Differences in Mortality among Full-Sib Channel Catfish Families at Low Dissolved Oxygen
Progressive Fish-Culturist, 1985Abstract Fifteen full-sib channel catfish (Ictalurus punctatus) families from the Yazoo strain and eight from the Louisiana State University (LSU) strain were tested for variability in mortality rate at a low level of dissolved oxygen (1.1 ± 0.1 mg/L [ppm]).

Performance of full-sib families of Douglas-fir in pure-family and mixed-family deployments
Forest Ecology and Management, 2011Abstract A major objective of tree improvement programs is to identify genotypes that will perform well in operational deployments. Relatively little is known, however, about how the competitive environment affects performance in different types of deployments.

Late blight resistance in a diploid full‐sib potato family
Plant Breeding, 2004AbstractLate blight, caused by Phytophthora infestans (Mont.) de Bary, is the most destructive disease of potato worldwide. As this pathogen can rapidly overcome major race‐specific resistance genes, identifying the basis for enhanced quantitative resistance has become a crucial element for implementing advanced breeding strategies. A population of 230

Combined S2 and crossbred family selection in full-sib reciprocal recurrent selection
Theoretical and Applied Genetics, 1982A method (CRRS) that combines S2 and crossbred family selection in full-sib reciprocal recurrent selection (FSRRS) is proposed. The method requires four generations per cycle in single-eared maize populations. Selection is based on performance of S2 and full-sib families by applying selection index theory.

Variation among Full‐sib Families of Corn for Different Generations of Inbreeding
Crop Science, 1991Recurrent selection for improvement of yield of corn (Zea mays L.) germplasm emphasizes early testing of either S0 or S1 progeny testcrosses. On the basis of early testing information, progenies are selected and intermated to form populations for continued selection.

Physiological adjustment of two full-sib families of ponderosa pine to elevated CO2
Tree Physiology, 1993Seeds from two full-sib families of ponderosa pine (Pinus ponderosa) with known differences in growth rates were germinated and grown in an ambient (350 micro l l(-1)) or elevated (700 micro l l(-1)) CO(2) concentration. Gas exchange at both ambient and elevated CO(2) concentrations was measured 1, 6, 39, and 112 days after the seed coat was shed ...

Growth, phenology, and cold hardiness of 32 Douglas-fir full-sib families
Canadian Journal of Forest Research, 2009Thirty-two full-sib families of coastal Douglas-fir ( Pseudotsuga menziesii (Mirb.) Franco var. menziesii) with a range of predicted breeding values were monitored for growth rate, phenology, and cold hardiness over 2 years on two sites to investigate if other traits are being selected when family selection is based on height.

A hidden Markov model approach to multilocus linkage analysis in a full-sib family
Tree Genetics & Genomes, 2010Statistical packages for constructing genetic linkage maps in inbred lines are well developed and applied extensively, while linkage analysis in outcrossing species faces some statistical challenges because of their complicated genetic structures. In this article, we present a multilocus linkage analysis via hidden Markov models for a linkage group of ...

Genetics of cold hardiness in a cloned full-sib family of coastal Douglas-fir
Canadian Journal of Forest Research, 2000Variation in cold-hardiness traits, and their extent of genetic control and interrelationships, were investigated among individuals (clones) within a single large full-sib family of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from Oregon.

Parentage testing of hybrid full-sib families ofEucalyptuswith microsatellites
Scandinavian Journal of Forest Research, 2009Abstract This parentage verification study was carried out on 14 full-sib families of Eucalyptus species. Verification of the correct paternity and maternity is a key step in accurately estimating quantitative genetic parameters as well as efficiently genotyping for genetic linkage map construction and phenotype assessment.
