Marker-assisted selection efficiency in populations of finite size.
The efficiency of marker-assisted selection (MAS) based on an index incorporating both phenotypic and molecular information is evaluated with an analytical approach that takes into account the size of the experiment. We consider the case of a population derived from a cross between two homozygous lines, which is commonly used in plant breeding, and we study the relative efficiency of MAS compar...
متن کاملMolecular marker-assisted selection of the ae alleles in maize.
The ae (amylose extender) recessive mutant alleles in maize are an important genetic resource for the development of high-amylose cultivars. On the basis of ae allele sequences (from the National Center for Biotechnology Information), the ae mutant alleles were cloned from high-amylose maize and the allelic Ae gene from common maize luyuan92 inbred lines. Five pairs of primers were designed to ...

انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
15 صفحه اولSNP Marker Assisted Selection for Identification of Fusarium Resistant Melon Plants
Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...
متن کاملThe accuracy of marker-assisted selection for quantitative traits within populations in linkage equilibrium.
Using the concept of conditional coancestry, given observed markers, an explicit expression of the accuracy of marker-based selection is derived in situations of linkage equilibrium between markers and quantitative trait loci (QTL), for the general case of full-sib families nested within half-sib families. Such a selection scheme is rather inaccurate for moderate values of family sizes and QTL ...
