摘　　要：[Objective] The aim of this study was to observe the agronomic,yield and quality traits of Ningchun 4 and its parents under the same environmental conditions,as well as to carry out molecular detection on the background genes distribution of the corresponding traits.[Method]Ningchun 4 and its parents Sonora 64,Hongtu,Abbondanza,Quality were used as materials to detect the agronomic and quality traits,as well as to analyze the genetic variation laws by molecular determination method.[Result]Ningchun 4 had inherited the advantages of bigger spike,red and hard grain from Sonora 64 and higher 1 000-grain weight from Hongtu.However,it had also inherited the disadvantages of late-maturing from Sonora 64 and lower tillering ability from Hongtu;the grain quality of Ningchun 4 was slightly lower than the Sonora 64;Ningchun 4 had high quality subunit of 5＋10,which had good dough rheological properties.[Conclusion]Ningchun 4 had inherited the long photoperiod characteristics and no-resistant to slow-leaf rusting and stripe rust characteristics from Hongtu and low PPO activity,high yellow pigments content from parents.[目的]研究在同一环境条件下宁春4号及其亲本的农艺、产量及品质性状表现,并对其相关性状的背景基因分布进行分子检测。[方法]以宁春4号及其亲本索诺拉64、宏图、阿勃碧玉麦为材料,对其农艺性状、品质性状进行测定,并用分子检测法对其遗传变异规律进行分析。[结果]宁春4号遗传了索诺拉64大穗,红粒,硬质和宏图千粒重高等优点,同时也遗传了索诺拉64晚熟宏图分蘖力低等缺点;宁春4号籽粒品质略低于索诺拉64;宁春4号具有5+10的优质亚基,具有良好的面团流变学特性;宁春4号遗传了宏图长光周期特性和不抗慢叶锈和条锈特性及双亲低PPO活性、高黄色素含量。[结论]该研究结果为小麦种质资源的遗传分析奠定了基础。
