The Stability

Aim. Cytological analysis of the stability of interspecific hybrids of wheat Triticum spelta L. x Triticum aestivum L. Methods. By the  method of temporal squashed preparations has been analyzed ploidy level, the frequency of structural chromosome aberrations and abnormalities  mitosis in root meristem cells of seedlings. Results. It was revealed that the F1 hybrids have significantly greater number of cells with impaired mitosis compared to the initial parental components. The vast majority of violations of the hybrids was represented by chromosomal aberrations. It is shown that the second-generation simple and bekrossing  hybrids   are characterized by  a certain stabilization of hybrid genomes, which manifests significant reduction in the number of abnormal mitosis. Conclusions. In interspecific hybridization spelled and soft wheat were found that when the maternal  component served as spelled and his father - soft wheat total the overall frequency of mitotic abnormalities was less than in the reciprocal crosses, which may be indicative of maternal cytoplasm effect.

In the present paper, we followed to determine the metal content in some different types of flour obtained from different wheat species, and in several pastes that contain flour made out of the Triticum aestivum, Triticum durum si Triticum spelta wheat species in their basic composition. In order to do this we have analyzed 10 samples: 2 flours and 8 pastes harvested from random stores, belonging to different local and foreign manufacturers. In the same time, we tryed to identify the wheat species used to produce the pastes, analyzing them depending on the metal content. The determination has been realysed using the atomic absorption spectrophotometric method, the analyzed metals being: Cu, Zn, Mn, Fe, Ca, Mg, K şi Na.

На Селекционной станции имени Н.Н. Тимофеева гибридизацией с донором устойчивости к пероноспорозу F1 Santero, беккроссом, инбридингом и отбором на инфекционном фоне с помощью молекулярного маркера DMR1 создано 15 линий лука репчатого гомозиготного по гену устойчивости Pd1. Оценка в однолетней культуре позволила выделить линии с массой луковиц 100120 г с высокой сохранностью, которые могут быть использованы в селекции F1 гибридов в качестве отцовских компонентов.Fifteen homozygous for Pd1 downy mildew resistance gene onion lines were developed by hybridization followed backcrossing F1 Santero of downy mildew resistant onion accession of European origin and a collection of onion inbred lines from LC Breeding station after N.N. Timofeev. The resistant to downy mildew, caused by Peronospora destructor (Berk.), plants were selected in segregated populations based on disease resistance test and molecular genotyping using DMR1marker. The lines with a mass of bulbs 100 120 g with high preservation, which can be used in the selection of F1 hybrids as paternal components.
