Plant height (PH), spike length (SL) and compactness (SCN) are important agronomic traits in wheat due to their strong correlations with lodging yield. Thus, dissection of genetic basis is essential for the improvement plant architecture yield potential breeding. The objective this study was map quantitative trait loci (QTL) PH, SL SCN a recombinant inbred line (RIL) population derived from cross 'PuBing3228 × Gao8901' (PG-RIL) evaluate values these QTL improve yield.In current study, Five, six ten stable SL, SCN, respectively, were identified at least two individual environments. Five major QPh.cas-5A.3, QPh.cas-6A, QSl.cas-6B.2, QScn.cas-2B.2 QScn.cas-6B explained 5.58-25.68% phenotypic variation. Notably, two, three novel which could provide further insights into factors that shape PH morphology wheat. Conditional analysis revealed mainly affected by SL. Moreover, Kompetitive Allele Specific PCR (KASP) marker tightly linked QPh.cas-5A.3 developed verified using PG-RIL natural population.Twenty-one related identified. These user-friendly KASP8750 will facilitate future studies involving positional cloning marker-assisted selection
