选择硫苷性状差异较大,而其它品质性状和农艺性状相近的油菜品系967H和967L为材料,探讨了甘蓝型油菜对辐射的敏感性与硫苷含量的关系。结果显示,低硫苷品系比高硫苷品系对辐射敏感。967H的800Gy、1 000Gy和1 200Gy辐射处理发芽率均极显著高于967L;967H的这三种辐射剂量处理成苗率比967L分别高9.8%、19.8%和20.1%。相同剂量辐射处理对967L的M1和M2植株农艺性状的影响显著大于967H,对967L主要农艺性状产生显著影响的辐射剂量为800Gy以上,对967H主要农艺性状产生显著影响的辐射剂量为1 000Gy以上。967L辐射处理M2植株品质指标变化幅度和突变株发生频率均大于967H。

967H and 967L were used as materials because of their similar agronomic and other quality characteristics except their great difference in glucosinolate content. This study was to find out the correlation between glucosinolate content and sensitivity of irradiation in Brassica napus L. The results showed that the low - glucosinolate line was more sensitive to ^60Co γ rays irradiation than the high - glucosinolate line. The germination rate of 967H in the treatments with 800Gy, 1 000Gy or 1 200Gy irradiation was greater than 967L in a highly si...
