“…The ideotype of a variety for a particular agricultural zone should include adequate plant height and heading/flowering time that are influenced by multiple genes and can be efficiently developed based on the chromosome engineering and application of molecular markers [40,41,42]. Ddw1 can be recommended as a major factor to decrease plant height in the spring triticale.…”

Triticale is a relatively new crop which still possesses serious drawbacks that can be significantly improved by breeding. The dwarfing genes proved to be very useful in the development of new lodging resistant and productive cultivars of winter triticale. The aim of our research was to assess the effect of the Ddw1 dwarfing gene from rye on the agronomic valuable traits in spring triticale. The Ddw1 effect was studied in the greenhouse experiment in segregating the F2:3 population and in the field of F3:4 and F4:5 families derived from crossing winter triticale ‘Hongor’ (Ddw1Ddw1) and spring triticale ‘Dublet’ (ddw1ddw1). As a result, in all three generations, a strong decrease in plant height was demonstrated that was accompanied by a decrease in grain weight per spike and 1000-grain weight. In field experiments, a decrease in spike length and increase in spike density and delay in flowering and heading were observed. As a result of decrease in culm vegetative weight due to Ddw1, the harvest index measured in F4:5 increased. The spike fertility and number of grains were not affected by Ddw1. The comparison of Ddw1 in rye, winter, and spring triticale, and the possible role of Ddw1 in improving spring triticale are discussed.

“…This variety isolated from Poland and shows a stable manifestation over two years of higher yields, the number of spikelets and grain weight. The second main group contains most of selection genotypes of RSAU -MTAA and is probably caused by selection of forms, includes 2R/2D or other substitution (Divashuk et al, 2010). This group was divided into two subgroups the first subgroup IIA included the two line triticale genotypes 6-35-5 and PL-13-5-13.…”

Twenty genotypes triticale were evaluated in an alpha lattice design and RCBD for eight characters to a comparison of the relative efficiency (RE) of alpha-lattice design and RCBD. Two experiments were analyzed according to alpha lattice design and RCB design. Average estimated (RE) was 12.97, 5.93, 21.79, 35.50, 21.53, 23.96 and 26.69% for number of plants / m2, tillering fertility, plant height (cm), spike length (cm), number of spikelets / spike, 1000-grain weight (g) and grain yield (g / m2), respectively, the high precision is obtained significantly to estimate treatment effects indicating that using an alpha lattice design in place of RCBD. Mean comparisons for both RCBD and alpha lattice design were performed and two designs confirmed to Dublet, Ulyana, 131/1656 and C259 genotypes were the highest yield (g / m2). Cluster analysis showed that genotypes were isolated into three principle groups and one of these contains one variety (Dublet). This variety was characterized by a high yield over two years. The results showed that alpha lattice more efficient and it can be used it instead of traditional RCB design in the agricultural field trials.

“…According to the research consistent increase in the yield of cultivated varieties is based on the improvement of their cultivation technologies and the achievements of breeding [4]. Using of molecular methods in the breeding process is particularly relevant at the present, which is confirmed by a long list of scientific publications on the study of genetic variability of oats [5][6], triticale [7][8][9][10][11][12] and wheat [12][13][14].…”

During the research, 15 genotypes of grain crop (4 spiecies of Hordeum and 11 of Triticum) from the genbank collection of the Scientific Center of Agrobiotechnology were studied. The gluten locus of all studied cultivated and wild species is polymorphic consisting of GluA, GluB, GluC, GluD, GluE alleles. Moreover, GluB, GluC and GluD alleles have the highest meeting frequency, it is 82.35%. The GluE allele has the lowest frequency of occurrence at 41.17%. The following genotypes were formed in the gluten locus: GluAA, AB, BB, BC, CC, CD, DE, EE, EF, the frequency of which is equal to 47.05, 29.53, 70.58, 82.35, 76.47, 17.65, 52.94, 35.29, 23.53 and 23.53%. The highest frequency was recorded for GluBC genotype (82.35%), and the lowest for GluAB, EE, EF (25.53%) genotypes. In the studied species of wild barley, homozygosity is 60-100%, in the case of wild wheat - 66.7-71.42%. Indicators are close to the genetic makeup of free-breeding populations. It ranges from 50-80% in wheat amphidiploids and 25-60% in non-amphidiploids. The genetic similarity index of wild barley species ranges from 0.488 to 0.648, which indicates a unique and rich biodiversity. Meanwhile, it is quite high (r=0.844) in wild types of wheat. For amphidiploid x wild einkorn wheat, it is 0.982-0.982. In other cases, the genetic similarity index ranges from 0.488 to 0.648.
