Background: GeneXpert MTB/RIF is a real-time PCR assay with established diagnostic performance in pulmonary and extra-pulmonaryforms of tuberculosis. The aim of this study was to assess the contribution of GeneXpert MTB/RIF assay to the management ofpatients with any form of active tuberculosis in a single large tertiary center in Saudi Arabia, with a special focus on the impact ontime to start of antituberculous therapy compared with Ziehl-Neelsen (ZN) smears and mycobacterial cultures. Materials and Methods: Clinical, radiological and laboratory records for all patients who were commenced on antituberculous therapybetween March 2011 and February 2013 were retrospectively reviewed. Results: A total of 140 patients were included, 38.6% of which had pulmonary tuberculosis. GeneXpert MTB/RIF was requested for only39.2% of patients and was the only reason for starting antituberculous therapy for only 12.1%. The median time to a positive GeneXpertMTB/RIF result was 0 days (IQR 3) compared with 0 day (IQR 1) for smear microscopy (P > 0.999) and 22 days (IQR 21) for mycobacterialcultures (P < 0.001). No patients discontinued antituberculous therapy because of a negative GeneXpert MTB/RIF result. Conclusions: In a setting wherein physicians are highly experienced in the diagnosis and treatment of tuberculosis, GeneXpertMTB/RIF was remarkably under-utilized and had only a limited impact on decisions related to starting or stopping antituberculoustherapy. Cost-effectiveness and clinical utility of routine testing of all smear-negative clinical samples submitted for tuberculosisinvestigations by GeneXpert MTB/RIF warrant further study.

Genotype × environment interaction is one of the complex issues of breeding programs to produce high-yielding and compatible cultivars. Interaction of genotype × environment and make the more accurate selection, the performance and stability of hybrids need to be considered simultaneously. This study aimed to investigate stable genotypes with yield using 12 maize hybrids in different climatic conditions of Iran. The experimental design used was a randomized complete blocks design in three replications in two cropping years in Karaj, Birjand, Shiraz, and Arak stations. The simple analysis of variance performed on grain yield of genotypes indicated that all hybrids studied each year and station were significantly different in grain yield. Also, the combined analysis results showed a significant effect on the environment, the effects of genotype, and the interaction of genotype × environment and t in the studied hybrids different. Comparing Duncan's mean on the data obtained from the research, KSC705 genotypes with an average yield of 7.21 and KSC704 genotype with an average yield of 7.04 were identified as high yield cultivars. In order to identify stable cultivars, six stability parameters were used. KSC260 and KSC707 genotypes had stability Based on the environmental variance, also had stability based KSC705, KSC707 genotype on environmental the coefficient of variation, and KSC260 genotypes had stability based methods of genotype and environment interaction. As well as based on Eberhart and Russell regression coefficient had the stability to KSC400 and SC647 genotypes. Also, they were identified as the most stable genotypes based on the detection coefficient method, KSC707, and KSC703 genotypes.
