Aim. Triticale is one of the main grain crops of the Republic of Belarus. Further progress in the selection of this culture involves the accelerated creation of highly productive early ripening varieties resistant to abiotic and biotic factors. The method of induced androgenesis in vitro makes it possible to obtain stable homozygous lines in a short period of time and to eliminate the lengthy process of inbreeding used in classical breeding to fix the desired traits. Methods. The tissue and cell culture methods for plants was used in the study. Results. The influence of the induction medium composition on the efficiency of in vitro induced androgenesis in varieties and lines of hexaploid triticale is assessed. The influence of three types of induction culture medium, the type of phytohormones and the presence or absence of cefotaxime in the medium are analyzed. Results. It has been shown that using the C-17 culture medium supplemented with 2.0 mg/l 2,4-D and 0.5 mg/l kinetin without adding cefotaxime is most effective for the anther triticale cultivation. Keywords: triticale, anther culture, induction nutrient medium, embryoids, calli, regenerant plants, cefotaxime.

Aim. Testing the haploproduction ability of 47 varieties and 143 F1 hybrids of winter bread wheat. Methods. In vitro culture of isolated anthers of wheat. The percentage of callus and regeneration of green plants for each genotype calculated as a percentage of the planted anthers. Results. The differences in the frequency of сallus induction and the ability to regenerate plants in the process of androgenesiss in vitro of winter soft wheat were detected. The range of variation haploproduction activiti was broad. The sign of "the formation of сallus" for varieties was in limited from 0 to 21.2 % and for hybrids – from 0 to 38.8 %; on the sign of "regeneration of green plants" for varieties – from 0 to 9.4 %, and for hybrids from 0 to 9.1 %. The positive effect of 1BL/1RS translocation on signs of haploproduction in anther culture Triticum aestivum L. Conclusions. Genotype-specific of microspores morphogenetic reactions of soft winter wheat in the process of androgenesis in vitro were revealed. It has been found that F1 hybrids have a higher potential production potential in anther culture than varieties. During the period from 2011 to 2017, the 580 lines of winter wheat were transferred to the breeding departments. Keywords: soft winter wheat, anther culture in vitro, callus, regeneration.

Aim. Testing the haploproduction ability of 30 hybrids of winter soft wheat. Methods. In vitro culture of isolated anthers of wheat. The percentage of callus and regeneration of green plants for each genotype calculated as a percentage of the planted anthers. Results. The differences in the frequency of callus induction and the ability to regenerate plants in the process of androgenesiss in vitro of winter soft wheat were detected. The microspores of 17 of 30 hybrids formed callus by in vitro anther culture were shown. The intensity of one process was different: more than half of the genotypes (18 pcs.) were characterized by a low percentage of callus (from 0.10 to 1.0%), 6 genotypes - medium (from 1.0 to 3.0%), and three - high (4.36%; 15.11% and 15.81%, respectively). Conclusions. Genotype-specific of microspores morphogenetic reactions of soft winter wheat in the process of androgenesis in vitro were revealed Samples P26 and P27 showed the highest level of callus formation. The 10 green regenerating plants were obtained. Keywords: hybrids, soft winter wheat, anther culture in vitro, callus, regeneration.

Aim. To estimate the level of in vitro haploproduction androgenic ability of different generations populations (F1, F2) soft winter wheat hybrids of the same combination to maximize the use of biotechnology cereals. Methods. Obtaining of bread wheat double haploid lines by anther culture in vitro. The statistical methods. Results. The influence different generation of wheat hybrids on the processes of induction and regeneration in anther culture of winter bread wheat were studied. The 21 green plants-regenerants were received. Conclusions. The using of anthers of the second generation simple hybrids as donor material for the effective technology creation of doubled haploid of bread winter wheat was shown.Keywords: wheat, anther culture in vitro, callus, regeneration, generation simple hybrids.

Aims. To study the effect of chemically modified starch D–5aM in the culture medium on the efficiency of androgenesis in vitro in anther culture of rice. Methods. Obtaining of rice double haploid lines by anther culture in vitro. The statistical methods. Results The influence different variants of gellatyne source in culture medium on the processes of induction and regeneration in anther culture of rice were studied. The 119 green plants-regenerants were received. Conclusions. The negative effect on the formation of green regenerants using a gel-forming components of the chemically modified starch D–5aM was shown. Keywords: rice, anther culture in vitro, callus, regeneration, chemically modified starch.
