Physiological conceptual framework of measured variables showing the main and pleiotropic effects of the R5A.1 and R5A.2 regions when the allele B19 is present and QGW.perg-6B when the allele B2002 is present. The symbols = indicate not significant effect. The green percentage represents R5A.1 while the blue percentage represents R5A.2 and the red percentage represents QGW.perg-6B. SL: spike length, TS: total spikelets per spike, CN: compactness of the spike, FF: fertile florets per spike, FS: fertile spikelets per spike, FFFS: fertile florets per fertile spikelet, SDW: spike dry weight at anthesis, FFE: fertile floret efficiency, GN: grain number per spike, GW: grain weight, GST: grain set, YLD: yield
