春谷辐射引变效应的研究

- Studies of Effect on Radiation Induced Spring Millet
- 摘要:
- 红谷和长农10号的干种子用60Coγ射线1万、2万、2.5万、3万、4万和5万伦照射。实验结果表明：两个谷子品种在 M1的存活率、苗高和胚根长度随着剂量的增加而下降。染色体畸变率和不育率随着剂量的增加而增加。在 M2中，长农10号的性状突变与剂量成正相关，突变体的性状稳定快。红谷的性状突变率与剂量关系不显著，突变体的性状不易稳定。在后代的突变体中我们选育出三个品种，比对照增产10—65.5%，现已大面积推广种植。
- Abstract:
- Dry seeds of Honggu and Channong 10 millet were exposed with 60Co gamma rays at 10 to 50 kR.The experimental results indicated that survival seedling hight and root length in M1 generation decreased as the radiation exposure increased.The chromosomal aberrantion and sterility and frequency of trait of Channong 10 in the M2 generation increased as the radiation exposure inereaed,but relationship between frequency of trait mutation of Honggu radiation exposure is not significance.Three new varieties were selected from the mutant and the acreage under cultivation is broad.The yield per mu of new varieties has been inereaed by 10-64.5% as compared with control grroup.
