Shorthorn cattle (DJ) and Angus cattle (AG) are originated from UK.
短角(DJ)、安格斯(AG)牛原产于英国[1];一九九六年云南省家畜冷冻精液站从澳大利亚分别引进DJ、AG种公牛各4头,一九九七年对8头种公牛采精均获得成功,经过对两品种公牛繁殖性能及适应性分析,DJ种公牛较AG种公牛表现出较明显的优势。

In this study, three amphidiploids and three diploids in the "U-Triangle" of Brassica plants were used, and style, stigma size, stigma development, the development of basic pod characters, seed and cotyledon cell development were studied from the view of evolutionary developmental biology.
本研究论文以芸薹属(Brassica)植物“禹氏三角”关系中的3个多倍体复合种和3个二倍体基本种为材料,从进化与发育生物学的角度,对这些多倍体和其祖先二倍体的花柱大小、柱头发育、角果基本性状发育、种皮发育及子叶发育等进行了研究,所得主要研究结果如下: 通过比较分析多倍体复合体与其祖先二倍体基本种在花柱、柱头大小、角果长度、宽度与表面积、种子直径及种子干重上的异同,得到多倍体复合种的发育规律是:有的多倍体品种如0857和1219偏向其祖先二倍体两个亲本之一的方向发育,而品种2685则是处于其两个亲本之间的趋势发育。
