Interactive effect of genotype and environment on the genetic covariance of characterization of heavy metal accumulation in edible rice grain(Oryza sativaL.)

The interactive effect of genotype and environment on the genetic covariance of characterization of heavy metal accumulation in edible rice grain(Oryza sativa L.) was conducted by using genetic models for quantitative traits of seed. The results show that the genotype covariance appeares to be positive between these 5 heavy metal contents of Hg, As, Cr, Cd and Pb. The genetic covariance and GE interaction covariance are positive or negative to different degrees between pairs of element contents.
