Opaque-2突变基因(o2)对玉米组合品质的影响
Nutritional Quality of the Corn Combinations with Mutant Gene Opaque-2 (o2)
摘要
Abstract
[Objective] This study aimed to investigate the action of mutant gene ol and its effect on nutritional quality of different corn cumbi-nationa. [ Method] A total of 33 normal com combinations from 18 inbred lines were compared with 33 combinations including gene o2 from the corresponding o2 near-isogenic lines (o2-NILs), to study the effect of ol gene introduction on grain quality of corn combinations. [Result] The contents of lysine, protein and oil in o2-NILs combinations were greatly more than that of normal com combinations. Except for ly-sine content, contents of other 14 amino acids changed- Contents of aspartic acid, threonine, glycine, isoleucine, histidine, arginine and pro-line improved; while contents of serine, glutamic acid, alanine, valine, leucine, tyrosine and phenylalanine decreased. Correlation analysis showed that contents of aspartic acid, arginine and threonine had the highest correlation with lysine content. Protein and oil contents had higher correlation with lysine content (0-48 and 0.38). Analysis of 33 o2-NILs combinations revealed the 61 combinations CAI58 x Ji477and CA156 x 196 showed high comprehensive quality and high yield with greater development potential. [Conclusion] This study will provide theoretical and material basis for improving the quality of temperate maize gerniplasm by introducing o2 gene.关键词
