【摘要】 苜蓿新品系RS(Root selection)是经过根选培育而成,50%的植株没有明显的主根,而是分枝根或侧根。1999-2002年,在中国农业科学院畜牧研究所试验地,将国内外8个高产紫花苜蓿品种:中苜1号、秘鲁、保定、WL323、WL320、RS、Queen、德国(国外品种)苜蓿,进行了品比试验,对其产量进行分析研究,结果表明:RS与其它7个苜蓿品种相比分别比中苜1号、秘鲁、保定、WL323、WL320、Queen、德国(国外品种)产量提高0.97%~52.5%、5.9%~56%、14.3%~42.6%、.6%~46.2%、0.97%~43.6%、0.77%~42.6%、7.0%~37.3%。在北京地区表现了较高的产草量性能和适应性。表明选育效果良好,育成根系发达的丰产苜蓿新品系。更多还原

【Abstract】 New high yield alfalfa strain was developed by root selection.There are secondary roots in fifty percent plants.Comparative test has been done about eight high yield alfalfa cultivars of home and overseas in test plot in Institute of Animal Science,CAAS.Cultivars include ZhongmuⅠ,Bilu,WL323,WL320,Queen,Germen,RS,Baoding.Results have indicated new alfalfa strain RS has higher yield than other cultivars.It’s yield increases respectively by 0.97%~52.5%,5.9%~56%,14.3%~42.6%,2.6%~46.2%,0.97%~43.6%,0.77%~42.6%,7.0%~37.3% than ZhongmuⅠ,Bilu,WL323,WL320,Queen,Germen,Baoding.This new strain RS shows better adaptation in Beijin area.The experiment has indicated the better effect of selected breeding,and bred new high yield alfalfa strain which has flourishing root system with abundant secondary root,but without obvious main root.更多还原
