Araneda, Cristián; Díaz, Nelson F.; Gómez, Gilda; López, María Eugenia; Iturra, Patricia (Sociedade Brasileira de Genética, 2012)Spawning time in salmonids is a sex-limited quantitative trait that can be modified by selection. In rainbow trout (Oncorhynchus mykiss), various quantitative trait loci (QTL) that affect the expression of this trait have ...

Colihueque, Nelson; Iturra, Patricia; Díaz, Nelson F.; Veloso Martínez, Alberto (1996)Gynogenetic haploid progenies of rainbow trout, produced using UV light for sperm inactivation, were studied in comparison with normal progenies. In a total of 437 normal embryos, 3.5% of them showed chromosome abnormalities: ...

Neira Roa, Roberto; Díaz, Nelson F.; Gall, Graham A. E.; Gallardo, José A.; Lhorente, Jean Paul; Manterola, Rodrigo (ELSEVIER, 2006-06-30)In this study the genetic response to selection and the effects of inbreeding oil harvest weight in two populations (which spawned as even and odd years classes) of Coho salmon are described. Artificial selection was ...

Neira Roa, Roberto; Díaz, Nelson F.; Gall, Graham A. E.; Gallardo, José A.; Lhorente, Jean Paul; Alert, Alejandro (ELSEVIER, 2006-06-30)Phenotypic records of within-year spawning date in two cultivated populations of coho salmon, named as even (n=2272) and odd (n=1347) year classes are analyzed. Both populations were selected for harvest weight and early ...
