本文报导关于“Jhona 349”דT(N)1”杂交种R_(2)代的分离,随后辐射其种子的情况。由于辐射的材料具有杂种种性,故定名为“突变杂种”。“突变杂种95号”的特征是:矮秆、极早熟、对光期及气温不敏感、高产、米粒蛋白质含量高。将500粒休眠F_2杂种种子用Co～(60)(钴～(60))γ——射线的50千拉得进行辐射处理,并于1966年夏天雨季种植R_1代。500粒种子中,有236粒发芽,其中有140株秧苗生长至成熟。每株 This paper reports on the isolation of the “Jhona 349” × “T (N) 1” hybrid R_ (2) generation and subsequent irradiation of its seeds. Due to the hybrid nature of the irradiated material, it is named “Mutant Mutant”. “Mutant Hybrid 95” is characterized by: dwarf, very precocious, insensitive to light and temperature, high yield, high protein content in rice. Five hundred dormant F_2 hybrid seeds were irradiated with Co ~ (60) (cobalt ~ (60)) γ - ray at 50 krad and R_1 was planted in the summer of 1966. Of the 500 seeds, 236 were sprouted, of which 140 were grown to maturity. Per plant
