摘要
在多年近交系选育的基础上,以纯度较高、具不同优良性状的C、D、R、H四个近交系为亲本杂交培育成“松丹1号、2号”双交种蜜蜂,群均产蜜量分别比美意蜂增加70.8%和54.4%,产王浆量增加14.4%和23.7%,越冬群势削弱率降低11.9%和5%,饲料消耗量降低23.7%和14.9%。在生产中表现出较强的优势。
Songdan Ⅰ,Ⅱ bee double-hybrids have been crossed from four inbred line C,D,R,H,which have been done with inbreeding for many years and possessed different fine character and higher pure.As compared with American-Italian bee:a per colony honey and royal Jelly yield were increase 70.8%,54.4% and 14.4%,23.7% respectively,Lostrare of colony and consumed-fodder of colony reduced 11.9%,5.0% and 23.7%,14.85% respectively during winting period.A superior productivety were displajed by Songdan Ⅰ,Ⅱ bee double-hybrids.
