Fertilization and Embryo Dvelopment in Hybridization Between wheat and Pearl millet
硬粒小麦与珍珠栗远缘杂交的受精作用和胚胎发育

The fertilization and embryo development in wide crosses of Triticum durum Desf. and Pennisetum glaucum syn. P. americanum were studied. In a sample of 192 florets fixed after pollination, 7. 81% had double fertilization and had embryo and endosperm, but endosperm development was slower than that of the embryos, 3.13% had only embryo and 1.04% had only endosperm. The frequency of fertilization and embryo formation were 11.98% and 10. 94%. Because the endosperms were abnormal, it was very difficult to produce viable mature seeds.
