水稻镉砷累积的基因型和环境互作效应分析
Responses of cadmium and arsenic accumulation in rice to cultivar-environment interactions
摘要
Abstract
Screening stable rice cultivars with low accumulation of cadmium(Cd)and arsenic(As)is an effective means to promote safe rice production.In order to obtain stable rice cultivars with low Cd and As accumulation and provide a reference for screening and identification methods,the effects of different environments on Cd and As contents of nine main rice varieties were studied.The results showed that Cd and As accumulation amounts in rice were affected by both genotype and the environment,and the effect of environmental heterogeneity on Cd and As accumulation in rice was significantly greater than that of rice genotype.GGE biplot analysis combined with yield score evaluation could effectively screen out rice cultivars with high productivity and stable low heavy metal accumulation.The contributions of the environment and genotype interaction to Cd and As contents in rice grain were 99.91%and 79.70%,respectively.The contribution of environmental heterogeneity to Cd and As contents in rice grain was 83.46%and 56.56%,respectively.Two screening sites(S1,S2)of rice varieties with low Cd accumulation and four screening sites(S1,S2,S3,S6)of rice varieties with low As accumulation were selected through the combination of GGE biplot combined with yield score evaluation.Three low As accumulation varieties(V1,V4,V9)and one low Cd accumulation varietys(V7)with higher productivity were selected.The results of this study indicate that the use of GGE biplot combined with yield score evaluation provides a new economical and feasible method for selecting test sites and screening rice varieties with low accumulation of Cd and As.关键词
