ارزش نانوایی صفت پیچیده ای بوده و فاکتورهایی از جمله کمیت و کیفیت پروتئین گلوتن در آن دخیل است. گلوتنین های دانه گندم را می توان از نظر وزن مولکولی به دو گروه گلوتنین با وزن مولکولی بالا و گلوتنین با وزن مولکولی پایین تقسیم بندی نمود که زیر واحد سنگین تاثیر بیشتری در کیفیت نانوایی دارد. به منظور بررسی تنوع ژنتیکی ژن glu-1 (گلوتنین زیر واحد سنگین) تعداد 100 رقم گندم مورد کشت در ایران شامل ارقام ...
A primary goal in the assessment of structural variation in the avian genome is to understand the relationship of this variation with biodiversity and with biological performance. To develop such knowledge, certain essential tools are needed. One set of tools includes the laboratory techniques used to assess molecular genetic variation. The current time is a transitional one for this field, in ...
A genetic marker is a gene or DNA sequence with known localization on a chromosome. It can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. Such variations occurring at chromosomal or DNA level can serve as genetic markers. The progress in development of molecular markers suggests thei...
The combination of cytoplasmic male sterility (CMS) in one parent and a restorer gene (Rf) to restore fertility in another are indispensable for the development of hybrid varieties. To genotype rice lines at the restoring fertility (Rf) loci, 38 lines were crossed with a sterile tester (rfrf) line. Pollen fertility test was performed to identify sterile and fertile F1 hybrids. Seven lines were ...
One of the main objectives of plant breeding is defining the relationship between genotype and phenotype. Nowadays, molecular markers provide powerful tools to evaluate this relationship for plant breeders. In this study, genetic diversity of 112 rice lines was evaluated by 20 pairs of SSR markers which linked to drought tolerant alleles. Totally, 77 polymorphic alleles with mean of 3.85 allele...
