The occurrence of ergot [Claviceps purpurea (Fr.) Tul.] was studied in eight Lithuania-grown winter rye varieties at Šiauliai University’s Botanical Garden during the years 2002–2004. The source of infection consisted of ergot sclerotia incorporated in superficial layer of the soil between experimental plots of rye. Germination of ergot sclerotia and formation of ascocarps were assessed every three days from the first emergence of ascocarps over the soil surface. Percentage of flowering ears of rye was recorded every three days from the beginning of flowering of the first ears to the end of flowering. Percentage of ergot-infected ears and number of sclerotia per 1 m2 were estimated at rye hard maturity stage (BBCH 87). Averaged data from three experimental years suggest that local winter rye tetraploid variety Rûkai, characterised by late and lengthy flowering, exhibited the highest ergot susceptibility. Diploid varieties Duoniai and Joniai, flowering at a similar period as Rûkai, but having less expressed peak of flowering, were significantly less ergot – infected in 2002 and 2004, but in 2003 the occurrence of ergot on all the three varieties was similar. In our tests we did not reveal any increased ergot-susceptibility of the hybrid variety Esprit, although many authors indicate that hybrid varieties are the most susceptible to this pathogen. From the tested rye varieties, Walet, Motto and Hacada were found to be the least infected varieties, whose flowering was short and only a small number of ears flowered simultaneously. A strong negative correlation between crop density and ergot infection was established.

A two-factorial field experiment in a randomized subblock desing was performed in the years 2001-2003 on light soil. The aim of reasearches was qualification of fertilization of winter rye and of liming intervention's influence on formation of mobility manganese content (1 mol HCl-dm-3) in the soil and on the concentration and removal of this element from tested cultivars' yield. Balanced NPK fertilization (N - 90, P - 30, K - 72 kg-ha-1) was applied with and without liming (CaO 1.76 t-ha-1). The following fertilizers were applied: single-component fertilizers - ammonium nitrate (presowing fertilization), urea (top-dressing), triple superphosphate, 56% potassium salt; multi-component fertilizers - Polifoska 8, Polimag 305, Luboplon and Lubofoska. The soil after harvest of rye characterised with middle abudance in available manganese and according to cultivar fluctuated aproximatety from 121 to 151 mg Mn-kg-1. Although limmng interventions reduced the amount of this form of manganese it hasn't changed its class of resources. The last contents of manganese was stated in grain of hybrid cultivar Ursus F1, more in grain Dankowskie Złote and Nawid F1. Similar tendency showed concentration of manganese in rye straw. on removed manganese from plants' crop had influence both liming and cultivar. From testd cultivars the least of component was drawn by rye Dankowskie Złote - 175 g, more Ursus - 181 g and Nawid - 197 g Mn per ha.

The studies were carried out in Wielkopolska region (western Poland) in oat and winter rye cultures. Density and species structure of Thysanoptera were studied. Average density of adult Thysanoptera on oat reached 371.4 individuals/m2, and was higher than on rye, where it reached 107.5 individuals/m2. Limothrips cerealium Haliday was a dominant species on oat as well as on winter rye.

The values and variability of 21 traits in 99 hybrids and 21 population forms of winter rye were investigated together in the field and laboratory experiments performed in 6 localities in the years 2003-2005. It was observed that hybrid forms as compared to the population forms are characterizes by a higher crop uniformity of the corn field, higher weight of 1000 grains and resistance to lodging. On the other hand the population forms showed a better pollination of the inflorescences, higher resistance to stem and brown rust and higher protein content. Both forms also differed in the variability of the investigated traits. Hybrid forms were characterized by a higher variability of pollination of the inflorescences and resistance of brown rust while the population forms showed a higher resistance to lodging and stem rust.

Investigations on Fusarium head blight of rye were carried out in the years 2005-2007 on 10 production fields in the Lublin region. The percentage of heads showing the fusariosis symptoms in the years 2005-2007 ranged from 0 to 7%. Mycological analysis of kernels and chaff obtained from heads with Fusarium blight (scab) symptoms showed that Fusarium avenaceum, Fusarium culmorum and Fusarium sporotrichioides were the largest threat to heads of this cereal. The species of Fusarium poae and Fusarium crookwellense were also isolated from infected rye heads. The dominance of particular species in infecting rye heads was determined by weather conditions.

In the areas of winter rye cultivation in Lublin region, samples of winter rye grain and soil were collected for analysis. The study aimed at assessment of winter rye grain quality on the basis oil heavy metals (lead, cadmium, nickel, zinc, copper, arsenic and mercury) contents and finding the correlation among these heavy metals and some properties of soil and plant. Heavy metals contents were not significantly affected by the soil on which the rye was grown. None of the tested features did indicate significant relationship with the contents of these metals in grain. Dependence of heavy metals contents in grain on some elements occurring in this part of plant was significantly positive. This was indicated by statistical analysis showing that determination coefficients ranged within 5.5-40.4%. Multiple regression equations enable to forecast direction of changes in the contents of particular metals in grain as a consequence of occurring other elements in this part of plant. Contents of heavy metals in winter rye grain (0.156 mg Pb, 0.035 mg Cd, 0.503 mg Ni, 30.3 mg Zn, 3.168 mg Cu, 0.011 mg As, 0.00029 mg Hg·kg⁻¹ fresh matter) indicate that it was safe and didn’t exceed the upper threshold of contamination typical for products of this type.

The genetic variability between 5 open-pollinated varieties of rye (Secale cereale L) and between the components of rye hybrids was estimated using PCR-based marker analysis. The 22 maternal single crosses and 11 restorers were the components of hybrids investigated in the preofficial trials at the Plant Breeding and Acclimatization Institute in Radzików (PBAI), the Danko Breeding Co. Ltd (DBC) and in the Poznań Breeding Co. Ltd (PBC) during the 2001 growing season. The PCR system using semispecific primers targeting the intron-exon junction sequences of plant genes was applied for the evaluation of the genetic diversity of rye breeding materials. The genetic distances between varieties were relatively low; the coefficients of dissimilarity did not exceed 0.15. The highest average distance between maternal hybrids and restorers (0.28) was found in materials from PBAI, whereas in materials from PBC and DBC the average distances were lower and reached 0.21 and 0.20 respectively. The cluster analysis based on PCR data indicated that hybrid components that originated from different breeding centres exhibited different genetic characters.

В период 1978 - 1985 гг, проводились параллельно два полевых опыта заложенные на почве хорошего и слабого ржаного комплекса. В 4-польных севооборотах с повышающимся участием зерновых - 50, 75 и 100% исследовали урожайность озимой ржи, ярового ячменя и овса. На почве хорошего ржаного комплекса только рожь и ячмень и только в условиях монокультуры зерновых дали урожай в среднием на 14% ниже, гогда как на почве слабого ржаного комплекса все возделываемые виды реагировали отрицательно. Увеличение участия зерновых с 50 до 75% вызвало снижение урожая ячменя и овса на примерно 18%, а ржи на 12%. В монокультуре зерновых снижение урожая было сильнее, составляя в злучае ячменя 34%, а овса и ржи 23%.
