QPH_1.01, a dominant QTL that contributes to plant height and ear height in maize.

ABSTRACT: Plant height (PH) is an important agronomic trait closely related to yield and lodging resistance. In this study, bulked segregant analysis coupled with next-generation sequencing (BSA-seq) approach was employed to identify quantitative trait loci (QTLs) for PH in a large F₂ population generated from a cross between the tall maize (Zea mays L.) inbred line PH6WC and the short maize inbred line KA3321. Extreme high- and low-PH bulks were constructed by selecting 62 individuals each from the tails of the phenotypic distribution in the 617-member F₂ population.  BSA-seq revealed four PH QTLs, two of which were validated in a random F₂ population. qPH_1.01, a novel QTL on chromosome 1, showed dominance effect for reducing both PH and ear height (EH).
