چکیده: 

The objective of this investigation was to evaluate the magnitude of G×E interaction effects on durum wheat grain yield and to identify superior genotypes adapted to the test environments. Twenty improved durum wheat genotypes were tested in five locations over three growing seasons. Combined ANOVA indicated that the effect of year (Y) was significant and that of the location (L) was not, but that their interaction (Y×L) was highly significant. The main effect of genotype was also significant, as was the genotype×year interaction (G×Y), genotype×location interaction (GL) was not significant, but three-way interactions (G×Y×L) were highly significant. Clustering of genotypes based on intercept and slope parameters of the linear regression model produced three distinct groups, while using only line slopes for clustering produced no groups at all. The coefficient of determination of the linear regression model ranged from 0.84 (G10) to 0.98 (G2), therefore, it can be concluded that this clustering method was somewhat useful for this data set. According to the dendrogram of clustering based on G and G×E interaction of ANOVA, there were 15 genotypic groups, while according to the dendrogram of clustering based on G×E interaction of ANOVA, there were 12 genotypic groups. Considering all clustering methods and mean grain yield, genotypes G8 (2590 kg ha-1) and G13 (2592 kg ha-1) were superior and thus can be recommended as candidates for release in warm rainfed areas of Iran.

چکیده: 

Based on principal component analysis (PCA), GGE biplot analysis is an effective method to fully assess multi-environmental yield trials (METs). Additive main effects and multiplicative interaction (AMMI) is an alternative method for assessing phenotypic stability and adaptability. In this research, MET data of 14 maize inbred lines were used to perform AMMI and GGE biplot analyses. These genotypes were evaluated under diverse climatic conditions in five Iranian locations during two cropping cycles (2007 and 2008). A genotype (inbred line) by location table was used for performing the analyses. Based on both mean grain yield and yield stability, inbred lines K3615/2, K19/1, K166B and K18 proved to be superior and also had greater mean performance among the test inbred lines. Graphic analysis was used to identify the most suitable inbred lines for each test environment. Inbred lines K3615/2, K19/1, K166B, K18, K3653/2 and K3547/5 were identified as suitable in all locations. The AMMI and GGE biplot graphics revealed three separate groups of environments, i.e., three mega-environments. Group one included three sites, Karaj, Kabootar Abad and Zarghan, while group two included only Islam Abad-e-Gharb and group three only Miandoab. Islam Abad Gharb and Miandoab were more discriminative for genotypes. The inbred lines that were most responsive to the environment were K3615/2, K166B, K19/1 and K18; the least responsive line was K3547/5.

چکیده: 

Stable performance of new improved bread wheat (Triticum aestivum L.) genotypes in multi-environment trials is important in crop improvement programs. In such trials, genotype evaluation and mega-environment identification are the most important objectives. The yield stability of 18 bread wheat genotypes was investigated through genotype (G) and genotype × environment (GE) interaction using the GGE biplot technique. Field experiments were conducted in 12 warm rainfed environments in Iran to characterize G × E interactions for grain yield of bread wheat genotypes. A combined analysis of variance across locations showed that both main effects (environment and genotype) and GE interactions were highly significant. Principal component analysis was performed, and the first two principal components (PC1 and PC2) explained 45% and 26% of the total sum of squares, respectively, they were used to create GGE biplot diagrams. The polygon tool of the biplot suggested two bread wheat growing environments in warm dryland regions of Iran: a small one (Moghan) and a large one (Gachsaran, Gonbad and Khoramabad). Visualizing the mean and stability parameters of the genotypes in the biplot indicated that genotypes HAMAM-4 (G1) and CHEN/AEGILOPS SQUARROSA (TAUS)//BCN/3/VEE#7/4/PASTOR (G4) are adapted to warm rainfed areas of Iran. The vector view of the biplot showed that Gonbad, Khoramabad and Gachsaran were correlated, but had no association with Moghan. Finally, it was concluded that G1 and G4 showed high yield stability across environments and are, therefore, recommended for release in warm rainfed areas of Iran.

Background: Transforming growth factor-beta 1 (TGF-β1) T869C (rs1800470, the same below) gene polymorphism is notably relative with the development of Diabetic Nephropathy (DN) ,and CC/CT genotype diabetic have higher frequency of than TT genotype diabetic. To find out individual risk factors in the two genotypes especially in suscepti-ble genotype could provide more efficient and targeted prevention.Methods: This was a prospective cohort study. A total of 251 type 2 diabetes mellitus (T2DM) patients [53.4% male, 56 (52-67) years] were enrolled in this cohort study. Multiple concerned factors were collected and the relationship of these risk factors and development of DN were evaluated by Cox regression analysis. Hazard ratios of development of DN were calculated by Kaplan-Meier curves and the Cox proportional hazards model for CC/CT genotype versus TT genotype patients.Results: TGF-β T869C gene polymorphism was an independent predictor of DN in T2DM patients (HR, 2.08; 95%CI, 1.18-3.66; P=0.012). Hyperlipemia (HR, 1.91; 95%CI, 1.19-3.08; P=0.007), age (HR, 0.95; 95%CI, 0.93-0.98; P=0.001) and smoking status (HR, 2.36; 95%CI, 1.07-5.21; P=0.033) were risk indictors of the development of DN in CC/CT genotype patients. HbA1c (HR, 2.8; 95%CI, 1.07-7.30; P=0.036), hypertension (HR, 7.46; 95%CI, 1.38-40.29; P=0.02), and hyperlipemia (HR, 12.33; 95%CI, 1.05-145.39; P=0.046) were risk indictors for the development of DN in TT genotype patients.Conclusion: TGF-β T869C gene polymorphism was an independent predictor of DN for T2DM patients and CC/CT genotype had higher susceptibility to DN. CC/CT genotype and TT genotype patients had different risk in-dictors of DN.

چکیده: 

Asymptomatic hepatitis B infection is characterized as a type of hepatitis in which hepatitis B surface antigen is present in the patient’s peripheral blood despite the absence of clinical symptoms. Previous studies have shown that a particular genotype may affect clinical manifestations of hepatitis B infection; hence, the aim of the current study was to determine the frequency of hepatitis B virus genotypes among asymptomatic carriers of hepatitis B. In this experimental study, the plasma samples of 100 asymptomatic carriers were collected and tested for HBsAg and anti-HBs using ELISA. The genotype of hepatitis B virus was determined by the GAP-PCR technique.The results of this study showed that all samples were positive for hepatitis B surface antigen and anti-hepatitis B core antigen was present in 60 (60%) cases. Our results also indicated that all patients had the D genotype of hepatitis B virus.
