Comparison of RAPD Marker Patterns

An analysis of morphological, physiological, and molecular data from five cactus fruit varieties from Mexico and Chile, two ornamental Texas accessions, and one vegetable accession from Mexico are presented. Molecular analysis was performed using the RAPD (random amplification of polymorphic DNA) method. Phenotypic and molecular analyses distinguished ornamental, vegetative, and fruit market ac...

Sex ratio variation among gynodioecious populations of sea beet: can it be explained by negative frequency-dependent selection?

This study is devoted to assess sex ratio variation among 33 populations of the gynodioecious Beta vulgaris ssp. maritima in Brittany (France) and to explore the causes of this variation. We showed that three different CMS (cytoplasmic male sterility) cytotypes occurred in populations, but strongly differed for their frequencies and the frequency of their associated nuclear restorer alleles (wh...

Predicting rates of inbreeding in populations undergoing selection.

Tractable forms of predicting rates of inbreeding (DeltaF) in selected populations with general indices, nonrandom mating, and overlapping generations were developed, with the principal results assuming a period of equilibrium in the selection process. An existing theorem concerning the relationship between squared long-term genetic contributions and rates of inbreeding was extended to nonrando...

Marker aided selection for aroma in F2 populations of rice

Marker aided selection (MAS) can be used for monitoring the presence or absence of genes in breeding populations and can be combined with conventional breeding approaches. In this study, crosses between two high yielding cultivars, Neda and Nemat with local aromatic varieties Sang tarom and Tarom deylamani were made followed by phenotypic selection for desirable individual plants in F2 populati...

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...
