1976年以来,应用~(60)C_0-υ射线处理珍珠矮11号干种子,自M_2代开始严格的选择已经培育出两个优良品系,另有六个品系,虽有某些缺点,但比对照显著增产。现将研究结果小结如下: 材料和方法 (一)材料:供试品种为珍珠矮11号原种由省农科院提供并由用~(60)C_0-υ辐射室照射干种子200克,剂量为2.5万伦、剂量率为103伦/分。 (二)试验方法:M_1代1976年3月照射干种子,当年进行单株种植。收获时,除去20％以上不孕株外,其余均取其主穗中部
Since 1976, the treatment of ~ (60) C_0-υ ray treatment of pearl short dwarf seeds No. 11, since M_2 generation strict selection has been bred two excellent strains, and another six strains, although some shortcomings, but the ratio Control significantly increased production. The results of the study are summarized as follows: Materials and methods (a) Material: The test varieties for the pearl short 11th species provided by the Provincial Academy of Agricultural Sciences by ~ (60) C_0- 2.5 million Lun, the dose rate of 103 Lun / min. (B) test methods: M_1 generation in March 1976 irradiation of dry seeds, planting single plant that year. Harvest, remove more than 20% of the infertile strains, the rest were taken from the middle of the main ear
