摘　　要：通过对全红体色彩鲫(Carassius auratuas)与建鲤(Cyprinus carpio var.Jian)的正反交杂交后代进行消化道生长发育的比较研究,以期为建鲤与彩鲫的远缘杂交生产和研究提供理论依据。本实验选择建鲤亲本、彩鲫亲本、鲤鲫F1(建鲤♀×彩鲫♂)和鲫鲤F1(彩鲫♀×建鲤♂)各50条,每组实验鱼日龄相近。每组选5条体重相近的鱼测量肠长和肠重,并制作肠切片,计算肠重指数、肠长指数、肠道皱襞高度、绒毛长、绒毛宽、肌层厚度数据。数据结果采用SPSS(17.0)软件中的LSD法进行显著性检验。结果表明,以彩鲫作为父本的F1的消化水平高于以彩鲫作为母本的F1,且彩鲫作为父本的F1即鲤鲫F1的消化水平高于两亲本,体现出了杂种优势。We obtained the hybrids through hybridizing the full red body color carps（Carassius auratuas） with the Jian carps（Cyprinus carpio var. Jian） by reciprocal cross, and then studied the growth and development of the digestive tract of the two kinds of hybrids comparatively to provide the theoretical basis for the production and research of the distant hybridization of the colorful carp and Jian carp. We respectively chose 50 from the Jian carps, the colorful carps, the F1 hybrids of the colorful carp（♂） and the Jian carp（♀） and the F1 hybrids of the colorful carp（♀） and the Jian carp（♂）. The fish in each group had similar age. Each group contained five fish which had similar weight to measure the intestine length and intestine weight and then intestinal biopsies were made. We calculated the indexes of intestinal weight and length and the height of duplicatures and other data. We disposed data by the Excel and analyzed data by the LSD of SPSS（17.0）. Results showed that the digestion rate of the F1 hybrids of the colorful carp（♂） and the Jian carp（♀） was higher than that of the F1 hybrids of the colorful carp（♀） and the Jian carp（♂） and that the digestion rate of the F1 hybrids of the colorful carp（♂） and the Jian carp（♀） is higher than that of the two kinds of parental generations, which reflected hybrid advantage.
