Genetic diversity between parents may contribute positively to both heterosis and transgressive segregation. The objectives of this study were to determine (i) whether genetic diversity in spring wheat (Triticum aestivum L.) affected [F.sub.2] bulk heterosis and (ii) whether genetic diversity affected the amount of transgressive segregation among progeny from a cross. Genetic diversity was measured by pedigrees, morphology, and gliadin seed proteins. Heterosis was evaluated for 137 [F.sub.2] ...

Genetic diversity and heterosis of spring wheat crosses.
Crop Science ; It has been hypothesized that an increase in genetic distance between parents will positively increase heterosis for grain yield in the resulting hybrid or [F.sub.2] bulk population. Positive associations between morphological genetic distance and heterosis have been found among crosses in winter
Heterosis in soybean and its prediciton by genetic similarity measures.
Crop Science ; Genetic diversity is an important issue in applied breeding because it is commonly assumed that the cross of diverse rather than similar parents enhances breeding success. Although genetic relations of breeding materials are never far from the mind of the breeder, quantification of diversity is
Heterosis of Biomass Production in Arabidopsis. Establishment during Early Development1
Plant Physiology ; Heterosis has been widely used in agriculture to increase yield and to broaden adaptability of hybrid varieties and is applied to an increasing number of crop species. We performed a systematic survey of the extent and degree of heterosis for dry biomass in 63 Arabidopsis accessions crossed to
Genetic distance based on simple sequence repeats and heterosis in tropical maize populations. (Crop Breeding, Genetics & Cytology).
Crop Science ; GENETIC DIVERSITY in maize plays a key role for future breeding progress. The development of molecular markers provides a tool for assessing the genetic diversity at the DNA level in plant species (Melchinger and Gumber, 1998). In particular, SSR markers show potential for large-scale DNA
Relationship between genetic distance among parents and genetic variance in populations of soybean.
Crop Science ; A goal in breeding inbred cultivars is to develop and identify high yielding transgressive segregants. This is typically done in applied breeding programs by crossing high performing lines to develop segregating populations from which new, higher performing lines are selected. Populations with
On the Choice of Genetic Distance in Spatial-Genetic Studies
Genetics ; ABSTRACT We look at how to choose genetic distance so as to maximize the power of detecting spatial structure. We answer this question through analyzing two population genetic models that allow for a spatially structured population in a continuous habitat. These models, like most that incorporate
Genetic and linguistic affinities between human populations in Eurasia and West Africa
Human Biology ; Abstract This study examines the relationship between genetic distance and linguistic affiliation for five regional sets of populations from Eurasia and West Africa. Human genetic and linguistic diversity have been proposed to be generally correlated, either through a direct link, whereby
Heterosis and inbreeding depression for forage yield and fiber concentration in smooth bromegrass.(Crop Breeding, Genetics & Cytology)
Crop Science ; VOLUNTARY INTAKE is generally considered to be the single most important factor limiting animal performance on high-forage diets (Fahey and Hussein, 1999). Physical distension of the rumen is the major factor limiting voluntary intake of high producing ruminants on high-forage diets (Mertens,
Genetic Similarity Indices for Ancestral Cotton Cultivars and their Impact on Genetic Diversity Estimates of Modern Cultivars.
Crop Science ; Maintaining genetic diversity types offers a measure of protection against potential widespread losses from crop pests and facilitates the creation of segregating populations from which plants with superior gene combinations can be selected. Accurate estimates of genetic distance may assist in crop
Pedigree and RAPD-based DNA analysis of commercial U.S. rice cultivars. (randomly amplified polymorphic DNA)
Crop Science ; Pedigree information can be used to calculate kinship coefficients (r) or coefficients of co-ancestry that estimate the probability that two alleles at a given locus are identical by decent (Malecot, 1948). An evaluation of U.S. rice germplasm showed that coefficients of co-ancestry for 141 lines
