Outcrossing in Annual Canarygrass
Crop Science, 2006Currently recommended minimum isolation distances of 3 and 10 m for pedigreed seed production of annual canarygrass (Phalaris canariensis L.; 2n = 2x = 12) may not be sufficient to maintain the purity of seed lots. The objective of this study was to estimate outcrossing (OC) rates of annual canarygrass over various distances and directions, using the ...

Crop Science, 1991
Plant breeders shape breeding and seed increase programs, in part, according to the percent outcrossing in the species. Previous reports indicated that aeschynomene, Aeschynomene americana L., was almost entirely self‐pollinated. The objective of these experiments was to determine percent outcrossing under greenhouse and field conditions.

Outcrossing and heterozygosity
Advances in Applied Probability, 1974A classical question in population genetics is ‘In a species in which there is obligate outcrossing is there an increased amount of heterozygosity?’. This somewhat vague question can have two different meanings: (1) Is the number of alleles maintained at a locus greater?

First Outcrossing Probability Bounds
Journal of Engineering Mechanics, 1984The structural reliability theory encounters the difficult problem of assessing the probability that a random vector process crosses out of a given safe domain within a given time interval. For stationary vector processes, a way of calculating an optimal lower bound is demonstrated.

Outcrossing in celery (Apium graveolens)
Euphytica, 1984Isozyme marker loci were used to measure outcrossing in artificial and natural populations of celery (Apium graveolens). In three separate experiments involving populations of uniform density and flowering time, outcrossing rate ranged from 47 to 87% and the mean was 71.4%.

Natural outcrossing in common buckwheat
Euphytica, 1998Common buckwheat is an obligate cross pollinating crop because of its sporophytic self-incompatibility system. Therefore a study to assess the extent of natural outcrossing was undertaken for two years at Morden and Portage la Prairie, Manitoba using the semi-dwarf character, which is due to a homozygous genotype with regard to a single recessive gene,

Natural Outcrossing in Rice Bean
Plant Breeding, 1987AbstractNatural outcrossing in rice bean (Vigna umbellata [Thumb.] Ohwi and Ohashi) was studied in the progenies of recessive plants in F generation of six crosses involving three loci — Ti (seed coat base colour), (seed coat mosaic) and Rr (seedling colour), The estimate of outcrossing (α) varied from 0.27 10 0.81 and the percentage of line showing ...

Evolution, 1989
The genetic consequences of a plant's mating system depend on both the degree of outcrossing and the genetic relationship between mates. We examined the electrophoretic genotypes of seeds derived from cleistogamous (CL) and chasmogamous (CH) flowers in six populations of the facultatively cleistogamous annual, Impatiens capensis.

Increased outcrossing in hothead mutants (Reply)
Nature, 2006Arising from: S. J. Lolle, J. L. Victor, J. M. Young & R. E. Pruitt Nature 434, 505–509 (2005). The results obtained by Peng . 1 are consistent with an increased amount of outcrossing in hth mutants of Arabidopsis thaliana.
