| Description |
Near Isogenic Introgressed Lines (NIILs) of IR 64 x Binam (IB) and Teqing x Binam (TB) were evaluated under non-stress (E1), moisture stress at vegetative stage (E2) and reproductive stage (E3) for identification of QTLs for physiological and productivity traits. High yielding NIILs were superior for productivity traits like, number of panicles per plant, panicle weight, number of grains per panicle, spikelet fertility and also for physiological traits like photosynthetic rate, relative water content (RWC) and chlorophyll meter (SPAD) reading under stress indicating their importance for drought tolerance. In all, 61 QTLs in IB NIILs and 35 QTLs in TB NIILs were detected (P |
