This article presents the results of determining the attracting ability of the whole box and the degree of its differences depending on the genotypes, as well as its prospects for solving practical problems of selection of medium-fiber cotton. Consequently, among the genotypes studied by us, a significant amount of the attractive ability of a single box, the value of attraction and the mass of raw cotton per box differed in 10 combinations, which are economically the most productive.

Cotton (Gossypium hirsutum L) is considered as major textile fiber around the world. This research aimed to analyze the molecular diversity among 9 cotton genotypes collected from Cotton Development Board, Bangladesh using the 7 Random Amplified Polymorphic DNA (RAPD) markers. Some total of 18 DNA bands were obtained and among them, 13 were polymorphic bands. The range of DNA amplification varied from 180 to 800 bp. The percentage of polymorphism was about 50.71. Genetic diversity ranged from 0.22 to 0.44 with an average value of 0.34. Nei’s genetic distance ranging from 0.1667 to 0.6667 and most importantly PIC value ranged from 0.18 to 0.35 with an average value of 0.27. The PIC value indicated that most of the studied cotton genotypes were moderately diversified and homogenous as well as no heterozygosity found. A dendrogram indicating the relative genetic similarity of the Bangladeshi cotton genotypes was constructed which followed in two major clusters (A and B) among the studied material. The Cotton Development Board (CDB), Bangladesh committed to working on cotton improvement and this investigation will be helpful for the selection of diversified genotypes in varietal improvement in cotton. The output of this research will be a baseline for future molecular research work on cotton genotypes in Bangladesh.

DNA fingerprinting is rapid, easy, and efficient method for discrimination, identification and characterization of various genotypes for protection of plant breeder’s rights (PBRs). Present study was designed for DNA fingerprinting and genetic diversity assessment of 25 GM cotton genotypes (possessing Cry1Ac gene) using 297 SSR markers through conventional PCR and Polyacrylamide gel electrophoresis. Out of 297 SSR markers, 25 markers were not amplified, 28 were monomorphic and 244 were polymorphic. A total of 1537 alleles were amplified among which 1294 (84.18%) were polymorphic. PIC value in our study ranged from 0.08 to 0.93 with an average of 0.73. Unique allelic pattern was observed for nineteen genotypes whereas six genotypes were identified using two-step identification methods. The UPGMA dendrogram divided the genotypes into two distinct clusters. Cluster I was comprised of 20 genotypes whereas cluster II was comprised of four genotypes. MNH-1020 did not obey any clustering and remained separated. The results of the structure analysis were complementary to cluster analysis and the population was divided into two subgroups. Our results evidenced narrow genetic base of the cotton genotypes cultivated in Punjab Pakistan due to use of common parents in the pedigree/parentage. Further, we proposed a core set of markers for future DNA fingerprinting and genetic diversity studies. The information generated in this study will be helpful in variety registration and subsequent protection under PBRs. Further our findings will be useful in selection of SSR markers for future studies which are focused on DNA fingerprinting and genetic diversity assessment. © 2021 Friends Science Publishers

The most important factor in the intensification and rise of the production of the cotton industry in Tajikistan is the selection of new varieties characterized by high yield and its quality. The increase in the production of the cotton industry can be achieved not by expansion of acreage, since this possibility is very limited in a mountainous country, but by breeding new varieties of cotton and spreading them into production. The use of photosynthetic test characteristics in breeding contributes to the process of creating new varieties that meet the demand of agricultural production and the textile industry, i.e. varieties with a complex of economically useful features — precocity, high productivity, resistance to diseases and pests, optimal adaptive properties, characterized by high fiber yield and its technological quality. By methods of hybridization and selection by offspring on the basis of photosynthetic test characteristics from domestic and foreign variety samples, 28 introgressive genotypes were created that are characterized by complex of economically useful traits. It was found that out of the 28 genotypes of medium-fiber cotton studied by us, according to the main indicators of productivity — the number of full-fledged boxes per plant, the mass of raw cotton of one box and the yield — 6 genotypes were notable. The number of boxes per plant in the most productive was 12–15 pieces, the mass of raw cotton of one box is up to 6.6 g, and the yield of raw cotton is from 71.5 to 93.0 g/plant, which is significantly higher than in the standard Hisor variety.

Abstract Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.
