在四国爱媛县南部地区新发现的日本本土鸡群。对121只鸡进行了外形性状测定和血液采集。鸡的体型很小，成年雄鸡重1091克，成年雌鸡重796克。这种鸡的羽毛和皮肤颜色比Tosajidori更多样化，Tosajidori是日本最古老的本土鸡品种之一，起源于四国的高知县。C、e+、s、Mo、w和ld在种群的5个多态位点中频率较高，而这些位点在Tosajidori中为单态位点。采用淀粉凝胶或聚丙烯酰胺凝胶电泳对血液样本进行蛋白质多态性分析。在Tf、Alb、PasA、Akp、Akp-2、Es-1、Amy-1、Ct和6-PGD等9个位点中观察到多态性。根据遗传距离绘制了一种树状图来阐明44个鸡品种或群体的系统发育关系。爱媛土鸡种群与Tosajidori、Ohiki （Minohikichabo）和Koshamo的亲缘关系较近。早期的Tosajidoris在羽毛、皮肤和耳垂颜色上更具多态性，与爱希米土著人口相似。人口的目前特征可能反映了Tosajidori的原型。这表明爱媛本地鸡种群（我们建议将其命名为Ehimejidori）和Tosajidori来自一个共同的祖先。(日本。幼禽。科学。农业学报，37:101-107,2000)
Japanese native chiken population is newly found in southern region of Ehime Prefecture in Shikoku. The measurments of external traits and the collecting of blood samples from 121 birds were performed. Size of the chickens was small, weighing 1,091 g for adult males and 796g for adult females. The population varied in plumage and skin colors more than the Tosajidori, one of the oldest Japanese native chicken breed, and originating in Kochi Prefecture, Shikoku. High frequencies of C, e+, s, Mo, w and ld were always ovserved in the five polymorphic loci of the population, whereas these loci were monomorphic in the Tosajidori. Blood samples were analyzed for protein polymorphisms by starch gel or polyacrylamid gel electrophoresis. Polymorphisms were observed in nine loci, that is Tf, Alb, PasA, Akp, Akp-2, Es-1, Amy-1, Ct and 6-PGD. A dendrogram based on genetic distances was drawn to elucidate phylogenetic relationships of 44 breeds or populations of the chickens. Relative close relations were ovserved among the Ehime native chicken population, the Tosajidori, the Ohiki (the Minohikichabo) and the Koshamo. The Tosajidoris in ealier days were much more polymorphic in plumage, skin and ear lobe colors, and were similar to the Ehime native population. The present feature of the population may reflect a prototype of the Tosajidori. It is suggested that the Ehime native chicken population (which we propose to name the Ehimejidori) and Tosajidori deriverd from a commom ancester.. (Jpn. Poult. Sci., 37: 101-107, 2000)
