Outcrossing in Southernpea1

HortScience, 1980
Abstract The average frequency of observable outcrossing among 6 genotypes of southernpea ( Vigna unguiculata (L.) Walp.) in a population of 9,987 plants was 0.59% and varied from 1.42% in AU 70.4 to 0% in Ala. 963.8G1-4. Outcrossing as high as 4.26% was recorded in a single

Rate of crop‐weed hybridization in Sorghum bicolor × Sorghum halepense is influenced by genetic background, pollen load, and the environment

Evolutionary Applications, 2023
The potential for gene flow between cultivated species and their weedy relatives poses agronomic and environmental concerns, particularly when there are opportunities for the transfer of adaptive or agronomic traits such as herbicide resistance into the ...

Outcrossing in Peach

HortScience, 1989
Abstract Malate dehydrogenase (MDH) isozyme variability in peach [ Prunus persica (L.) Batsch.] cultivars allowed estimation of outcrossing. After correction for undetectable pollen (of the same genotype as the homozygous Mdh-aa female

Effects of population outcrossing on rotifer fitness [PDF]

BMC Evolutionary Biology, 2010
Outcrossing between populations can exert either positive or negative effects on offspring fitness. Cyclically parthenogenetic rotifers, like other continental zooplankters, show high genetic differentiation despite their high potential for passive dispersal.

Conspecific crop-weed introgression influences evolution of weedy rice (Oryza sativa f. spontanea) across a geographical range.

PLoS ONE, 2011
BackgroundIntrogression plays an important role in evolution of plant species via its influences on genetic diversity and differentiation. Outcrossing determines the level of introgression but little is known about the relationships of outcrossing rates,

Hybridization of Saccharomyces cerevisiae Sourdough Strains with Cryotolerant Saccharomyces bayanus NBRC1948 as a Strategy to Increase Diversity of Strains Available for Lager Beer Fermentation

Microorganisms, 2021
The search for novel brewing strains from non-brewing environments represents an emerging trend to increase genetic and phenotypic diversities in brewing yeast culture collections.

Capturing Genetic Diversity in Seed Collections: An Empirical Study of Two Congeners with Contrasting Mating Systems

Plants, 2023
Plant mating systems shape patterns of genetic diversity and impact the long-term success of populations. As such, they are relevant to the design of seed collections aiming to maximise genetic diversity (e.g., germplasm conservation, ecological ...
