Analysis of Embryo, Cytoplasmic and Maternal Effects on Seven Essential Amino Acid Traits in Rapeseed

Genetic effects on 7 essential amino acids – threonine (Thr), methionine (Met), phenylalanine (Phe), isoleucine (Ile), valine (Val), leucine (Leu) and lysine (Lys) in rapeseed were analyzed using the genetic model that includes diploid embryo, cytoplasmic and diploid maternal effects on quantitative traits of diploid plant seed via a diallel design with 8 parents of Brassica napus. The results demonstrated that the contents of Thr, Met, Phe and Ile in rapeseed were mainly controlled by the maternal effects, while the others were mainly affected by the cytoplasmic effects, the embryo effects for the contents of 7 essential amino acids were all not the largest among the different genetic systems.
