A wide array of molecular markers has been used to investigate the genetic diversity among common bean species. However, the best combination of markers for studying such diversity among common bean cultivars has yet to be determined. Few reports have examined the genetic diversity of the carioca bean, commercially one of the most important common beans in Brazil. In this study, we examined the...

Backcrosses of rainbow trout and steelhead (Oncorhynchus mykiss) were used to construct a linkage map and to identify associations between molecular markers and quantitative trait loci (QTL) determining resistance to infectious hematopoietic necrosis virus (IHNV). The sire map covers 1019 centimorgans (cM), and it is composed of 257 molecular markers [185 amplified fragment length polymorphisms...

the applicability of rapds, aflps, and ssrs to examine genetic relationships in 36 populations of triticum boeoticum from west of iran was investigated. a total of 224 (135 polymorphic), 979 (429 polymorphic) and 246 (145 polymorphic) bands/alleles were detected using 14 rapd primers, 17 aflp primer combinations and 17 well distributed, mapped ssr markers, respectively. the polymorphic informat...

Amplified fragment length polymorphisms (AFLPs) currently are among the most widely used marker systems. In many studies, AFLPs are analyzed on the basis of the presence or absence of a band on an electrophoretic gel. As a result, dominant homozygous individuals are not distinguished from heterozygous individuals, resulting in a considerable loss of information. This article shows how codominan...

Amplified fragment length polymorphisms are a PCR-based genetic tool used to mark the presence or absence of alleles in a DNA sample. This tool has typically been used for genetic analysis in plants, but research is now being done to see if it is a reliable source for paternity analysis in animals. Samples of Orconectes limosus were collected from Quinebaug River during a previous study and mat...

Based on ideas from plant breeding and the opportunities offered by molecular biology, a program was initiated in 1995 to derive genetically superior tilapia from a synthetic stock Ž . artificial center of origin, ACO produced by inter-crossing five groups of fish: Oreochromis w Ž . Ž . x Ž . Ž . niloticus wild-type On and red ROn strains , O. aureus Oa , O. mossambicus Om , and Ž . Ž . Ž . Sar...

The swallowtail butterfly, Papilio dardanus, is an iconic example of a polymorphic Batesian mimic. The expression of various female-limited colour forms is thought to be controlled by a single autosomal locus, termed H, whose function in determining the wing pattern remains elusive. As a step towards the physical mapping of H, we established a set of 272 polymorphic amplified fragment length po...

Amplified Fragment Length Polymorphism (AFLP) was used to establish the genetic relationships among 20 species from seven of the nine sections of genus Arachis. The level of polymorphism among nine accessions of the cultivated peanut, A. hypogaea L., was also evaluated. Three combinations of primers were used to amplify the AFLPs. The fragments were separated in 6% denaturing acrylamide gels. A...

A genetic linkage mapping study was conducted in 93 doubled-haploid lines derived from a cross between Triticum aestivum L. em. Thell 'Arina' and a Norwegian spring wheat breeding line, NK93604, using diversity arrays technology (DArT), amplified fragment length polymorphism (AFLP), and simple sequence repeat (SSR) markers. The objective of this study was to understand the distribution, redunda...
