Abstract:
Soybean morphology and yield-related traits are important breeding targets. The corresponding ecological genotypes are suitable to specific nitrogen usage condition. In order to clarify the genetic basis of morphological and yield-related traits under different nitrogen levels, the 156 RILs derived from cross Dong L13 × Henong 60 were planted under normal and zero nitrogen usage in three environments. And we analyzed the QTL controlling the plant height, number of nod of main stem, number of pods per plant, number of seeds per plant, 100-seed weight, and seed weight per plant. The results showed that there were significant differences between the two parents in each trait, and each trait of RIL population followed normal distribution with the genetic characteristics of quantitative traits. A total of 71 QTLs were detected by QTL analysis, which explained the phenotypic variation of 3.88%-41.12%. Six QTLs were detected under normal and no nitrogen application, 29 QTLs were detected under non-nitrogen application, and 42 QTLs were detected under nitrogen application. In this study, 45 QTLs of the detected regulatory traits were newly discovered. The results of the present research would provide theoretical and technological support for molecular breeding on nitrogen ecotype in soybean.
