Seven triticale cultivars (Ampiac, Aubrac, Trinidad, Ticino, Lamberto, Pronto and Prado) and their F1 hybrids obtained after crossing in a line x tester scheme were examined with respect to their androgenetic effectiveness. The embryo induction rate (number of embryos per 100 anthers), green plant regeneration rate (number of green plantlets per 100 embryos), plant yield (number of green and albino plantlets per 100 anthers) and green plant yield (number of green plantlets per 100 anthers) were assessed. The multivariate and univariate effects of general (GCA) and specific (SCA) combining abilities for the studied traits were estimated and tested. Significant differences between the genotypes were found for individual traits as well as for all the traits treated jointly. Hybrids generally showed a better response in anther culture than their parental genotypes. Heterosis effects were observed in some hybrids for embryo induction rate and green plant yield. GCA and SCA variances were significant and a dominance of the GCA over the SCA variation was found. Among the examined cultivars, Ticino and Pronto were characterised by positive and significant GCA for embryo induction and green plant yield, and these cultivars may be recommended for the improvement of anther culture responsiveness in triticale.

Immature, mature and endosperm-supported mature embryos of six triticale cultivars (BDMT-98-8S, Melez-2001, Mikham-2002, Presto, Tacettin Bey and Tatlicak-97) were cultured in vitro to compare the levels of callus induction and plant regeneration. Immature embryos, 15-18 days after anthesis, were aseptically excised and placed with the scutellum upwards on a callus culture medium consisting of Murashige and Skoog (MS) mineral salts supplemented with 2 mg l-1 2,4-dichlorophenoxyacetic acid (2,4-D). Mature embryos were aseptically excised from the imbibed seeds and placed scutellum up on MS medium supplement with 2 mg l-1 2,4-D. Endosperm-supported mature embryos were moved slightly in the imbibed mature seeds. The seeds with moved embryos were placed furrow downwards in dishes containing 8 mg l-1 2,4-D for callus induction. The developed calli and regenerated plants were maintained on hormone-free MS medium. Variability among the genotypes was observed for all the types of embryo culture. Immature embryos from "Presto"and endosperm-supported mature embryos from "Mikham 2002" had excellent regeneration capacities (92.0% and 97.3%, respectively) and the highest number of plants regenerated growing in soil (9 and 13, respectively). A comparison of the responses of the three explants used indicated that the endosperm-supported mature embryo was the most useful explant for plant regeneration in triticale.

Determination of soluble protein amino acid content isolated from bird cherry leaves during the spring development (April-May) was done using of ion-exchange chromatography. The fifteen amino acids were identified and determined. It was affirmed that valine was predominant among the all studied amino acids. Obtained results indicate that during spring maturing of bird cherry leaves increases the soluble protein concentration and total amino acid content of analysed protein fraction. It was shown the occurrence statistically significant seasonal changes in the content of ten amino acids: aspartic acid, glutamic acid, lysine, phenylalanine, leucine, isoleucine, tyrosine, methionine, threonine and serine.

The objective of this study was to evaluate the usefulness of amplified fragment length polymorphism (AFLP) analyses for selection of the best parents for breeding of hybrid winter triticale. Phenotypic diversity was measured for 8 agronomic traits in 10 parents and 27 F₁ hybrids. Genotypic diversity was measured by 91 AFLP markers. Coefficients of correlation of genetic similarity (AFLP-GS) with both Euclidean distances and mean values of the traits were generally not significant. A correction of the preliminary binary matrix into trait-specific derived matrices increased the values of 5 correlation coefficients to a significant level. The correlation of AFLP-GS with mid-parent heterosis of grain weight per plant was low but significant (r = -0.452). Our study confirms the effectiveness of marker preselection for obtaining AFLP-GS better correlated with heterosis. The use of derived matrices is promising for reducing the number of cross combinations tested for specific combining ability.

The obtained results showed that grain aphid (Sitobion avenae Fabr.) feeding caused an increase of the total protein content and a decrease of soluble protein level in the ears of both studied winter triticale cultivars (i.e. susceptible cultivar Grado and relatively resistant- Lasko). Moreover, the content of amino acids in soluble protein increased in Grado plants infested with the aphid, and reduced - in Lasko.
