    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,以彩鲫做父本的F1的消化水平高于以彩鲫做母本的F1,且两种F1的消化水平均高于两个亲本,体现出了杂种优势。

    Abstract:

    We obtained the hybrids through the full red body color of the colorful carps hybridizing with the Jian carps by the reciprocal cross.We 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.This study 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(♂).They were named group 1, group 2, group 3 and group 4.The fish in each group had similar age in days. Each group chose five fish which had the similar weight to measure the intestines length and intestines weight and then made intestinal biopsies.And we calculated the indexes of intestinal weights and lengthes and the heights of duplicatures and other data.We disposed data by the Excel and analyzed data by the SPSS (17.0).Results showed that the rate of digestion of the F1 hybrids of the colorful carp(♂) and the Jian carp(♀) were higher than the rate of digestion of the F1 hybrids of the colorful carp(♀) and the Jian carp(♂) and that the rate of digestion of the two kinds of hybrids is higher than the rate of digestion of the two kinds of parental generations.And this reflected hybrid vigour.
