background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

BACKGROUND Nitrogen [N] is a critical limiting nutrient for plants and has to be exogenously supplied to many crops, to achieve high yield with significant economic and environmental costs, specifically for rice. Development of low-input nitrogen sustainable crop is necessary for sustainable agriculture. Identification of regulatory elements associated with low-N tolerance is imperative for for...

this study was carried out in order to evaluate allelic diversity of microsatellite markers in qtl region for salinity tolerance on chromosome 10 in rice and evaluation of agronomical traits of some iranian rice cultivars in salinity stress along with two tolerant (pokkali) and sensitive (ir29) check varieties, and association analysis for morphological traits using microsatellite markers.based...

BACKGROUND The present study was performed to identify the association of PON1 rs662 polymorphism with serum lipid levels and human longevity in the Bama Zhuang population. MATERIAL AND METHODS PON1 genotypes were determined by Taqman SNP Genotyping Assays in 110 long-lived inhabitants (longevity group, aged 90-110 years), 110 healthy inhabitants in Bama County (control 1 group, aged 43-82 year...

The identification of genomic loci involved in control of quantitative traits receives growing attention in plant molecular breeding. The present study was carried out to evaluate the genetic variability among 48 rice genotypes and determine the genomic regions associated with ten grain related important traits. A total number of 63 alleles were detected by 18 selected SSR markers from differen...

background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought  stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...

One hundred forty one basmati rice genotypes collected from different geographic regions of North Western Himalayas were characterized using 40 traits linked microsatellite markers. Number of alleles detected by the abovementioned primers were 112 with a maximum and minimum frequency of 5 and 2 alleles, respectively. The maximum and minimum polymorphic information content values were found to b...
