远缘杂交不亲和性使胚败育成皱缩种子,杂种虽受精正常,胚早期也发育,但因胚乳发育不良或异常导致杂种胚不成熟而死亡。胚培养可在败育前取出胚进行培养,使之成为植株。花生属有些种和杂种的胚培养现状见表1。 Distant incompatibility of the embryo aborted embryos into crimple seeds, hybrids normal fertilization, early embryo also developed, but due to endosperm dysplasia or abnormalities leading to hybrid embryos immature and died. Embryo Culture Embryos can be removed prior to abortion and cultivated to become plants. Peanut species and hybrid embryo culture status in Table 1.
