Genetic variation for carcass quality traits in cultured sea bass (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Saillant, Eric; Dupont-nivet, Mathilde; Sabourault, Marie; Haffray, Pierrick; Laureau, Stanislas; Vidal, Marie-odile; Chatain, Beatrice.
Genetic parameters for carcass quality traits were estimated in 27 families of sea bass (3 dams x 9 sires factorial mating design), raised mixed in the same tanks starting before hatching. O. spring parentage was determined a posteriori using 6 microsatellite loci. Carcass quality traits were recorded at 818 days post fertilization (mean standard length: 32.6 +/- 3.1 cm). Genetic parameters were estimated from the sire half sib variance and covariance components. Heritability of body weight (BW) and carcass processing traits (standardized to body weight) percent head weight (Head%), percent viscera weight (Viscera%) and percent visceral fat weight (VisceFat%) were relatively high ranging from 0.48 +/- 0.15 (Viscera%) to 0.87 +/- 0.23 (Head%); the estimate...

Marqueurs microsatellites chez l'huître plate Ostrea edulis l. : caractérisation et applications à un programme de sélection pour une résistance au parasite Bonamia ostreae et à l'etude de populations naturelles

Autores: Launey, Sophie.
The flat oyster Ostrea edulis L. is the indigenous oyster of the Atlantic as well as the Mediterranean coasts of Europe.  Its commercial exploitation dates back to Antiquity but its breeding is now threatened by two parasitic protozoa, among which Bonamia ostreae. Various aspects of the genetics of this species' natural and farmed populations have been studied with the aid of microsatellite markers.  At first, the implementation and the screening of two partial genomic libraries made it possible to identify 28 new microsatellite loci. Analysis of the segregation of 12 of these loci and of two enzymatic loci shows that most microsatellite loci are transmitted in a Mendelian way, but some loci have significant segregation distortions. Moreover, seven linkage...

Estimates of heritability and genotype-environment interactions for body weight in sea bass (Dicentrarchus labrax L.) raised under communal rearing conditions
Provedor de dados: 5
Autores: Saillant, Eric; Dupont Nivet, Mathilde; Haffray, Pierrick; Chatain, Beatrice.
Genetic parameters for somatic growth rate in sea bass were estimated in two experiments where 27 (year-class 1997) to 30 (year-class 1998) families of sea bass (3 dams mated with 9-10 sires according to a full factorial design) were raised mixed in the same tanks starting shortly before hatching (48 h post fertilization). Trials were performed under two temperature (experiment 1, 1997: group high temperature (HT) and group low temperature (LT)) and two density regimes (experiment 2, 1998: group high density (HD) and group low density (LD)) with a subset of the mating design (18 families) being reproduced in the two experiments. All the fish were genotyped at 3-6 microsatellite loci which allowed them to be assigned to the individual breeders used in the...

Genetic purity certificate in seeds of hybrid maize using molecular markers
Provedor de dados: 95

One of the main features that confer high quality to the seed is its genetic purity, in which one of the major causes of contamination is the self-pollination of the female parent. Up to date, there is no accurate and fast methods for detecting such contamination. Thus, this work was carried out to certify the genetic purity in seeds of hybrid maize using different biochemical and DNA-based markers. Two single-cross hybrids and their parental lines derived from the maize breeding program at UFLA were evaluated by isoenzymatic pattern of alcohol dehydrogenase (ADH), esterase (EST), acid phosphatase (ACP), glutamate-oxaloacetate transaminase (GOT), malate dehydrogenase (MDH), isocitrate dehydrogenase (IDH), phosphoglucomutase (PGM), 6-phosphoglucomate...
