以国槐为供体，花生栽培品种79266和辐8707为受体，采用花萼管注射法和柱头浸滴法将供体DNA导入受体。D1代变异率33．3％～63．4％，变异的性状包括单株果数、果形、果大小、内种皮颜色、株型、叶形、熟性、育性及产量性状。D2的大部分变异株能稳定遗传，不再分离，稳定株行占D2株行的75％～96％。试验表明，国槐DNA导入花生栽培品种，可以引起后代的变异，变异范围广，稳定快，是花生品种改良和创造新种质的有效方法途径。
The donor of Sophora japonica, peanut cultivars 79266 and 8707 were used as recipients. The donor DNA was introduced into the recipient by calyx tube injection and stigma infusion. The variation rate of D1 generation ranged from 33.3% to 63.4%. The variation traits included single fruit number, fruit shape, fruit size, inner seed coat color, plant type, leaf shape, ripeness, fertility and yield traits. Most of D2 mutant strains can be inherited stably without separation, and stable strains account for 75% to 96% of D2 strains. Experiments showed that the introduction of Sophora japonica DNA into peanut cultivars can cause the variation of offspring, with a wide range of variation and stability. It is an effective way to improve peanut varieties and create new germplasm.
