1. The experiments about the parthenogenesis induced by delay-pollinating and radiating of X-ray, were conducted. 2. The fertility of pistilate flowers decreased with days from silking, and the parthenogenesis could be induced by delay-pollinating after this rapid decreasing of fertility. 3. A few kernels were parthenogenically obtained by application of pollens radiated by X-ray, but there was no significant differences among the lots of X-ray treatments. 4. It did not reveal accumulative effects to use delay-pollination and X-ray radiation simultaneously. 5. Number of chromosomes of plants developed from the parthenogenic kernels, was 20 (2n). 6. Therefore, it may be concluded that the parthenogenesis induced artificially by these methods belongs to the category of diploid pseudogamy.
