Opis:: F₁, F₂ populations as well as F₃ and F₄ wheat lines coming from more than 300 cross combinations have been used for androgenic wheat studies and more than 5000 haploid plants were produced. Promising doubled haploid lines were tested together with lines produced in the conventional way in yield trials. The two best doubled haploid lines overyielded the standard. On the basis of results related to the general combining ability it is advisible to cross parents with a good combining ability for characters such as high percentage of responding anthers and embryo/callus induction with parents indicating a good combining ability for green plant production. In this way ideal lines can be obtained for doubled haploid production.

Opis:: The paper deals with evaluating the yield and yield structure elements of winter durum wheat lines (Triticum durum Desf.) under conditions of varied levels of chemical protection. The field experiments were carried out in 2006-2008 on the Experimental Farm Felin, University of Life Sciences, Lublin. Examinations involved 3 lines of durum wheat (STH 716, 717, 725) achieved from Plant Breeding Station in Strzelce as well as common wheat Tonacja cv. for comparison. The second factor consisted of 2 levels of chemical protection: I – minimum (seed dressing Oxafun T 75 DS/WS and herbicide Chwastox Trio 540 SL); II – complex (seed dressing, herbicides Puma Uniwersal 069 EW and Chwastox Trio 540 SL, fungicide Alert 375 SC, growth regulator Stabilan 750 SL and insecticide Decis 2,5 EC). Obtained results allowed for concluding that when comparing with minimum protection, the increase in wheat grain yields by 1.08 t·ha-1 was recorded on complex-protected treatments, regardless of compared lines and varieties. Lower yield of durum wheat as compared to common wheat resulted first of all from lower spike density per area unit. A positive influence of chemical protection on spike number and grain number per spike was observed. Durum wheat lines were characterized by high grain vitreousness.
W pracy dokonano oceny plonowania i elementów struktury plonu 3 linii ozimych pszenicy twardej Triticum durum Desf. w warunkach zróżnicowanego poziomu ochrony chemicznej. Badania polowe przeprowadzone w latach 2006-2008 objęły linie STH 716, 717 i 725, które otrzymano w Stacji Hodowli Roślin w Strzelcach i odmianę pszenicy zwyczajnej Tonacja. Stosowano 2 poziomy ochrony chemicznej: I – ochrona minimalna (zaprawa nasienna Oxafun T 75 DS/WS i herbicyd Chwastox Trio 540 SL), II – ochrona kompleksowa (zaprawa nasienna, herbicydy Puma Uniwersal 069 EW i Chwastox Trio 540 SL, fungicyd Alert 375 SC, regulator wzrostu Stabilan 750 SL i insektycyd Decis 2,5 EC). W porównaniu z ochroną minimalną na obiektach chronionych kompleksowo otrzymano wzrost plonu ziarna pszenicy o 1,08 t∙ha-1, niezależnie od porównywanych linii i odmian. Średni plon ziarna badanych linii pszenicy twardej – 5,82 t·ha-1 należy uznać za dobry, jednak w porównaniu z pszenicą zwyczajną stanowił tylko 66% jej plonu. Niższe plonowanie pszenicy twardej w porównaniu z pszenicą zwyczajną wynikało przede wszystkim z niższej obsady kłosów na jednostce powierzchni. Stwierdzono korzystne oddziaływanie ochrony chemicznej na liczbę kłosów oraz liczbę ziarn z kłosa. Linie pszenicy twardej wyróżniały się wysoką szklistością ziarna.

Opis:: Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez; (3) the Pch3 gene, originating from Dasypyrum villosum; and (4) the Q.Pch.jic-5A gene, a quantitative trait locus (QTL) located on chromosome 5A of Capelle Desprez. However, those loci have drawbacks, such as linkage of Pch1 with deleterious traits and limited effectiveness of Pch2 against the disease. Here we present an initial study which aims to characterize wheat pre-registration breeding lines carrying 12 eyespot resistance genes, consider their resistance expression in inoculation tests and the influence of resistance genotypes on the yield. We selected four groups of breeding lines, carrying: (1) the Pch1 gene alone: one line; (2) the Pch2 gene alone: four lines; (3) the Q.Pch.jic-5A gene alone: one line; and (4) Pch1 + Q.Pch.jic-5A: three lines. For the first time, the effect of the combination of Pch1 and Q.Pch.jic-5A genes was compared with resistance conferred by Pch1 or Q.Pch.jic-5A alone. We found significant differences between infection scores evaluated in resistant lines carrying Pch1 and Q.Pch.jic-5A alone, while no differences in terms of the level of resistance expression were detected between Pch1 alone and Pch1 + Q.Pch.jic-5A, and between wheat lines carrying Pch1 and Pch2 alone. Moreover, we demonstrated that the Pch1 gene, together with an Ae. ventricosa segment, caused statistically significant yield losses, both as a single eyespot resistance source or in a combination with Q.Pch.jic-5A. Yield scores showed that wheat lines with Q.Pch.jic-5A had the highest yields, similar to the yielding potential of Pch2-bearing lines and control varieties.

Opis:: The paper concerns the influence of added rye chromosomes on physical properties of kernels of the addition lines T. eastivum Grana - S. cereale Dańkowskie Złote 1R", 2R", 3R", 3RS", 4R", 5R", 6R", and 6RL", as well as initial forms: wheat cv. Grana, rye cv. Dańkowskie Złote and octoploid triticale Grana × Dańkowskie Złote. Kernels from each form, were analysed for the following features: basic geometric dimensions of kernels, 100-kernel weight and kernel volume; surface roughness, index of kernel damage and mechanical strength (determined by maximum force, force within elasticity limits, maximum deformation, elastic deformation, energy causing deterioration of kernel structure). Wheat lines with added rye chromosomes differed from one another and from the initial form wheat cv. Grana in basic geometric dimensions. The lines 6R" and 6RL" had a distinctly higher 100-kernel weight and kernel volume than their initial forms. All the addition lines and octoploid triticale were characterised by markedly higher indices of external damages than the wheat cv. Grana. The mechanical strength of addition line kernels also varied considerably.

Opis:: Eyespot is one of the most important fungal diseases of the stem base of wheat (Triticum aestivum L.). The presented study clearly demonstrated that the Pch1 gene was the main effective source for reducing the eyespot disease score in the analyzed winter wheat lines. Nevertheless, Pch1 was present only in 8−9% of the investigated lines. Using an isoenzymatic marker and molecular markers, the presence of the Pch1 gene and lack of the Pch2 gene was identified in six lines. Two lines, SMH 9409 and DL 358/13/4, were polymorphic in an isoenzymatic marker study. In the remaining three lines, C 3373/11-1, KBH 15.15 and KBP 1416, the Pch1 gene was identified only with the use of an isoenzymatic marker. Both genes Pch1 and Pch2, as well as the resistant variety Rendezvous, were found in three lines: DD 248/12, KBP 15.2 and STH 4431. In line DD 708/13, the presence of the Pch1 and Pch2 genes was identified, where the association between the Pch1 and the locus of the Xorw5 marker was broken. It was shown that the presence or absence of Pch1 and Pch2 genes did not significantly affect the grain yield (from the plot), although the yield was highest in the presence of both genes. A significant effect of the presence of the Pch1 gene on thousand kernel weight (TKW) was observed. Lines with the Pch1 gene showed significantly higher TKW values than lines without both genes or with the Pch2 gene only.

Opis:: Parametry kolorymetryczne: indeks zażółcenia YI i odległość barwy ΔE* od wzorca, zastosowano do opisu barwy semoliny uzyskanej z ziarna pszenicy polskich linii hodowlanych. Celem poprawienia precyzji oznaczeń na spektrofotometrze odbiciowym, zmielone na młynku tarczowym próbki ziarna przygotowywano w postaci pastylek, stosując ciśnienie 50MPa. Otrzymano wysokie wartości indeksu zażołcenia - świadczące o dużej zawartości karotenoidów w ziarnie polskich linii hodowlanych i odpowiadające wartościom zbliżonym do próbek ziarna importowanego. Na zanieczyszczenie miewa elementami okrywowymi z ziarna wskazywała znaczna odległość barwy (ΔE*) i obniżona jasność barwy (L*).
The colorimetric parameters such as yellowness index (YI) and the total colour difference (ΔE*) between the standard and the tested sample have been applied for the colour description of semolina obtained from Polish breeding wheat lines (Triticum durum). In order to improve the precision of determination using reflectance spectrophotometer, the samples grinded in disk mill have been pressed (50 MPa) into a cake. Bigh values of Yl, reflecting large amount of carotenoids, found for Polish wheat were approximately equal to Yl values of imported grains. Increased color differences (ΔE*) and decreased lightness (L*) have pointed to meal contamination with bran particles.
