having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...

Random amplified polymorphic DNA (RAPD) analysis was employed to estimate genetic diversity/genetic similarity among nine wheat (Triticum aestivum L.) genotypes. Out of 25 random 10-mer primers surveyed, 18 primers detected polymorphism among all the wheat genotypes, while 7 primers produced monomorphic pattern. A total of 175 bands were amplified, 60.57% of which were polymorphic. Genetic simi...

tall fescue (lolium arundinaceum (schreb) sj darbysh.) is one of the fescue species that widely used as forage grass. tall fescue is self-incompatible and wind cross pollination. this study was conducted to study agronomic and morphological characteristics of 25 polycross families of tall fescue during 2011 and 2012 at research station farm in isfahan. number of days to pollination, height of p...

to evaluate allelic diversity at loci encoding low molecular weight glutenin subunits (lmw-gs) among 62 genotypes of bread wheat, nine specific primer pairs for glu-a3, glu-b3, glu-d3 loci were employed. pcr products were separated on 2% agarose gels. two pairs of specific primers, at amplified glu-a3 locus, 8 alleles were detected the c allele of which was the most abundant with a frequency of...

Microsatellites or simple sequence repeats (SSRs) are highly useful molecular markers for plant improvement. Expressed sequence tag (EST)-SSR markers have a higher rate of transferability across species than genomic SSR markers and are thus well suited for application in cross-species phylogenetic studies. Our objectives were to examine the amplification of tall fescue EST-SSR markers in 12 gra...

phytic acid is a major storage form of phosphorous in cereals that acts as food inhibitor by chelating micronutrients and prevents it to be bioavailabe for monogastric animals, including humans. ninety three wheat (triticum aestivum l.) germplasms, including cultivars from india, were characterized for phytic acid and fe contents. phytic acid contents ranged from 0.59 (iitr 92) to 2.08% (iitr 2...

wheat (triticum aestivum l.) is a major staple food crop for more than one third of the world population and is the main staple food of asia. over 800 million hectares of land throughout the world are salt affected. salinity is a major obstacle to food production because it substantially reduces the average yield of major crops. this study was conducted to evaluate the response of 24 cultivars ...
