In order to explain clearly the variation status of embryo from tetrapoid Robinia pseudoacacia and fully use the variation resource initiated in the sexual reproduction of TRP in the further improvement of TRP, the classification and vitalities of seed embryos from tetraploid Robinia pseudoacacia were studied. The main results are as follow. According to the cotyledon number, color and plumpness, the seed embryos of TRP could be divided into 5 types: YVT (yellow, very replete,2 cotyledons), YMT( yellow, more replete,3 cotyledons ), YRF ( yellow, replete,4 cotyledons ), GNT ( green, no-replete, 2 cotyledons ) and WNT ( white, no-replete, 2 cotyledons ).

为了阐明刺槐同源四倍体种子胚变异状况及充分利用刺槐同源四倍体有性过程创造的变异资源对四倍体刺槐进行遗传改良，研究了刺槐同源四倍体种子胚类型及其生活力特征，主要结论如下：刺槐同源四倍体种子胚按照子叶数量、颜色及饱满程度，可以划分出5个类型：黄二、黄三、黄四、绿二及白二，所有类型种子胚混合平均单胚重量接近二倍体的1/2。
