摘　　要：分析了江苏省历年来审定(鉴定)的28个花生品种系谱及其农艺性状的演变。结果表明:江苏花生育成品种共涉及34个亲本,其中,18个亲本来自江苏,23个亲本是育成品种,伏花生和徐州68-4是江苏花生品种的骨干亲本。在筛选优良地方品种基础上,二十世纪70年代以来江苏花生育成品种其株高和侧枝长呈增加趋势,2000年以后又明显降低;单株结果数、单株生产力持续增加,百果重和百仁重呈现高—低—高的变化趋势,总分枝数、出仁率和粗脂肪含量变异度较小。Pedigree analysis and the changes of agronomic traits were studied based on the data of 28 peanut varieties registered in Jiangsu from 1950 to 2009.The results showed that 34 varieties were used as parents for peanut breeding,and 18 parents were originated from Jiangsu,23 parents were registered varieties.Fuhuasheng and Xuzhou 68-4 were milestone parents for peanut breeding in Jiangsu.Based on the peanut landrace selected with good agronomic traits,plant height and length of lateral branching of peanut varieties registered in Jiangsu were increased after 1970＇s,then decreased since 2000.Number of pods per plant and yield per plant were increased,and 100 pod weight and 100 kernel weight underwent changing with high-low-high.The variability of kernel production rate,total branches per plant and crude fat content were stability from 1950 to 2009.
