Aim. Evaluation of innovative methodological approaches elaborated on model genotypes for usability to increase frequencies of morphogenic structure induction and plant regeneration in anther culture in vitro in spring barley diverse material. Methods. Spikes isolated from F1 and F2 hybrids of four crosses were pretreated using an improved method (4ºC, 28 days), and anthers were inoculated onto nutrient media containing chemically modified starches D5-M and D5a-1 instead of agar. In control cut tillers were emerged in water and pretreated at 4ºC for 5 days. Anthers were cultivated on agar solidified medium. Results. Positive effects of the improved method of cold pretreatment and cultivation of anthers on media solidified with starches were confirmed. The advantage of new gelling agent D5a-1 was proved. Particularly, its usage resulted in a three-fold increase in the frequency of green plant regeneration. Conclusions. In order to increase spring barley androgenic haploid yield, combination of prolonged cold pretreatment with anther cultivation on media solidified with chemically modified starches instead of agar in an integrated technological process is reasonable.

Morphological variability of haploid plants and doubled haploids of rice obtained on one callus line in anther culture in vitro was studied. The work was carried out on rice plants Oryza sativa L. subspecies japonica Kato varietу Cascade. Regenerant plants of one callus line obtained from one rice anther (four in total) were divided into two or three groups of 20-30 plants, depending on the sample size in order of their differentiation on callus and transplantation on the rooting medium. Two callus lines (15.1 and 18.1) formed half of the haploids, half of the doubled haploids, and two other callus lines (5.1 and 7.2) numerous haploids. On callus lines with numerous haploids (5.1 and 7.2), as the regenant number increases, the size of plants decreases (plant height, number of flowers on the main panicle, number of panicles). On the lines 15.1 and 18.1 between groups of haploids and between groups of doubled haploids statistically significant differences absent. In breeding purposes for the induced doubling of the number of chromosomes in haploid regenerants with antitubulin substances such as colchicine, it is advisable to use plants that form on callus among the first. Between haploids of four callus lines and doubled haploids of two callus lines, statistically significant differences (at p=0.001) were revealed using the Hotelling's T2-criterion, calculated for the whole complex of biometric features. Haploids of different lines differed in three or four of them, doubled haploids on three of the five signs (length of panicle, productive bushiness and plant height). Varieties of interest to breeders may be improved by anther culture in vitro.

The objective of the study was to investigate efficiency of anther culture in the production of spontaneous double haploids from randomly selected heterozygous genotypes of wheat (Triticum aestivum L.). Anthers of 20 F1 wheat combinations were grown in vitro on a modified Potato-2 medium. All of the examined genotypes have shown the ability to produce pollen calluses as well as to regenerate green plants. On average for the whole experiment material, 47.2 calluses were produced per 100 cultured anthers. The green plant regeneration ranged from 0.8 to 13.4 green plants per spike, with an overall mean of 5.8. From the total of 582 regenerated green plants, 47.9% (279) were spontaneous double haploids. The final average yield from the study was 2.8 double haploids per spike.

We investigated the anther culture (AC) efficiency of thirteen F<sub>4</sub> combinations of winter wheat (Triticum aestivum L.). The genotype dependency was assessed during the induction of the androgenic entities, i.e. embryo-like structures (ELS), regenerated-, green-, albino-, and transplanted plantlets. The number of green plantlets per 100 anthers (GP/100A) varied from 0.36 to 24.74 GP/100A with a mean of 8.31 GP/100A. Albino plantlets (AP) occurred in each combination, ranging from 0.20 to 22.80 AP/100A with an average value of 5.59 AP/100A. Between 25–87.76 doubled haploid (DH) plants per 100 acclimatised plantlets (DH/100ADP), depending on the combination, with a mean of 59.74% were recovered. We have found the highest DH production in the combinations Béres/Midas, Kalász/Tacitus, Béres/Pamier, and Premio/5009. This improves remarkably the choice of basic genetic material in subsequent crossing programmes. These observations emphasise the usability and efficiency of in vitro AC in producing a large number of DH lines for breeding and the applied researches of winter wheat. Although albinism was found in each combination, it was mitigated by the in vitro AC application.
