皂荚是山西省重要的乡土经济型树种，近几年对皂荚良种苗需求不断增大，选育良种迫在眉睫。山西省林业科学研究院乡土树种课题组科技人员从2008年开始，在山西省设11个点，以皂荚果刺两用为目标，通过初选、复选和决选，选出6株皂荚优树。通过6a的嫁接试验，对山西省6个产地的皂荚优良无性系的产量和经济性状指标进行测定和分析，并利用主成分分析法选出果刺两用皂荚最优品系为12号母树。嫁接5 a后，12号无性系单株产刺量1.06 kg，刺平均长度、平均粗度、平均重分别为16.21 cm，0.61 cm，4.84 g，荚果平均产量5.07 kg／株，荚果平均长度、平均宽度、平均厚度、平均重量、千粒重分别为23.41 cm，2.67 cm，1.08 cm，25.5 g，431.15 g.通过和母树比较，12号无性系保持了良好的遗传特性。
