摘要
以烤烟品系LY 1306-A,LY 1306-B,LY 1306-C三个相关姊妹系为材料,利用辐照诱变处理种子,以期从中筛选出株系优良、抗性显著的烤烟品系。通过对3个姊妹系烤后烟叶的质量评价,选择具有潜力的品种(系)进行辐照诱变,根据大田长势筛选优异单株,获得优异株系。结果表明,LY 1306-A品系的质量优于其他2个姊妹系,抗辐照能力较强,并由辐照后LY 1306-A经田间筛选获得3个优异株系AM2-10,AM2-12与AM2-40。
To select the elite flue-cured tobacco line with good quality and strong resistance to disease,3 tobacco lines,LY 1306-A,LY 1306-B and LY 1306-C from the same background selection process were used as materials to be subjected to the electron beam irradiation and then the elite lines were selected among the treated seeds.The results showed that in the three lines LY 1306-A had better quality and stronger resistance to electron beam irradiation.Based on the fields performances three mutagenic lines AM2-10,AM2-12 and AM2-40 were selected from the progeny of LY 1306-A treated seeds.Results indicated that electron beam irradiation induced the increase of the resistance to field diseases in the M2 generations.
