“…Effects of seed rate on 1000-grain weight and grain specific weight were small and inconsistent (Gooding et al, 2002). Also, the highest kernel yield was achieved with sowing rate 600 germinable seeds m -2 (Kristó et al, 2007;Maric et al, 2008). On the other hand, various sowing rates had highly significant influence on the number of fertile tillers (Khaliq et al, 1999;Chaudhry and Hussain, 2001;Wajid et al, 2004), and that sowing rate influences mainly of number of spikes per square meter, which has the closest relationship to yield from all yield components (Spink et al, 2000;Guberac et al, 2000;Lloveras et al, 2004;Stougaard and Xue, 2004;Guberac et al, 2005;Lithourgidis et al, 2006;Ozturk et al, 2006).…”

“…Numerous studies have documented how N fertilization (Campillo et al, 2010;Hirzel et al, 2010;Zecevic et al, 2010;Nikolic et al, 2012), seeding rate, planting date, row spacing, and seeding depth affect yield and yield components of wheat (Wajid et al, 2004;Guberac et al, 2005;Schillinger, 2005;Kristó et al, 2007;Maric et al, 2008;Otteson et al, 2008;Valério et al, 2009). Seeding rates for winter wheat can vary widely due to differences in seed quality, planting conditions, planting dates and planting equipment (Lloveras et al, 2004).…”

Planting density is important factor which influence yield and quality of wheat (Triticum aestivum L.) For this reason, in scientific investigations is constantly investigated optimization of plant number per unit area. The objective of this study was to determine the influence of seeding rate in grain quality of winter wheat cultivars. The experiment was conducted with four winter wheat genotypes ('Ana Morava', 'Vizija', 'L-3027', and 'Perla') at the Small Grains Research Centre of Kragujevac, Serbia, in 3 yr at two seeding rates (SR1 = 500 and SR2 = 650 germinating seeds m -2 ). The 1000-kernel weight, Zeleny sedimentation, and wet gluten content in divergent wheat genotypes were investigated depending on the seeding rate and ecological factors. Significant differences in quality components were established between investigated seeding rates. The highest values of all investigated quality traits were established in SR2 variant when applied 650 seeds m -2 . Genotypes reacted differently to seeding rate. 'Perla' in average had the highest mean sedimentation value (42.2 mL) and wet gluten content (33.76%) in SR2 variant and this cultivar responded the best to seeding rate. Significant differences for sedimentation value and wet gluten content were found among cultivars, years, seeding rate, and for all their interactions. Also, ANOVA for 1000-kernel weight showed highly significant differences among investigated varieties, seeding rate and growing seasons, but all their interactions were not significant. In all investigated genotypes, better quality was established in SR2 variant when applied 650 seeds m -2 .

To satisfy future demands, the increase of wheat (Triticum aestivum L.) yield is inevitable. Simultaneously, maintaining high crop productivity and efficient use of nutrients, especially nitrogen use efficiency (NUE), are essential for sustainable agriculture. NUE and its components are inherently complex and highly influenced by environmental factors, nitrogen management practices and genotypic variation. Therefore, a better understanding of their genetic basis and regulation is fundamental. To investigate NUE-related traits and their genetic and environmental regulation, field trials were evaluated in a Central European wheat collection of 93 cultivars at two nitrogen input levels across three seasons. This elite germplasm collection was genotyped on DArTseq® genotypic platform to identify loci affecting N-related complex agronomic traits. To conduct robust genome-wide association mapping, the genetic diversity, population structure and linkage disequilibrium were examined. Population structure was investigated by various methods and two subpopulations were identified. Their separation is based on the breeding history of the cultivars, while analysis of linkage disequilibrium suggested that selective pressures had acted on genomic regions bearing loci with remarkable agronomic importance. Besides NUE, genetic basis for variation in agronomic traits indirectly affecting NUE and its components, moreover genetic loci underlying response to nitrogen fertilisation were also determined. Altogether, 183 marker-trait associations (MTA) were identified spreading over almost the entire genome. We found that most of the MTAs were environmental-dependent. The present study identified several associated markers in those genomic regions where previous reports had found genes or quantitative trait loci influencing the same traits, while most of the MTAs revealed new genomic regions. Our data provides an overview of the allele composition of bread wheat varieties anchored to DArTseq® markers, which will facilitate the understanding of the genetic basis of NUE and agronomically important traits.

“…Cultivars 'Parsi' and 'Sirwan' sown on 7 November in the 2013-2014 cropping season were the first two superior high yielding treatments, whereas 'Bahar' and 'Sivand' × 31 December × 2013-2014 were the worst treatments. It has been documented how sowing date can affect wheat yield and yield components of wheat (Kristó et al, 2007) as well as quality traits (Silva et al, 2014). Average kernel yield reduction of all the cultivars, measured under late and very late planting, was 34% and 50% of optimum sown (November) in 2013-2014, and 25% and 38% in 2014-2015, respectively.…”

The current study explored the effects of six spring wheat (Triticum aestivum L.) cultivars, four sowing dates (early, timely, late and very late) and their interactions on quantitative and qualitative traits during two cropping years. A combined analysis of variance (ANOVA) indicated that the effect of sowing date was significant on kernel yield and filling period. The quality traits were not significantly affected by the sowing date. Interaction of sowing date × cultivar × year was significant for some quantity and quality traits including yield, filling period, sedimentation value and gluten index. Average kernel yield reduction of all the cultivars, measured under late and very late planting, was 34% and 50% of optimum sown (November) in 2013-2014, and 25% and 38% in 2014-2015, respectively. For most of the studied traits, the effect of year was confirmed on higher level compared to the effect of cultivar or sowing date. The range for cultivar effect was high for thousand kernel weight, medium for gluten index and low for the other traits. The sowing date had the highest contribution to kernel yield followed by filling period and wet gluten, respectively. Negative relationship was observed between quality traits and kernel yield, but quality traits significantly and positively correlated with each other. In summary, the quality and quantity potential of wheat can be exploited by planting it at optimum time.
