Hybrid progeny of F1 and F2 generations were produced in diallel crosses (without reciprocals) of five genetically divergent wheat cultivars (Zitnica, Jugoslavija, Zelengora, NS Rana 2 and Nizija). The variability, mode of inheritance, gene effect, combining ability of parent cultivars and F1 and F2 hybrids for NHI were studied. The different mode...

About 60% of wheat fields in Central Serbia have a soil pH below 5.5. Therefore, increasing and maintaining crop yields require periodic use of soil amendment practices (liming, phosphorus treatment and humification), along with fertilization. This study was conducted over a period of five years (2007-2011) on a pseudogley soil to evaluate the effe...

In this paper the inheritance of grain number per spike in hexaploid (6x) winter triticale was investigated. Studies were performed on primary spikes of parents, F1 and F2 progenies of a 5 x 5 complete diallel crossing with reciprocals. The results highlighted the prevalence of dominance and over-dominance in the expression of this trait at majorit...

Grain protein content is one of indicators of small grains quality. It is important trait, but negatively correlated with grain yield what represents obstacle in small grains breeding on quality and yield, simultaneously. The objective of investigation is to estimate interrelationships between grain protein content and some physiological indicators...

The topic of nitrogen wheat nutrition was becoming very actually during last decades of last century because of many reasons: fertilizers price, energetic crises, environmental protection, ecological agriculture. Despite the detrimental impacts, the use of fertilizers (N in particular) in agriculture, together with an improvement in cropping system...

Over the last few decades, wheat production, both in Serbia and worldwide, has been practiced under characteristic agrometeorological conditions. It has generally been affected by specific strongly marked agrometeorological and climate extremes, most notably extreme temperature and drought events during critical periods in the growing season, which...

The aim of study was to estimate interrelationship between efficiancy of dry matter accumulation (grain yield, biological yield) and some parameters of nitrogen accumulation efficiency (nitrogen content at above ground plant part in anthesis, grain, straw and whole matured plant) in winter wheat. The experiment was conducted as field trial, include...

Variability and components of variance for some dry matter status indicators (grain yield, biological yield and grain harvest index) have been studied in 30 winter wheat varieties from different selection centers (Morava, Lepenica, Studenica, Takovcanka, Toplica, Srbijanka, KG 100, Lazarica, Bujna, Matica, Vizija, Pobeda, Rana 5, Evropa 90, Renesan...

Considering the very important role of nitrogen in plant life cycle, parameters of plant nitrogen nutrition efficiancy represent a group of physiological traits suitable to contemporary wheat breeding aims. Theefore, the objectives of the study were to estimate variability of nitrogen nutrition efficiancy indicators and to estimate their heritabili...

Variability and components of variance for some dry matter status indicators (grain yield, biological yield and grain harvest index) have been studied in 30 winter wheat varieties from different selection centers (Morava, Lepenica, Studenica, Takovcanka, Toplica, Srbijanka, KG 100, Lazarica, Bujna, Matica, Vizija, Pobeda, Rana 5, Evropa 90, Renesan...

The topic of N wheat nutrition was prevalent during the last decades of the 20th century for many reasons such as energy crises, profitability of small grain production, and ecosystem protection and preservation. The objective of this study was to determine the interrelationships between wheat (Triticum aestivum L.) grain N content and other indica...

The topic of nitrogen for wheat nutrition has become quite important over the last few decades for many reasons. The most important are the energy crises and the escalation of the price of fertiliser, causing a decrease in profitability of small grains production and an adverse impact from the excessive use of nitrogen (N) fertiliser on the ecosyst...

This paper deals with interrelationship between grain yield and some physiological parameters of wheat plant nitrogen nutrition efficiency as well as interrelationships between these parameters and some yield related traits (biological yield, grain harvest index). The aim of such investigation is to affirm possibilities of using physiological param...

The aim of this study was to estimate components of phenotypic variability of some nitrogen status indicators in wheat. A field trial included 30 wheat genotypes. The N content at flowering in aboveground parts of the plants, grain, straw and whole matured plants, N harvest index, N reutilization, N post-anthesis accumulation and physiological effi...

This study examined the effect of mineral (NPK), organic (manure) and lime (Njival Ca) fertilisers on the uptake of nickel and lead and their contents in the kernel and the above- ground portions of winter small grains. The investigation was conducted under field conditions in a soil having acid reaction (pH(KCl) 4.20). The trial involved an examin...

Two years trial was carried out on the property of Small Grains Research Centre in Kragujevac. Six winter and six spring oat genotypes were investigated. The next traits: plants height, panicle lenght, ear number in panicle, grain number in panicle and grain weight in panicle were studied. Those morphologic traits influence the yield of grains. The...

The increased soil acidity is usually solved by applying liming as pedomeliorative technique that leads to its neutralisation. However, low pH values and increased content of mobile aluminum in deeper soil subsurface layers can be solved by selection, breeding and development of wheat genotypes with higher tolerance to these stress factors. The aim...
