化学诱变剂 NaN_3首先由 Nilan 等在大麦中证实它是一种高效的化学诱变剂。长谷川,M.Afwar,Awan等分别在水稻上进行了诱变试验,认为 NaN_3在水稻遗传和育种实践中是一种有效的诱变剂。但在国内,NaN_3对水稻诱变效应的资料甚少。本试验旨在探索 NaN_3诱发水稻抽穗期、株高突变的效果,为诱变育种提供科学依据。 The chemical mutagen NaN_3 was first identified by Nilan et al in barley as an efficient chemical mutagen. Hasegawa, M.Afwar, Awan, respectively, in rice mutagenesis experiments that NaN_3 rice genetic and breeding practice is an effective mutagen. However, there is little data on the mutagenic effects of NaN_3 in rice in China. The purpose of this experiment is to explore the effect of NaN_3 inducing the heading date and plant height mutation in rice and to provide a scientific basis for mutation breeding.
