    ABSTRACT: The study was conducted on the in vitro pollen germination at 26°, 28°, 32° and 35°C for 24h of male parental lines, pollen tube growth in vivo in cross pollination of female and male parental lines that make couples in four hybrids: ZP 504 su (� ZPPL 51 × � ZPPL 67); ZP 677 (� ZPPL 17 × � ZPPL 201); ZP 704 (� ZPPL 109 × � ZPPL 79), ZP 611 k (� ZPPL 126 × � ZPPL 105), and the open pollination of female parental lines of the above mentioned hybrids. Pollen germination in vitro and pollen tube growth dynamics in vivo showed different genotypic specificities with the tests applied. The obtained results were discussed in the context of reproductive biology of ZP maize lines and aimed to create the preconditions for successful management and direction of the process in practice - seed production in certain environmental conditions

    ABSTRACT: The objective of the present study was to observe and compare properties of nine maize hybrids biomass in order to determine their suitability for animal feed production. Yields, structure of the dry matter of the investigated maize hybrids, as well as the yield of the digestible dry matter were determined in maize hybrids harvested in the full waxy maturity stage. The content of lignocellulosic fibres, their respective ratios and the in vitro dry matter digestibility of the whole maize plant as well as the neutral detergent fibre digestibility (NDFD) were established. The results indicated significant differences in dry matter in vitro digestibility of the whole plant among different hybrids in the most optimal harvest stage. The whole plant dry matter digestibility of the investigated maize hybrids ranged from 59.67 to 65.53%. Very significant positive correlation was determined between NDFD and in vitro dry matter digestibility of the whole maize plant (r=0.66). Biomass of the selected maize hybrids was rated as feed of high quality and can, therefore, be used for animal feed production in different ratios depending on animal species, category and dietary needs. Keywords: maize hybrids, biomass, pepsin-cellulase in vitro dry matter digestibility, animal feed INTRODUCTION

    ABSTRACT: In the process of plant breeding the application of relevant breeding criteria is very important. The Path analysis is broadly applied with the aim to define yield components that mostly determine the yield and that can be used as quality breeding criteria. However, the significance of revealed relationships between yield and yield components can be affected by various factors, such as diverse genetic material that is observed, traits included into analysis, environments in which the material is observed, as well as, the applied statistic approach to determine the nature of the relationships itself. The interrelationships of yield and yield components of 15 commercial maize hybrids were observed using the Path and factor analyses. According to results of Path analysis, plant height, ear diameter and grain moisture had highly significant genetic and phenotypic direct effects on grain yield. At the same time, factor analysis points out significant effects of two factors on grain yield. Factor 1 was mostly determined by ear length and number of kernels per row, while grain moisture content, ear and cob diameter mostly determined Factor 2.

    ABSTRACT: There is a growing trend in production of early maturity maize hybrids as far north and on higher altitudes as possible, even in regions where they were not previously cultivated. Thus, an increased demand at the global market for early maturity maize hybrids of FAO 100 and 200 is present. These hybrids are able to mature under not so favourable temperature conditions. The experiments were performed in Planinica-central part of Serbia at 650 m above sea level, during four years (2001-2004). Nine Zemun Polje (ZP) dent and nine flint hybrids of the FAO 100 and 200 were observed. The highest average grain yield (7.19 t ha-1) was recorded in 2002 and it was also high in 2004 was (7.18 t ha-1), while in the remaining two years, yields were significantly lower (6.50 t ha-1-2001 and 4.32 t ha-1-2003). In more productive years two dent hybrids: ZP 290 (9.90 t ha-1 in 2002) and ZP 251 (10.22 t ha-1 in 2004) gave highest yields, while under less favourable weather conditions two flints ZP 114 (7.45 t ha-1 in 2001) and ZP 125 (5.40 t ha-1 in 2003) were most productive. Flint hybrid ZP 115 (7.22 t ha-1) was the highest yielding, on average. Also, high average yields were observed in two dent hybrids ZP 290 (7.10 t ha-1) and ZP 248 (6.88 t ha-1), and one flint ZP 246 (7.09 t ha-1). Thus, these four early maize hybrids were characterized as genotypes of high yielding potential.

    ABSTRACT: 2013): Variability of factors that affect availability of iron, manganese and zinc in maize lines. Genetika, Vol 45, No. 3, 907-920 Deficiencies of some mineral elements are causing serious health problems, which could be prevented by increase of mineral nutrients in food with supplementation, food fortification or plant breeding. From this point, experiment with 78 maize inbred lines was set up to determine maize lines with improved contents of Fe, Zn and Mn, as well as their relations with phytic acid, inorganic phosphorus and β-carotene, as factors which affect their absorption. Obtained results suggest that investigated maize lines show high variability in concentration of Fe, Mn and Zn, as well as phytic acid (which sustain availability of mineral elements) and β-carotene (which enables better absorption of mineral element and minimize negative effect of phytic acid). From this point of view, group of genotypes with phytic P ≤ 3 g kg -1 was interesting. Among them, L2 and L23 are maize lines with relatively high inorganic P, Fe and Zn contents, and together with relatively low ratio between phytic and inorganic P, they could be used as a good source of P, Fe and Zn. On the other hand, L1 and L4 are also maize lines with high inorganic P, β-carotene and Mn, and favourable ratio between phytic acid and Fe and Zn, what could give them advance as source of Mn in breeding programs. The same maize lines could also be candidates with improved ability for Fe and Zn absorption, what is based on high β-carotene content. Maize line L14, with relatively high concentration of all three Key words: maize lines, microelements, phytic acid, β-carotene INTRODUCTION For normal functioning, human body needs more than 22 mineral elements, which can be provided by an appropriate diet. Some diets, based on cereals and legumes, as well as foods produced on soils deficient in some minerals, could cause serious health problems. These

    ABSTRACT: The aim of research was to establish the influence of seed size on grain weight per spike of three wheat varieties. A trial was set up using split-plot method in four replications in Pančevo in the period 204 -2006. The seed was divided according to the size in four fractions: 1.8, 2.0, 2.2, 2.5 and 2.8 mm. A significant interaction was determined between the tested varieties and the years of testing, whilst a highly significant interaction was determined between the years of testing and the seed size, the varieties and the seed size, between the tested varieties, the years of testing and the tested seed size. The highest grain weight per spike was determined in PKB-Christina variety (2.29 g), and Pobeda variety (2.25 g), whilst Vizija variety had the lowest grain weight per spike (2.11 g). The difference was highly significant. The analysis of variance determined a highly significant difference between the years when the experiment was conducted, which is often seen in this region. Highly significant differences in the grain weight per spike were determined at different seed sizes. Larger seeds produced higher grain weight per spikes, highest weight being obtained with largest seeds (≥2.8 mm).

    ABSTRACT: A trial was set up in field conditions during 2003/04-2005/06 with seven different treatments of seed protection and three winter wheat varieties. Vizija variety had lower mass of 1,000 grains in comparison with Pobeda and PKB-Christina varieties, the difference being highly significant. By changing seed protection mode, the mass of 1,000 grains changed. A highly significant difference was established between control (39.8 g) and the variants treated by diviconazole (41.5 g). However, the mass of 1,000 grains of variants treated by difeconazole, carboxine + tiran and tebuconazole + triazoxine was at the level of controls and significant differences among these treatments were not determined. Treatment of electronic seed protection by means of plasma electrons showed significantly lower mass of 1,000 grains than it is the case of fungicidal protection by diviconazole, being on the level of control. Highly significant differences were established between years when the research was performed. High interactions between variety x years, variety x treatment, year x treatment and variety x year x treatment, were established. Strong positive correlation was established between mass of 1000 grains and wheat yield.

    ABSTRACT: Maize is one of the most important naturally renewable carbohydrate raw materials. The basic chemical composition (content of starch, protein, oil, crude fibre and ash) and the content of lignocellulose fibres (content of NDF, ADF, ADL, hemicelullose and cellulose) were determined for grain and the whole maize plant of the seven ZP maize hybrids. The negative very significant correlation between protein and starch content (r=-0.78) and significant correlation between oil and starch content (r=-0.65) was obtained in grain. The hybrid ZP 666 had the highest starch, crude fibre, ADF and cellulose content, high NDF content, the lowest ADL and low protein content in grain. The lowest starch, crude fibre, ADF, cellulose content and the highest protein and oil content in grain was determined in hybrid ZP 158. The hybrid ZP 730 had the highest and hybrid ZP158 the lowest dry matter yield of whole plant, whole plant without ear, ear and yield of digestible dry matter of whole plant. The differences in the contents of NDF, ADF, ADL, hemicelluloses, cellulose and digestibility of the whole maize plant among observed ZP hybrids were 6.21%, 4.01%, 0.79%, 5.65%, 3.88% and 6.79%, respectively. Obtained values for the content of lignocellulose fibres differed significantly among hybrids and were closely related to digestibility.
