Abstract

Plant height (PH) and flag leaf (FL) are two crucial agronomic traits for crop yield. A recombinant inbred line (RIL) population from ‘Mian 96-5’ (M96-5) and ‘Guixie 3’ (GX3) was investigated in five environments to study PH and FL characteristics in Chinese southwest wheat. Eight QTLs related to PH were detected on five chromosomes 1D (1), 2D (1), 4B (2), 4D (2), and 5A (2). Of these, Qph.gaas.2D explained phenotypic variance (PVE) of 22.40
