candidate of biological science T. Narhan, candidate of agricultural sciences M. Yeryniak, candidate of agricultural sciences S. Lyfenko, academician, doctor of agricultural sciences Plant Breeding and Genetics Institute-National Center of Seed and Cultivar Investigations The purpose. To sum up results of long-term probes and to determine according to agronomic attributes difference and selection worth of perspective lines of wheat, derivants wheat-wild-rye amphiploid (WWRA). Methods. Field-for determination of productivity, autoadaptivity and resistance of material; laboratoryfor determination of merit numbers of flour and genetic formulas of locuses of reserve proteins of the subject of inquiry; statistical-for determination of reliability of the gained results. Results. The selection assessment of 2 perspective lines, derivatives of amphiploid Elytricum fertile in comparison with modern grades is made. Conclusions. Use in remote hybridization of WWRA Elytricum fertile can be successful for selection of winter soft wheat. The high-yielding variety created thus is entered in the State registry and used in primary and elite seeds growing and powered up in the further selection process.

Effect of phenylalanine and tryptophane on chlorophyll and phenolic content, and the antioxidant activity of sweet basil (Ocimum basilicum L.) under drought conditions

“…UA0102183) from Ukrainian GeneBank (Kharkiv) was examined, and it was found that it has Rht-B1b allele (Chebotar et al, 2009). In the PBGI, isogenic lines were created: Od.267 b -from crossing and backcrossing of the short-stem breeding line Er.4517/06 (created on the genetic background of Od.267) (Motsnyj et al, 2017) with the recurrent cultivars Od.267, Od.51 eby intermittent crossing (Od.51 × OSD) × Od.51 × 6) F ∞ (Chebotar et al, 2013). Microsatellite analysis revealed only 81.8% similarity between the Od.51 e isogenic and the Od.51 recurrent lines (Chebotar et al, 2009).…”

Development of Specific Thinopyrum Cytogenetic Markers for Wheat-Wheatgrass Hybrids Using Sequencing and qPCR Data

“…As a result, the genetic diversity of wheat shifted towards European germplasm, especially in Asian countries, and was accompanied by the loss of the local old varieties [ 2 , 5 , 6 , 7 ]. The introgression of agronomically valuable traits from the Triticeae wild species via wide hybridization has been proved to be one of the efficient tools to enrich wheat gene repertoire [ 6 , 8 , 9 ]. Thinopyrum (wheatgrass) species are widely used in wide hybridization of wheat as donors of tolerance to adverse conditions and disease resistance [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”
