日本鹌鹑(Coturnix Japan Onica)既是生物学上的动物模型，也是鸡蛋和肉类生产的商业鸟类。然而，对这种鸟的现代研究进展因可获得的关于日本鹌鹑遗传学的有限信息而放缓。近年来，利用微卫星和AFLP技术构建的鹌鹑遗传图谱已经问世，这为与鸡(Gallus Gallus)的比较工作以及对各种性状的QTL检测开辟了道路。这项工作的目的是在434只雌性鹌鹑的F2代实验中首次检测到商品性状和更基本的性状的QTL，并将检测到的QTL的性质和位置与最近几年进行的第一次鸡基因组扫描的QTL进行比较。CJA01的窝长、体重和采食量、CJA06的初产蛋龄和蛋数、CJA20的蛋壳重和剩余采食量在全基因组范围内都有显著或提示性的QTL，其中影响体重和采食量、初产蛋数和初产蛋龄的QTL可能具有多效性。在CJA01上发现了一个影响紧张性不动的QTL，在CJA01和CJA03上检测到了染色体范围内显著的体温QTL。在CJA02、CJA05、CJA09和CJA14上发现了其他染色体上显著的QTL。在CJA01上发现了体重和采食量的QTL的双亲效应。尽管长度有限，但第一个鹌鹑微卫星图谱有助于检测很少报告的性状的新QTL，如剩余饲料摄入量，并有助于建立本工作中检测到的用于采食量、体重和紧张性不动的QTL与GGA01上报道的鸡的QTL之间的一些对应关系。现在可以进行进一步的比较工作，以便更好地估计和了解这两个Phasianidae物种的遗传相似性和差异。
The Japanese quail (Coturnix japonica) is both an animal model in biology and a commercial bird for egg and meat production. Modern research developments with this bird, however, have been slowed 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 comparative works with the chicken (Gallus gallus), and to QTL detection for a variety of traits. The purpose of this work was to detect for the first time QTL for commercial traits and for more basic characters in an F2 experiment with 434 female quail, and to compare the nature and the position of the detected QTL with those from the first chicken genome scans carried out during the last few years. Genome-wide significant or suggestive QTL were found for clutch length, body weight and feed intake on CJA01, age at first egg and egg number on CJA06, and eggshell weight and residual feed intake on CJA20, with possible pleiotropy for the QTL affecting body weight and feed intake, and egg number and age at first egg. A suggestive QTL was found for tonic immobility on CJA01, and chromosome-wide significant QTL for body temperature were detected on CJA01 and CJA03. Other chromosome-wide significant QTL were found on CJA02, CJA05, CJA09 and CJA14. Parent-of-origin effects were found for QTL for body weight and feed intake on CJA01. Despite its limited length, the first quail microsatellite map was useful to detect new QTL for rarely reported traits, like residual feed intake, and to help establish some correspondence between the QTL for feed intake, body weight and tonic immobility detected in the present work and those reported on GGA01 in the chicken. Further comparative work is now possible in order to better estimate and understand the genetic similarities and differences of these two Phasianidae species.
