【摘要】 甜菜优异种质79018是由中国农业科学院甜菜研究所经过人工杂交创制获得的资源材料。于1997～1998年参加黑龙江、辽宁、山西和内蒙古等4个试验点的异地鉴定试验,其中有3个试验点的平均根产量比统一对照品种甜研302增产21.6%以上;有2个试验点的平均含糖率比对照品种甜研302提高0.25度和0.42度;所有4个试验点的平均产糖量比对照品种甜研302增产13.4%～33.3%;有3个试验点的平均褐斑病病情都低于对照品种甜研302褐斑病病情0.5级以下。由此表明,该甜菜优异种质具有丰产性、抗褐斑病及适应性好等特点。于2001年被农业部评为“农作物一级甜菜优异种质”。更多还原

【Abstract】 Excellent sugar beet germplasm79018is the seed resource material that was obtained from artificial crossing by Sugar Beet Research Institute of CAAS.It was tested in the different regional recognition experiments in four experimental locations(Heilongjiang,Liaoning,Shanxi,Neimeng)during1997～1998,the average root yield increased more than21.6%than check variety Tianyan302among three experimental locations;The average sugar content increased0.25and0.42than check variety Tianyan302in two experimental locations;the average sugar yield increased13.4%～33.3%than check variety Tianyan302in all experimental Locations;the average disease index of Leaf spot was lower below0.5scale than check variety Tianyan302.Those showed:the excellent sugar beet germplasm has characters like as high yield,high disease resistance of leaf spot and good suitability.It was called as the first class sugar beet excellent germplasm of farm crop by the Department of Agriculture in2001.更多还原
