Detection of QTLs for Yield Heterosis in Rice Using a RIL Population and Its Testcross Population

Figure 1

Distribution of the mid-parent heterosis values for the six yield traits. NP, number of panicles per plant; NGP, number of grains per panicle; NSP, number of spikelets per panicle; SF, spikelet fertility; TGW, 1000-grain weight; GY, grain yield per plant.
