“…The pattern of 5R transmission differed from that of 2R. In addition to t5RS telocentrics, the 5R chromosome formed isoch romosomes i5RS and chromosomes with T5RS.5RL del deletions, whereas there were no translocated 5R/5D chromosomes (Silkova et al, 2011).…”

Transmission of the rye 2R chromosome in backcrosses of wheat-rye substitution lines 2R(2D) 1 , 2R(2D) 2 , and2R(2D) 3 (Triticum aestivum L. cv. Saratovskaya 29 / Secale cereale L. cv. Onokhoiskaya, 2n = 42) to common wheat varieties Saratovskaya 29 (S29), Novosibirskaya 67 (N67), and line Lutescens 307/97 23 (Lut307) has been studied. Rye chromosomes are present in the progeny of hybridsLut307 × 2R(2D) 1 in the disomic or monosomic states; telocentrics and 2R/2D translocations have been recorded as well. The frequency and mode of 2R chromosome transmission are influenced by the gen otypes of both the wheat-rye substitution line and the recurrent variety. In the backcrossing to N67, rye chro mosomes of lines 2R(2D) 1 and 2R(2D) 3 replace the 2D chromosome more often than in crosses to Lut307 or S29. Chromosomes with aberrations were found in 26% of the hybrids after the first backcross. In the recip rocal cross of 2R(2D) 1 to Lut307, the 2R chromosome was found only in two plants. Putative mechanisms that are responsible for translocations between homological chromosomes of wheat and rye are considered.

“…Studies were conducted to investigate the transmission of rye (Secale cereale L.) chromosome 5R through gametes of dimonosomic 5R5D (2n = 42, 20W'' + 5R'+ 5D'). Cytological and molecular genetic analysis revealed the low competi tiveness of chromosome 5R as compared to 5D [8].…”

“…Therefore, intense studies are conducted all over the world to ensure adequate wheat immune defenses and to develop anticipatory protective systems. These studies include the search for new resistance genes among wild and cultivated relatives and their introgression into the wheat genome to develop highly immune forms [7][8][9].…”

Recent advances in genetics and genetic research methods made it possible to explain the large polymorphism observed among storage proteins of wheat grain (gliadins and glutenins), to determine their genetic control mechanism, and to develop a system for the identification of wheat genotypes on the basis of multiple allelism. This system has extremely high sensitivity and efficiency, which makes it possible to con duct studies to determine the purity and authenticity of wheat cultivars, the dynamics of alleles diversity in time and space, the phylogenetics, etc., through the use of an extensive database on the allelic composition of gliadin loci. An investigation of the molecular structure of genes controlling the synthesis of storage pro teins and their organization on chromosomes, as well as an analysis of wheat genome structure, revealed the molecular mechanisms of variability in the wheat genome and its reorganization in response to changes in environmental conditions and cultivation technologies. The multilevel genetic system of protection against pathogens and adverse environmental factors that developed in the course of wheat evolution continues to astound researchers' imagination with new resistance genes and novel types of antimicrobial peptides having been discovered and sequenced in recent years and the diversity of their structures and mechanisms of action in response to pathogens. An analysis of nucleotide sequences involved in wheat domestication, namely, those that define ecological plasticity, i. e. the type of plant development (Vrn genes), and those responsible for spikelet traits (Q genes), which ensured the successful cultivation of wheat by humans, revealed that the basis for these features are specific mutations.

Sylvarum published by Francis Bacon. In 1859-65, German botanists made developments in the techniques of soil-less culture. In 1929, solution culture was promoted by William Frederick Gerick for agricultural crop production. The word "Hydroponic" was firstly introduced by the William Frederick Gerick in 1937. In 1946, English scientist W.J. Shalto Duglas introduced the Hydroponics in West Bengal India. Nutrient film technique was developed by by English scientist Allen Cooper in 1960.
