“…Significant genetic variation among spring wheat cultivars for number of spikes m −2 , as well as its differential production at test locations, have also been previously reported by Lungo et al (1990). Grains spike −1 and harvest index were found significant in other studies conducted by Ansari et al (1989) and Dimitrijevic et al (2000).…”

While evaluating genotypes for yield in multi-environment tests, the variation can only be observed in the relative yield performance of genotypes across environments. Eighteen (18) wheat genotypes, along with two standard farmer check varieties, were tested under normal and late sowing conditions for yield comparison, heritability, and selection response to understand the causes of G × E interaction and identification of specific desirable traits and genotypes. Analysis of variance showed highly significant differences (P < 0.01) for spikes m −2 , seed yield, and harvest index, while significant differences (P < 0.05) were observed for spikelets spike −1 and grains spike −1. The environmental component revealed highly significant differences (P < 0.01) for all traits except for grain weight spike −1 , which exhibited significant differences (P < 0.05). However, the G × E interaction showed highly significant differences (P < 0.01) only for harvest index. The better accessions may further be tested for performance under late sowing conditions. The accessions also have potential for utilization in breeding programs for accumulating the genes of interest in genotypes which otherwise failed to perform better in late sowing environments. The selected accessions can be extremely useful for breeding cultivars to fill the gap between cultivars under conditions of very early or very late sowing.

“…Different values of spike traits in the same cultivars in different experimental years were also found in other studies which indicated a high influence of agro-ecological factors on the expression of spike traits (Agoston and Pepo, 2005;Dakhim et al 2012). High importance in establishing a response of genotypes to environmental conditions is given to research on the stability of yield and yield components (Dimitrijević et al, 2011).…”

three experimental years under different environmental factors. The experiment was set up as a randomized block design in three replications. Differences in the average values of grain weight spike-1 among tested cultivars were determined in all three years. On average, for all genotypes, grain weight spike-1 was highest (2.32g) in the first experimental year (2005/06), and lowest (1.95g) in the second year (2006/07). For all investigated wheat cultivars, in the third experimental year, the average value of grain weight spike-1 was 2.24g, while the total average value for all cultivars and three experimental years was 2.17g. 'Ana Morava' had the highest average values for grain weight spike-1 in all three experimental years, while the lowest grain weight spike-1 was obtained in 'Balkan' (1.81g) in the second year 'Lasta' (1.40g) and in the third experimental year 'Partizanka' (1.91g). On average, 'Ana Morava' had the

“…The grain yield of wheat depends on components such as the number of plants per m 2 , number of spikes per m 2 , number of kernels per spike, kernel weight in the spike, and the 1000kernel weight. The interactions between these parameters are complex, thus the increase in values of a single parameter decreases the value of another parameter (Laghari et al 2011;Perišić et al 2011;Dimitrijević at al. 2011;Hristov et al 2012;Milovanović et al 2012;Đekić et al 2012;Hassan et al 2013;Mohamed et al 2013;Hagos and Abai, 2013).…”

“…The question of the importance of the seed size is still discussed. Madić et al (2010) and Dimitrijević et al (2011) have studied variability and stability of yield components of many wheat varieties. These authors determined the significant effect of varieties, years and their interactions on the expression of traits.…”

The aim of the research in field conditions was to establish grain yield and some yield components in three wheat varieties depending on seed size, 1.8, 2.0, 2.2, 2.5 and 2.8 mm, using split-plot method in four replications. The highest number of plants (477 and 518) per m 2 was obtained from the 2.5 and 2.8 mm seed size, respectively. The largest number of spikes (561 and 532) per m 2 was obtained from the 2.8 and 2.5 mm seed size, respectively. The highest coefficient of productive tillering of 1.39 was recorded in the 1.8 mm seed size. Remaining seed fractions (2.0, 2.2, 2.5 and 2.8 mm) gave significantly lower productive tillering. There were very significant differences in wheat grain yield over years, varieties, seed sizes and the year × seed size interactions. The highest wheat grain yields of 7.22 t ha-1 and 6.86 t ha-1 were achieved in the case of 2.5 and 2.2 mm seed sizes, respectively. A positive strong correlation was detected between the number of overwintered plants and the grain yield (r = 0.63**). Moreover a positive strong correlation was established between the number of spikes and the grain yield (r = 0.70**), while the negative weak correlation was recorded between the coefficient of productive tillering and the grain yield (r =-0.32**). With the same sowing norm, a large seed produces a significantly higher number of plants and spikes per m 2 than small seed, which is important for the grain yield.
