From: Identification of Heterotic Loci with Desirable Allelic Interaction to Increase Yield in Rice
Distribution of mid-parent heterosis (MPH) and over-standard heterosis (OSH) for yield-related traits. The MPH and OSH of the yield-related traits were evaluated in 2006 (E1) and 2007 (E2), which are on the left and right of each plot, respectively. The y-axis represents the density (%). The x-axis represents the MPH value (%) and OSH value (%) for each trait. The median of each trait is indicated by the the colored triangle. GN, grain number; PB, number of primary branches; PL, panicle length; PP, panicles per plant; PW, panicle weight; SB, the number of secondary branches; SN, spikelet number; TGW, thousand-grain weight; YD, grain yield per plant
