in this research, allele frequency and polymorphism of 27 microsatellite markers linked to gene loci controlling grain quality were determined between 47 rice varieties from four different groups including 21 iranian local, 16 improved, 7 irri and 3 upland rice varieties. average number of polymorphic information content (pic) and shannon’s diversity index were 0.54 and 1.14, respectively. maxi...

In this paper, the varying-coefficient single-indexmodel (VCSIM) is proposed. It can be seen as a generalization of the semivaryingcoefficient model by changing its constant coefficient part to a nonparametric component, or a generalization of the partially linear single-indexmodel by replacing the constant coefficients of its linear part with varying coefficients. Based on the local linear met...

selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. the present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. for this purpose an experiment was c...

iris belongs toiridaceae family and it is monocotyledon. iris is one of the important ornamental and medicinal plants. 34 iris genotypes (14 species) collected from different provinces of iran were planted at national institute of ornamental plants (niop) iran. all of the species evaluated for 15 quantitative traits and 30 qualitative traits. results showed that the highest positive correlation...

Spatial variability in species richness has been postulated to depend upon environmental factors such as climatic variability, Net primary productivity and habitat heterogeneity. The Advanced Very High Resolution Radiometer (AVHRR)-Normalized Difference Vegetation Index (NDVI) has been shown to be correlated with climatic variability, Net primary productivity and habitat heterogeneity. Moreover...

this study was performed  in second half of year 2009.for bird counting , monthly from septamber until march 2009. total counted birds in maroon lake were (971). maximum number of counted birds was in february  (191) and minimum of counted was in septamber (95). total counted birds in jaizan were (385. maximum number of the counted bird was in february (84) and minimum of counted (52) was in ja...
