Relatedness and status number in seed orchard crops
TLDR
Properties of status number and other measures of effective number may refer to rate or state, to the reference population or the development of an idealized population, and to different moments in the sexual cycle.
Loss of genetic diversity monitored by status number
We suggest monitoring genetic diversity (= effective number) in breeding populations with a new concept status number, which is half the inverse of the average coancestry, including the coancestry of
Prediction of genetic gain and gene diversity in seed orchard crops under alternative management strategies
TLDR
Genetic gain and the gene diversity of seed crops from clonal seed orchards were formulated considering genetic selection, fertility variation and pollen contamination, and compared for five different management strategies and can be used for identifying favourable alternatives for the management of seed orChards.
Estimation of fertility variation in forest tree populations
TLDR
Books on flowering abundance, fruit and seed production and fertility variation were used to estimate and review fertility variation in 99 stands and 36 seed orchards, finding differences in fertility were usually higher during poor flowering years and in young populations.
Balancing Gain and Relatedness in Selection
TLDR
An iterative search algorithm is proposed for finding this maximum under a given breeding-population size and gave markedly better combinations of gain and average coancestry when compared with a conventional method to control relatedness by restricting contributions from individual parents.
Variation in effective number of clones in seed orchards
TLDR
The effective number of clones was estimated for 255 conifer clonal seed orchards in Finland, Korea, and Sweden, based on the variation in the number of ramets among clones, and it was found that many of these first-generation seedOrchards were established with an intention to have near-equal numbers of ramet foreach clone.
Flowering in a clone trial of Picea abies Karst
TLDR
A great variation in female as well as male flowering between the clones of Picea abies revealed and the consequences of the data obtained for the genetic composition of the seed orchard progeny were discussed.
Effects of male fecundity, interindividual distance and anisotropic pollen dispersal on mating success in a Scots pine (Pinus sylvestris) seed orchard
TLDR
A mating model that best describes the gene dispersal pattern in clonal seed orchards was constructed, and variations in pollen production explained up to 78% of the variation in mating success.
Impact of Fertility Variation on Gene Diversity and Drift in two Clonal Seed Orchards of Teak (Tectona grandis Linn. f.)
TLDR
Placing limits on how much seed can be collected per clone might be useful in restricting over representation of highly reproductive clones thereby increasing genetic diversity in the seed crop.
Can viable pollen carry Scots pine genes over long distances
TLDR
The gene flow caused by pollen migration is likely to be large enough to be of evolutionary significance in Scots pine seed crops in northern Scandinavia and has an advantage over later local pollen.
