[Cytogenetic analysis of alloplasmic recombinant lines (H. vulgare)-T. aestivum with unstable fertility and viability].

Comparative cytogenetic analysis was performed with four alloplasmic recombinant (Hordeum vulgare)-Triticum aestivum lines differing in morphological traits, number of seeds per spike, and seed plumpness. None of the lines displayed introgression of the barley genetic material: the karyotypes included only common wheat chromosomes. Two lines, 79(B) and 79(D), were cytogenetically stable.

[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) x 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. (2n = 14) x Triticum aestivum L. (2n = 42), using molecular analysis and chromosome C-banding.

[Features of recombination of nuclear genome in back crossed offspring of barley-wheat hybrids Hordeum vulgare L. (2n=14) x Triticum aestivum L. (2n+42) with the use of SSR-analysis].

The backcross progenies of the barley-wheat hybrids Hordeum vulgare L. (2n = 14) x Triticum aestivum L. (2n = 42) and two alloplasmic lines derived from them were studied using microsatellite markers of barley and wheat.

[Study of the backcross progeny of barley-wheat hybrids by the RAPD and RAMPO methods].

The genomes of alloplasmic wheat lines were analyzed by PCR-based methods: random amplified polymorphic DNA (RAPD) and random amplified microsatellite polymorphism (RAMPO). Lines L-16(1) and L-17(2) were obtained by three backcrosses and line L-79(10), by four backcrosses of the barely-wheat hybrid Hordeum vulgare (2n = 14) (variety Nepolegayuschii) x Triticum aestivum (2n = 42) (variety Saratovskaya 29) with different common wheat varieties. These lines proved to be euploid (2n = 42).

[The clinical assessment of the results of predicting individual sensitivity to adjuvant chemotherapy in lung tumors].

The value of subrenal capsule assay for predicting individual chemoresistance of tumor was evaluated using samples from 32 lung carcinomas. Treatment with drugs which had proved effective in the test was followed by a recurrence-free period of 15.5 +/- 3.
