop pea+triticale (0.72 g) and the least in single crop of pea (0.45 g) with average 0.62 g for all crops. The highest seed mass pod-1 was the highest intercrop pea+triticale (0.56g) and the least in monocrop of pea (0.32 g) with average 0.46 g for all crops. Harvest index of pod variate in ratio 68.0% (pea single) and 77.% in pea/triticale intercrop. Pod index of pea in mixture with each small grains species genotypes was higher than in pea's monocrop. On the base of result we can conclude that intercropping cereals + pea, have positive effect on spike and pod characteristics which values were higher in majority of studied intercrops than in monocrops.
AB  - Prednosti i nedostaci združenih useva mogu se oceniti prema ispoljavanja komponenti prinosa na osnovu vrednosti produktivnih organa (klas, mahuna). Cilj ovog rad je izučavanje varijabilnosti žetvenog indeksa klasa pšenice, tritikalea, ovsa i žetvenog indeksa mahune kod graška gajenim u pojedinačnim i združenim usevima. U istraživanja je uključen po jedan genotip jarih formi pšenice, tritikalea, ovsa i graška. Eksperiment je izveden na oglednom polju Rimski šančevi u Institutu za ratarstvo i povrtarstvo Novi Sad. Genotipovi strnih žita i graška su sejani na parcelicama 5 m2 u 4 ponavljanja u monokulturi i u združenoj setvi pšenica + grašak, tritikale + grašak i ovas+grašak. U vreme fiziološke zrelosti vršena je žetva biljke koje su korišćene za analizu osobina klasa i metlice kod strnih žita i osobina mahune kod graška. Za analize je korišćeno 40 biljaka (10 biljaka po ponavljanju) za svaki genotip iz pojedinačnih i združenih useva. Analizirane su osobine: masa klasa, masa semena po klasu, masa mahune i masa semena po mahuni. Na osnovu vrednosti ovih osobina izračunat je žetveni indeks klasa kod pšenice, tritikalea i ovsa kao i žetveni indeks mahune kod graška. Masa klasa je varirala između 1.37 g kod tritikalea u združenom usevu sa graškom, do 2.23 g kod pšenice u združenom usevu sa graškom, a prosečna masa klasu za sve genotipove u obe varijante gajenja je iznosila 1.72 g. Masa semena po klasu je varirala od 0.85 g kod pšenice u združenom usevu (pšenica+grašak) i u do 1.52 g kod ovsa u združenom usevu sa graškom, a prosečna masa semena po klasu za sve genotipove u obe varijante gajenja je iznosila 1.19 g. Žetveni indeks klasa je bio najmanji 62.5% kod tritikalea u pojedinačnm usevu a najveći kod ovsa 86.5% takodje u monokulturi. Vrednosti mase klasa i mase semena po klasu su bile različite u zavisnosti od vrste strnih žita i načina setve i gajenja useva. Masa klasa kod pšenice u združenom usevu sa graškom je bila veća nego kod pšenice u pojedinačnom usevu. Kod tritikalea i ovsa masa klasa je bila veća u pojedinačnom usevu nego u njihovom združenom usevu sa graškom.

abstract = "Advantages or disadvantages of intercropping system can estimate through expression of components of yield on the base of values of productive organs (spike, pod). The aim of this work was study of variation of spike index in cereals species and pods index in pea of spring intercropping. For investigation included spring species of small grains: wheat, triticale, oat and spring legume pea. The investigation was carried out in field condition in experiment with randomised block design of 5m2 plots, with 4 replications. Each species (cereals and pea) were sown sole and in intercrops wheat+pea, triticale+pea and oat+pea. At the maturity stage used 40 plants (10 plants/replication) for determining harvest index of spike in cereal species and index of pea pods on the base of analysis of spike mass and pod mass and seed mass spike-1 and seed mass pod-1 . Seed mass spike-1 of small grains species genotypes variate in ratio of 0.85 g (wheat+pea) and 1.59 g (oat intercrops) with average 1.19 g for all crops of cereals and variant of cultivation. The spike mass variate in range of 1.37 g (triticale intercrop) and 2.23 g (wheat intercrops) with average 1.72 g for all cereals and variant of cultivation. Harvest index of spike variate between 62.5% (triticale sole) and 89.2% (oat sole). The value of spike mass was the higher in wheat intercrops than in wheat sole, while for triticale and oat spike mass is lower in intercrops. In the same of analyzed small grain species, seed mass was the higher in sole crops than in mixture with pea. The spike index, only in intercrop triticale+pea (63.2%) was slightly higher than in single crop of triticale (62.5%). Pod mass and seed mass pod-1 of pea was the higher in pea intercrops than in pea sole. The highest pod mass was in intercrop pea+triticale (0.72 g) and the least in single crop of pea (0.45 g) with average 0.62 g for all crops. The highest seed mass pod-1 was the highest intercrop pea+triticale (0.56g) and the least in monocrop of pea (0.32 g) with average 0.46 g for all crops. Harvest index of pod variate in ratio 68.0% (pea single) and 77.% in pea/triticale intercrop. Pod index of pea in mixture with each small grains species genotypes was higher than in pea's monocrop. On the base of result we can conclude that intercropping cereals + pea, have positive effect on spike and pod characteristics which values were higher in majority of studied intercrops than in monocrops., Prednosti i nedostaci združenih useva mogu se oceniti prema ispoljavanja komponenti prinosa na osnovu vrednosti produktivnih organa (klas, mahuna). Cilj ovog rad je izučavanje varijabilnosti žetvenog indeksa klasa pšenice, tritikalea, ovsa i žetvenog indeksa mahune kod graška gajenim u pojedinačnim i združenim usevima. U istraživanja je uključen po jedan genotip jarih formi pšenice, tritikalea, ovsa i graška. Eksperiment je izveden na oglednom polju Rimski šančevi u Institutu za ratarstvo i povrtarstvo Novi Sad. Genotipovi strnih žita i graška su sejani na parcelicama 5 m2 u 4 ponavljanja u monokulturi i u združenoj setvi pšenica + grašak, tritikale + grašak i ovas+grašak. U vreme fiziološke zrelosti vršena je žetva biljke koje su korišćene za analizu osobina klasa i metlice kod strnih žita i osobina mahune kod graška. Za analize je korišćeno 40 biljaka (10 biljaka po ponavljanju) za svaki genotip iz pojedinačnih i združenih useva. Analizirane su osobine: masa klasa, masa semena po klasu, masa mahune i masa semena po mahuni. Na osnovu vrednosti ovih osobina izračunat je žetveni indeks klasa kod pšenice, tritikalea i ovsa kao i žetveni indeks mahune kod graška. Masa klasa je varirala između 1.37 g kod tritikalea u združenom usevu sa graškom, do 2.23 g kod pšenice u združenom usevu sa graškom, a prosečna masa klasu za sve genotipove u obe varijante gajenja je iznosila 1.72 g. Masa semena po klasu je varirala od 0.85 g kod pšenice u združenom usevu (pšenica+grašak) i u do 1.52 g kod ovsa u združenom usevu sa graškom, a prosečna masa semena po klasu za sve genotipove u obe varijante gajenja je iznosila 1.19 g. Žetveni indeks klasa je bio najmanji 62.5% kod tritikalea u pojedinačnm usevu a najveći kod ovsa 86.5% takodje u monokulturi. Vrednosti mase klasa i mase semena po klasu su bile različite u zavisnosti od vrste strnih žita i načina setve i gajenja useva. Masa klasa kod pšenice u združenom usevu sa graškom je bila veća nego kod pšenice u pojedinačnom usevu. Kod tritikalea i ovsa masa klasa je bila veća u pojedinačnom usevu nego u njihovom združenom usevu sa graškom. Masa semena po klasu kod pšenice, tritikalea i ovsa bila je veća u pojedinačnom usevu nego u njihovom združenom usevu sa graškom. Žetveni indeks klasa u monokulturi: kod pšenice (71.9%) je bio veći nego u združenom usevu pšenica+grašak (70.8%), kod tritikalea (65.3%) je bio veći nego u združenom usevu (tritikale+grašak) i kod ovsa (89.2%) je bio veći nego u združenom usevu sa graškom (88.1%). Kod graška, masa semena po mahuni je varirala od 0.33 g u pojedinačnom usevu do 0.57 g u združenoj setvi sa tritikaleom, a prosečna masa semena po mahuni u oba sistema gajenja bila 0.46 g. Masa mahune je bila najmanja kod graška u pojedinačnom usevu 0.45g a najveća 0.72 g u združenom usevu sa tritikaleom, a prosečna vrednost mahune u svim varijantama gajenja je iznosila 0.59 g. Žetveni indeks mahune je varirao između 72.9% u pojedinačnom usevu graška i 79.4% u usevu združene setve graška i ovsa. Vrednosti za masu mahune, masu semena po mahuni i žetveni indeks mahune su bile veće u združenim usevima graška sa pšenicom, tritikaleom i ovsom ali nizi bile značajno različite. Dobijeni rezultata, ukazuju da združena setva graška i strnih žita ima pozitivan efekat na ispoljavanje većih vrednosti osobina klasa i osobina mahune.",
