“…In crop rotations after preceding crop pea, in 2017 the statistically significant higher falling number was found out (426 s) than in 2016 (400 s) and the year 2018 (404 s) -Table 5, Table 11. These results correlate with those reported by Amiri et al (2018) who argued that the stress due drought resulted in a decreasing grain yield and at the same time an increasing of falling numbers. The results of Eljak et al (2018) indicated, that the falling number of wheat flours was significantly affected by the fertilisation and environmental conditions.…”

At the present time, crop rotations are constantly adapted to economic conditions and one or two main crops are grown in agricultural farms. This has a negative impact on the environment. The optimization of grain yield and quality of winter wheat are dependent not only on the appropriate crop rotation but also on the nitrogen fertilisation. The aim of this study was to examine the effect of crop rotations, fertilisation and preceding crop on grain yield and quality of winter wheat during the years 2015/2016 – 2017/2018. The grain yield of winter wheat after preceding crop pea in crop rotation with 40% proportion of cereals was statistically higher (5.91 t/ha) than in crop rotation with 80% share of cereals (5.55 t/ha). In the treatment with mineral fertilisation and organic manure Veget® incorporation, the grain yield was statistically higher (6.00 t/ha) than in the treatment with mineral fertilisation (5.50 t/ha). According the standard STN 46 1100-2:2018 based on the wet gluten content, the winter wheat grain was classified into the class E by mineral fertilisation + organic manure Veget® in all monitored years. In 2017 the winter wheat grain was categorized into the class P based on wet gluten content in crop rotations with 80% proportion of cereals in the treatment with fertilisers only after preceding crop winter barley.

“…Also TGW, protein content, and gluten content showed a moderate positive phenotypic association with GY. Several studies showed inverse relationship between grain yield and grain N concentration (Triboï et al, 2006; Amiri et al, 2018). They suggested that this inverse relationship is because the genetic variations in C assimilation are higher than those of N assimilation.…”

Tetraploid relatives of durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husnot) represent an important reservoir of economically useful genes for development of new wheat cultivars. Two field experiments were conducted at Foggia (Italy), in the 2004 to 2006 and 2012 to 2015 growing seasons. In the first, 77 Khorasan wheat [T. turgidum subsp. turanicum (Jakubz.) Á. Löve & D. Löve] accessions from 23 countries of four geographic regions (Africa, Asia, Europe, and others) were evaluated to explore breeding opportunities. Seven agronomic traits were used to describe the diversity among the accessions: days to heading (HT), plant height (PH), grain yield (GY), specific weight (SW) as an indication of the density of the grain, 1000-grain weight (TGW), protein content, and gluten content. The total Shannon–Weaver diversity index was used to estimate phenotypic diversity, which ranged from monomorphic for PC (0.39) to highly polymorphic for TGW (0.67). A high level of total variation (87%) was attributed to the within-region diversity. The accessions grouped into six clusters, and seven elite accessions were selected as parents for crosses with durum wheat. In the second experiment, ten parents (seven Khorasan accessions and three durum wheat cultivars) and 790 F6 recombinant inbred lines (RILs) from the different T. durum × T. turgidum subsp. turanicum crosses were included to study genotypic and phenotypic variability of the same agronomic traits, plus the susceptibility index (SI) for disease. The genotypic coefficients of variation were lower than the phenotypic ones for all of the traits, which showed an environment effect on expression of these traits. High broad-sense heritability (h2 b > 86%) was recorded for all traits, and high h2 b coupled with high genetic gain as percentage of the mean (ΔG) was observed for HT, PH, GY, and SW, and for SI. This suggests that selection for these traits will provide good responses. Four principal components explained 70% of the total variation, and the genotypes were clustered into 20 groups. According to the results, some lines could be tested in varietal registration trials, and/or could be used as a significant breeding pool for durum wheat cultivar development in Mediterranean area.

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.
