摘要
本研究用25 Gy和30 Gy的60Co-γ射线辐照处理莱芜大姜和金昌大姜的萌动根茎与幼芽根茎,并系统分析了其VM1、VM2和VM3代材料的田间表现。结果表明,辐照处理对VM1和VM2代的抑制效应明显,且剂量越大抑制作用越强。两品种的萌动根茎对辐照处理更敏感,诱变效应更强。莱芜大姜幼芽根茎的临界剂量为25 Gy,是对莱芜大姜幼芽根茎进行辐照诱变处理的适宜剂量。金昌大姜的临界剂量低于25 Gy。筛选出了2个增产20%以上的高产突变株系GDC2531和PZC3026。
The fresh rhizome and germination rhizome of two ginger cuhivars, Laiwudajiang and Jinchangdajiang were irradiated with 25 Gy and 30 Gy doses of ^60Co-γrays and the field performance of VM1 to VMs generations were studied. The significant inhibition effect of ^60Co-γrays on the VM1 and VM2 generation was found to be increasing with the increase of dose. The fresh rhizomes of the two cultivars were more sensitve to the irradiation and their mutagenic effect were more conspicuous than that of germination rhizome. The critical dose of Laiwudajiang germination rhizome with 40% survival rate was found to be 25 Gy while that of Jinchangdajiang was below 25 Gy. Two mutantion lines with high yield, GDC2531 and PZC3026, were selected, whose yields were over 20% more than that of CK.
