Nine cytoplasmic , male sterile lines as females and five restoring lines as males were introduced in a diallel cross in two environments . It was found that the content of non-essential amino acids including Asp , Ser , Glu , Gly and Tyr were mainly controlled by genetic main effects , whereas the content of Ala or Pro was mainly affected by GE effects . In genetic main effects , the cytoplasmic and maternal genetic effects were preponderant for all traits of non-essential amino acids , indicating that selection for improving these traits based on the maternal plant would be more effective than on seeds . The total narrow-sense heritabilities for non-essential amino acids were 70 . 9-85 . 9% . By predicating the genetic effects of parents , the total genetic effects from Xieqingzao , V20 , Zuo 5 and Zhenshan 97 were mainly negative and these parents would decrease the content of most essential amino acids . Since parents of Zhenan 3 , Yinchao 1 , T49 , 26715 , 102 and 1391 had possessed a positive value of most total genetic effects , these parents could be chosen as optimal parents for increasing the content of most non-essential amino acids .
