Aim. To explore sources of high groats properties among the genetic diversity of emmer and related species. Methods. Biochemical: The protein content was determined by Kjeldahl digestion; the starch content – by infrared spectroscopy. Technological: the vitreousness was determined by cutting 100 caryopses and expressed as percent- ages. The hull content, expressed in percent, was estimated as the ratio of hulled caryopses to the total of fully threshed ones. The gluten content and quality were assessed by manual washing-out. The hardness was determined on a YPD-300 hardness tester (Ltpm China) as the force in newtons required for caryopsis destruction. Emmer groats were obtained on a laboratory peeler UShZ-1. The groats properties were evaluated according to the method described in a utility model patent No. 129205. Statistical: the significance of differences between accessions was assessed using the Mann-Whitney test for small samples with unknown distribution. Two-factor analysis of vari- ance considered 2 factors – genotype and year conditions. Pearson’s test was used in the correlation analysis. The variability of traits was assessed by the coefficient of variation (CV). Results. The yields of emmer and durum wheat accessions and varieties as well as lines derived from emmer-wheat hybrids were measured and analyzed in 2016–2019. The yields of most emmer accessions (except for T. timopheevii) were similar to that of the check em- mer variety Holikovska (286 ± 15 g/m2). The highest contents of protein and gluten were found in T. timopheevii (18.1 ± 0.4 % and 40.5 ± 1.8 %, respectively), Triticum durum Desf. var. falcatomelanopus Jakubz. & Filat. (17.5 ± ± 1.0 % and 40.4 ± 1.4 %), autochthonous variety Polba 3 (16.8 ± 0.1 % and 36.9 ± 1.1 %), and line 10–139 (14.8 ± 0.8 % and 29.0 ± 2.4 %). The gluten quality of most lines, derived from crossing spring emmer with durum wheat, corresponds to quality group I (good), and the gluten deformation index (GDI) is 50–75 units. T. timopheevii and T. durum var. falcatomelanopus were noticeable for vitreousness (99 ± 1 % and 75 ± 5 %, respec- tively). The grain hardness of the accessions under investigation varied from 151 ± 15 N in variety Romanivska to 286 ± ± 3 N in T. timopheevii. Lines 10–79 (255 ± 6 N), 10–65 (220 ± 10 N) and T. durum var. falcatomelanopus (268 ± 6 N) were characterized by high hardness, which exceeded that of durum wheat variety Spadshchyna (152 ± ± 13 N). High outputs of groats were intrinsic to line 10–139 (96.2 ± 0.8 %), line 10–79 (90.6 ± 0.8 %), T. timopheevii (92.0 ± 0.1 %), and durum wheat Spadshchyna (91.4 ± 0.5 %). All the studied accessions showed low variability (

Background. The collection of durum wheat landraces (Triticum durum Desf.) at VIR contains unique material of the “Russian northern branch”, which is not found in any other collections worldwide. Studying the genetic diversity of such wheat accessions according to their gliadin bands as markers of genotypes is important for identification and conservation of their gene pool authenticity.Materials and methods. For the first time, molecular markers were used to differentiate among 38 accessions of the local durum wheat variety known under the name of “Kubanka”, collected and placed into the VIR collection in the 1910–1940s, and five accessions from the seed genebanks of the USA and Canada. Electrophoretic patterns of gliadin were used as markers of genotypes within the polymorphic cultivar. Recording bands in the form of “protein formulas” allows the researcher to evaluate the polymorphism of each accession and the diversity within the collection. Gliadin analysis was performed on single grains according to the standard method adopted at VIR and approved by ISTA.Results and conclusions. Fourteen major biotypes marked with gliadin bands were identified. Depending on the component composition of the α-zone encoded by alleles of the GLI-2A locus, biotypes were combined into 4 groups. Within the groups, biotypes are determined by alleles of the GLI-1A, GLI-1B, GLI2B loci. Genetically close monotypic accessions and polytypic ones incorporating 2 to 6 biotypes were identified. Group I is typical for the European part of Russia as well as for Kazakhstan and Kyrgyzstan. Accessions of this group can be attributed to the Volga steppe ecotype. Group II biotypes are widespread in Altai Territory, Orenburg and Astrakhan Provinces of Russia; Group III in Stavropol Territory, Russia, and Kyrgyzstan; Group IV only in Altai Territory. The greatest genetic diversity was exhibited by the ‘Kubanka’ accessions from Altai and Krasnodar Territories, and Kyrgyzstan.

<p class="4Body">Total Dray Matter (TDM), Photosynthetically Active Radiation Intercepted (PARabs), Water Consumption (WC), Water use- (WUE), Radiation use efficiency (RUE) and the Relation between Radiation Interception and Water Consumption for Durum Wheat were investigate under different irrigation amount (D<sub>1</sub>= 100 % ETc; D<sub>2</sub>= 70 % ETc; D<sub>3</sub>= 40 % ETc and D<sub>4</sub>= pluvial) and during three growing seasons (2005-2006, 2006-2007 and 2007-2008). Results showed that, the cumulative PARabs decreased with deficit irrigation. In fact, D<sub>1</sub> treatment recorded the highest cumulative PAR abs and the lowest marked under D<sub>4</sub> treatment. Similarly, TDM and RUE were decreased with deficit irrigation. The highest RUE observed under the D<sub>1</sub> (from 1.32 to 1.43 g MJ<sup>-1</sup>) and the lowest under D<sub>4</sub> (from 1.17 to 1.29 g MJ<sup>-1</sup>). However WUE increased with deficit irrigation. The highest WUE were obtained under the D<sub>4</sub> (from 3 to 4 kg m<sup>-3</sup>) and the lowest were observed under D<sub>1</sub> (from 2.8 to 3.1 kg m<sup>-3</sup>). Significant linear relationship was found between cumulative PAR abs and cumulative water consumption with a high correlation coefficient (R<sup>2</sup>) only under the two treatments D<sub>1</sub> and D<sub>2</sub>.</p>

Investigations were carried out in 2007-2009 on the plots of the Felin Experimental Station belonging to the University of Life Science in Lublin. The studies comprised two cultivation lines of durum wheat (<i>Triticum durum</i> L.): STH 716 and STH 717, as well as the 'Tonacja' cultivar of common wheat (<i>T. aestivum</i> ssp. <i>vulgare</i> L.). Two levels of chemical protection were applied in the cultivation: minimal and complex protection. Infection of wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Tottman's scale, 1987). After three years of study, the mean disease indexes for the analyzed wheat genotypes in the experimental treatment with minimal protection were 31.13, 30.43 and 38.83 for, respectively, the 'Tonacja' cultivar and the cultivation lines of <i>T. durum</i> STH 716 and STH 717. In the experimental combination with complex protection, after three years of study the disease indexes ranged from 25.26 (<i>T. durum</i> STH 716) to 30.83 (<i>T. durum</i> STH 717). The results of mycological analysis of diseased plants showed that <i>Fusarium</i> spp., especially <i>F. culmorum</i>, <i>F. avenaceum</i> as well as <i>Bipolaris sorokiniana</i> and <i>Rhizoctonia solani</i>, caused root rot and necrosis of wheat stem bases. The analyzed chemical protection levels did not significantly influence grain yield of the investigated genotypes of <i>T. aestivum</i> and <i>T. durum</i>.
