Effects of Genotypes and Environments on Pentosan Content and RVA Viscosity of Wheat

Ten traits in the grains of ten wheat varieties(lines) planted in five environments,including total pentosan(TP),water-soluble pentosan(WSP),water-insoluble pentosan(WIP) and seven RVA viscosity traits,were determined to investigate their correlation and the effect factors.The results showed that all the ten traits were affected by the genotypes,environments and their interaction.Genotypic(G) variances and environmental(E) variances were significant or greatly significant difference,G×E variances was greatly significant difference for WSP and seven RVA viscosity traits.In pentosan content traits,environmental variation was more than genotypic variation,and G×E variation was the smallest;While,genotypic variations were more than environmental variations for all the seven RVA viscosity traits.WSP content was negatively and significantly correlated with the peak viscosity.The effects of genotype and environment were discussed in grain traits of wheat quality breeding and new wheat varieties selection breeding.
