“…Earlier, we reported the production of recombinant alloplasmic lines of bread wheat derived from backcross progenies of barley-wheat hybrid H. vulgare × T. aestivum and restoration of their fertility [10,11]. Alloplasmic (H. vulgare)-T. aestivum lines characterized by different fertility levels proved to be valuable models for studying the variability of both nuclear and organellar (mitochondrial and chloroplast) genomes in the process of nuclear-cytoplasmic co-adaptation as a result of backcrossing wide hybrids with paternal genotypes [12][13][14].…”

One of the limitations in obtaining the genetic diversity of doubled haploid (DH) lines via anther culture is the development of families of regenerants, and each family represents a clone. This work examines the results of studying this phenomenon in anther culture of alloplasmic (H. vulgare)–T. aestivum and euplasmic lines with 1RS.1BL and 7DL-7Ai translocations and hybrids between them. Parameters of androgenesis such as the number of embryo-like structures, the total number of regenerants, and the number of green regenerants per 100 anthers varied depending on the genotype. In all genotypes from embryo-like structures, predominant development of families of plantlets rather than single plantlets was found. The source of family plantlets was polyembryos. About 75% of families consisted of regenerants at the same fertility level. On average, 37.74%4% of the R0 plants were fertile. The sister DH lines of three hybrid combinations were formed from seeds of R1 plants (2n = 42) with high fertility and in the presence of wheat–alien translocations. After four years of breeding trials, the sister DH lines of three families with fungal disease resistance increased yield, and some parameters of grain quality exceeding the controls were identified as promising for breeding.

Long-term pea callus cultures of different genotypes (mutants R-9 and W-1 and cultivar Viola) were used to regenerate plants (generation R 0 ). The regenerants displayed changes both in qualitative and in quantitative traits. The most dramatic morphological alterations and complete sterility were observed in regenerants of the cultivar Viola. To estimate the genetic differences, regenerants were compared with the original lines with the use of RAPD (random amplified polymorphic DNA) and ISSR (inter simple sequence repeat) analyses. The extent of divergence varied among regenerants and depended mostly on the original genotype. The genetic difference from the original line was no more than 1% in W-1 regenerants, 0.7-5.3% in R-9 regenerants, and 10-15% in sterile regenerants of the cultivar Viola. The genetic variation of plants regenerated from a callus culture maintained for ten years did not exceed that of plants obtained from a culture maintained for two years. PLANT GENETICS

Molecular study and C-banding of chromosomes in common wheat alloplasmic lines obtained from the backcross progeny of barley?wheat hybrids Hordeum vulgare L. (2n = 14) � Triticum aestivum L. (2n = 42) and differing in fertility

We studied common wheat alloplasmic lines differing in fertility traits, which had been obtained from the backcross progeny of barley-wheat hybrids Hordeum vulgare L. (2 n = 14) × Triticum aestivum L.(2 n = 42), using molecular analysis and chromosome C-banding. It was found that the nuclei of all alloplasmic lines studied, regardless of their fertility traits, contained only the common wheat chromosomes (2 n = 42). The formation of line L-79(10)(3)F 6 , stable for self-fertility, from line L-79(10)F 3 was accompanied by changes of the proportions of simple sequence repeats of the parental common wheat varieties in the nuclear genome. The presence of barley genome fragments in line accessions with incomplete self-fertility was shown by RAPD. Heteroplasmy for mitochondrial genome loci was detected in these lines with the use of primers specific to the tMet-18S-5S repeat of mitochondrial ribosomal genes.
