Drought Yield QTL () with Consistent Effects on Morphological and Agronomical Traits of Two Populations of New Rice () Lines.

Drought has been a major limiting factor for rice production. Drought yield QTLs ( quantitative trait loci) were pyramided into MRQ74 and MR219 to produce drought tolerant lines. In this study, new drought tolerant MRQ74 and MR219 pyramided lines (PLs) were evaluated under drought stress (RS) and non-stress (NS) conditions to evaluate the effects of different combinations on morphological and agronomical traits.
