Effects of two-locus combinations, using the « roux », « lavender » and « beige » mutations, on plumage color of Japanese quail Inra
Minvielle, F.; Gourichon, D.; Monvoisin, J.L..
The interactions between the effects of three plumage color mutations taken two-by-two (sex-linked recessive roux,autosomal recessive lavender, and autosomal dominant beige) were studied in Japanese quail by producing a total of 121 F1and 1118 F2 quail from the three pure stocks. Three new plumage colors were obtained in F2 quail: roux-diluted beige,cream, and lavender-diluted beige. Two of them, roux-diluted beige (from the roux and beige mutations) and cream (fromthe roux and lavender mutations) corresponded to double homozygotes or hemizygous birds, and could therefore be usedto tag a quail line. On the other hand, an F3 from F2 birds with lavender-diluted beige plumage was necessary to show thatquail with this plumage color were homozygous for the...

Effets quantitatifs associés au gène albinos lié au sexe chez la Caille japonaise Inra
Merat, P.; Bordas, A.; Jonon, F.; Perramon, A..
Deux années successives (1979 et 1980), des cailles femelles (Coturnix coturnix japonica), les unes de type sauvage, les autres, soeurs ou demi-soeurs des premières, portant le gène sal (albinos lié au sexe), ont été comparées pour la survie en fin d’incubation et après l’éclosion, l’activité en open-field, et divers paramètres quantitatifs mesurant la croissance pondérale, la production et les qualités des oeufs, l’efficacité alimentaire en cages individuelles, enfin l’état du plumage des pondeuses après transfert en cages collectives. Les albinos comparées aux cailles pigmentées présentent une mortalité nettement plus élevée après l’éclosion. Ce phénomène se limite aux premières semaines d’élevage et disparaît après 5 semaines d’âge. Leur...

Microsatellite mapping of QTL affecting growth, feed consumption, egg production, tonic immobility and body temperature of Japanese quail Inra
Minvielle, F.; KAYANG; INOUE-MURAYAMA; MIWA; Vignal, A.; Gourichon, D.; Neau, A.; Monvoisin, J.L.; ITO.
Background: The Japanese quail (Coturnix japonica) is both an animal model in biology and a commercialbird for egg and meat production. Modern research developments with this bird, however, have beenslowed down by the limited information that is available on the genetics of the Japanese quail. Recently,quail genetic maps with microsatellites and AFLP have been produced which open the way to comparativeworks with the chicken (Gallus gallus), and to QTL detection for a variety of traits. The purpose of thiswork was to detect for the first time QTL for commercial traits and for more basic characters in an F2experiment with 434 female quail, and to compare the nature and the position of the detected QTL withthose from the first chicken genome scans carried out...

Two new plumage mutations in the Japanese quail : « curly » feather and « rusty » plumage Inra
Minvielle, F.; Gourichon, D.; Moussu, C..
Background: The genetics of plumage of Japanese quail is of interest both from a biologicalstandpoint, for comparative studies between avian species, and from a zootechnical standpoint, foridentifying commercial selection lines or crosses. There are only few plumage mutations reportedin quail, and the present work describes a new color variant "rusty" and a new feather structure"curly", and their heredity from an F1 and F2 segregation experiment.Results: Curly feathers result from abnormal early growth caused by transient joining of folliclewalls of adjacent feathers around 10 days of age, but the expression of the trait is variable. Rustyplumage color results from the replacement of the wild-type plumage pattern on the tip of thefeather by a reddish...
