the aim of this study was to test the genotypes effect of dgat1 gene on breeding value in iranian holstein milk production traits. for this purpose, 103 semen samples of registered bulls were collected and then genotyped for partial region of dgat1 gene. the studied traits were milk yield (my), fat yield (fy), protein yield (py), fat percentage (fp) and protein percentage (pp). first lactation ...

Testicles were isolated from dromedary camels in a local slaughterhouse at breeding and non-breeding seasons. Sperms were recovered from different parts of the epididymis (caput, corpus and cauda) and stained separately on slide glasses by eosin nigrosin staining method and dried by a hair dryer and carried to the laboratory. In the lab, slides were observed for evaluation of the proportion of ...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

introduction: genetic resources in any country are valuable materials which needed to be conserved for a sustainable agriculture. an animal phenotype is generally affected by genetic and environmental factors. to increase mean performance in a population under consideration not only environmental conditions, but also genetic potential of the animals should be improved. although, environmental i...

in order to study dry matter accumulation in different developmental stages and photoassimilates remobilization in bread wheat genotypes, a field experiment was carried out using a split split plot design based on a randomized complete block design with three replications in torogh agricultural and natural resources research station (mashhad, iran) in 2006-2007 and 2007-2008. main plots were as...

The aim of this study was to investigate effects of DGAT1, OPN and PPARGC1A candidate genes on milk production traits in Iranian Holstein cattle. Several papers have studied single nucleotide polymorphisms (SNPs) and their association with economic traits in dairy cows, but the combined effect of these genes has not been examined in Iranian Holstein cattle population. Blood samples were collect...
