“…Very weak correlations between morphologic and molecular data were also reported by Cupic et al (2009). No correlations between phenotypic and molecular data were found Petrovic et al (2017), implying that both types of data should be used for genetic diversity estimates in order to cover wider variability between tested cultivars.…”

The genetic diversity estimates can be useful in important genotypes selection for plant breeders. Eight durum and three bread wheat cultivars were used to study and compare morphological traits with molecular study using SSR technique based genetic diversity estimates. Significant and highly significant differences among wheat genotypes were observed for all traits except flag leaf attitude and outer glume pubescence. Highly significant differences were obtained between durum and bread wheat genotypes for most studied traits. Moderate to low broad-sense heritability estimates were obtained for morphological studied traits. Positive and high significant correlation was found for ear density with foliage color (r= 0.51), waxiness of flag leaf sheath (r= 0.57), waxiness of peduncle (r= 0.60) and peduncle length (r= 0.53), whereas a negative correlation was found between ear density and plant height (r=-0.52, P<0.01). However, waxiness of flag leaf sheath was positively correlated with ear waxiness (r= 0.53, P<0.01), waxiness of peduncle (r= 0.56, P<0.01), and Peduncle length (r= 0.43, P<0.05). The higher polymorphism (90.63%) was found in the B genome than in the A genome (81.97%). Single marker analysis showed that 11 SSR markers were significantly associated with phenotypic traits, including Xgwm111-2B associated with waxiness of peduncle. A significant but low correlation (r = 0.25) was found between the dissimilarity matrix generated from the phenotypic data and that obtained from the SSR markers, suggesting that the characterization based on agromorphological traits and SSR markers will be a useful tool to the breeders for selection of genotypes with appropriate.

“…Since the development of biotechnologies, molecular marker techniques, such as AFLP, SSR and SNP, have been widely used in the analysis of genetic diversity in common wheat (CHAO et al, 2010;PETROVIC et al, 2017). But all of them have various degrees of limitations (AKBARI et al, 2006).…”

Population structure of Chinese southwest wheat germplasms resistant to stripe rust and powdery mildew using the DArT-seq technique

Understanding genetic variability in existing wheat accessions is critical for collection, conservation and use of wheat germplasms. In this study, 138 Chinese southwest wheat accessions were investigated by genotyping using two resistance gene makers (Pm21 and Yr26) and DArT-seq technique. Finally, about 50% cultivars (lines) amplified the specific allele for the Yr26 gene (Gwm11) and 40.6% for the Pm21 gene (SCAR1265). By DArT-seq analysis, 30,485 markers (6486 SNPs and 23999 DArTs) were obtained with mean polymorphic information content (PIC) value 0.33 and 0.28 for DArT and SNP marker, respectively. The mean Dice genetic similarity coefficient (GS) was 0.72. Two consistent groups of wheat varieties were identified using principal coordinate analysis (PCoA) at the level of both the chromosome 6AS and the whole-genome, respectively. Group I was composed of non-6VS/6AL translocation lines of different origins, while Group II was composed of 6VS/6AL translocation (T6VS/6AL) lines, most of which carried the Yr26 and Pm21 genes and originated from Guizhou. Besides, a model-based population structure analysis revealed extensive admixture and further divided these wheat accessions into six subgroups (SG1, SG2, SG3, SG4, SG5 and SG6), based on their origin, pedigree or disease resistance. This information is useful for wheat breeding in southwestern China and association mapping for disease resistance using these wheat germplasms in future.

“…Both genotypes included in this research are Croatian genotypes, released in the year 1989 (Srpanjka) and 2006 (Renata). There are some similarities between genotypes in agronomic traits due to the genotype Renata pedigree (Srpanjka was one of Renata’s parents) [ 35 ]. Although these genotypes differ in quality traits [ 36 ], they are similar in grain yield (as confirmed by this study) ( Table 3 ) and plant height, two traits that are very often related to the mineral content of grain.…”

The grain yield and concentrations of Fe, Zn, Se, Cd, and P in two winter wheat genotypes and in vitro bioaccessibility of Fe and Zn under the effect of different nitrogen fertilization and Zn-Se foliar application were evaluated. The total grain Fe, Zn, and Se concentrations, as well as Fe and Zn concentrations, after in vitro digestion were under the strongest effect of foliar Zn-Se application. On the other hand, Fe and Zn bioaccessibility (%) were under the most substantial effect of genotype. Regarding the need to increase concentrations of essential micronutrients in wheat grain, foliar Zn-Se application is a reliable and accepted agricultural practice, but to improve mineral bioaccessibility in human nutrition, foliar Zn-Se application should be combined with the most responsive genotypes. For this reason, further research on the genotype specificity of wheat regarding micronutrient bioaccessibility should be carried out.
