genetic diversity of genotypes of durum wheat (triticum turgidum l.) genotypes based on cluster and principal component analyses
نویسندگان
چکیده
genetic diversity is the basis of the natural evolution of plant breeding and biological system are important components of sustainability. the aim of this study was to evaluate 116 genotypes of triticum turgidum from seven countries in terms of morphological traits. the results showed that high significant differences among the genotypes. the correlation between grain yield and weight per spike was significant and positive, while the correlation between days to heading, length of peduncle and plant height was significant and negative. the factor analysis classified four main groups which accounted for 74.4% of the total variability. the results indicated the presence of high genetic diversity among the genotypes. the tested genotypes were classified in three groups according to the linkage distance analysis. our findings suggest that the parents from divergent clusters can be used for hybridization to isolate useful recombinants in the segregating generations, the genetics and breeding programs for improvement of durum wheat.

Effect of drought stress on MYB gene expression and osmotic regulator levels of five durum wheat genotypes (Triticum turgidum L.)
Plant growth is greatly influenced by environmental stresses including water deficit, salinity and extreme temperatures. Therefore, the identification of genes, especially regulatory ones whose expression enables plants to adapt to or to tolerate these abiotic stresses, is very essential. MYB proteins, a superfamily of transcription factors, play regulatory roles in developmental processes and ...
متن کاملGenetic Diversity of Bread Wheat (Triticum aestivum L.) Genotypes Using RAPD and ISSR Molecular Markers
The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the g...

In the present study, 150 accessions of worldwide originated durum wheat germplasm (Triticum turgidum spp. durum) were observed for major seedling traits and their growth. The accessions were evaluated for major seedling traits under controlled conditions of hydroponics at the 13th, 20th, 27th and 34th day-after germination. Biomass traits were measured at the 34th day-after germination. Correl...
