Изучение эффекта гетерозиса у годовиков карпа по выживаемости и потере массы тела в зимний период

2009

Analysis heterotic effect in mixed bred one year old carps (Cyprinus carpio) (obtained after crossing of tremlyansky carp off-sets) on survival ability and body weight loss in winter period was realized in the conditions of the Republic of Belarus. It was determined that in each group of the analyzed crosses obtained by means of using of tremlyanski carp off-sets as parental and maternal components of crossings there were noted the substantial changes in indexes of body weight loss in winter period. There were determined crosses with high (till 17%) and low (till 0, 0%) statistically-valid meanings of the analyzed index. In both experimental variants in some crosses which were obtained by means of application of tremlyansky carp there was noted the heterotic effect which was expressed in lowering of body weight losses and increasing of carp survival rate in winter. Heterotic effect and heightened specific crossing ability in 2006/2007 experimental years were determined in combinations of tremlyansky mirror carp x mixture of mirror carps; mixture of mirror carps x tremlyansky scale; and mixture of scale carps x tremlyanski scale; in 2007/2008 experimental years - in reciprocal combinations of tremlyansky scale and German carps (German x tremlyanski scale and tremleanski scale x German), as well as in mixture of German x tremlyansky mirror carps, and tremlyansky mirror x mirror carps mixture. Tremlyansky carp adapted well to the conditions of pond farms of Belarus and could be recommended for industrial production in pure species
