Genomic selection combines statistical methods with genomic data to predict genetic values for complex traits. The accuracy of prediction of genetic values in selected population has a great effect on the success of this selection method. Accuracy of genomic prediction is highly dependent on the statistical model used to estimate marker effects in reference population. Various factors such a...
This study describes the genetic relationships among 34 varieties of Lallemantia iberica using inter-retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP). Samples were collected from Agriculture Research Center of Urmia city (northwest Iran). Ten IRAP and REMAP primers generated 76 scorable electrophoretic bands with 78.94% pol...
Objective: Flowering Time (FT) in cereals controlled by genes that had a main factor on plant development. Methods: Genetic and phenotypic diversity of four flowering time genes (FT2, FT3, FT4, Ppd-H1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. Genotypes based on days to flowering time and molecular data were grouped into earl...
The validity test of the linked markers to identified QTLs is as a necessary step before performing marker assisted selection. In the present study were conducted validity test of 21 microsatellite markers associated to drought tolerance using 121 soybean varieties and advanced lines and planting in two condition normal and under drought stress at two regions Rasht and Gonbad-Kavous. In investi...

Rice as one of the most important agricultural crops has a putative potential for ensuring food security and addressing poverty in the world. In the present study, in order to provide basic information to improve rice through breeding programs, Inter Simple Sequence Repeat marker (ISSR) was used For DNA fingerprinting and finding genetic relationships among 32 different cultivars. In this study...
Large genome-wide association studies have reported hundreds of genetic markers associated with lipid levels. However, the discovery and estimated effect of variants at these loci, derived from samples of exclusively European descent, may not generalize to the majority of the world populations. We examined the collective strength of association among these loci in a diverse set of U.S. populati...
comparative assessment of genetic diversity of 122 durum wheat genotypes (triticum turgidum l. var. durum) was performed using 73 ssap polymorphic fragments, 123 aflp polymorphic loci and 104 ssr alleles. ssap and aflp data showed a clear demarcation between the cultivars and landraces and ssr data classified cultivars and landraces according to their origin. furthermore, the estimated genetic ...
Due to the importance of date palm production in Iran, introduction of new cultivars, improvement of current cultivars and studying the genetic diversity among available cultivars is essential for improvement the quantity and quality of date palm production. In this research, 15 different local genotypes of date palm collected from Saravan, Jalgh, Nahook and Sinokan regions of Sistan and Baluch...
Extended Abstract Introduction and Objective: Luffa is a plant from the Cucurbitaceae family with the scientific name of Luffa cylindrica. In addition to the food consumption of mature green fruit and the medicinal and health properties of seed oil, it is important due to the fibrous spongy texture of its dried fruits. There is a great variety in terms of shape, size, quality of sponge, etc. a...
