Path analysis of the causal relationship between agricultural traits of O. sativa and O. glaberrima under Korean climate conditions. Path analysis of 1000-grain weight in O. sativa (A) and O. glaberrima (B) and path analysis of yield-related traits in O. sativa (C) and O. glaberrima (D). Arrows in a single direction indicate linear dependencies calculated with standardized regression coefficients, and double-headed dotted arrows indicate correlation coefficients between each characteristic. Green and red represent positive and negative effects, respectively. NT: number of tillers, NS: number of spikelets, RRG: ratio of ripened grain, TGW: 1000-grain weight, YIE: yield, GL: grain length, GW: grain width, GT: grain thickness.
