Correlation coefficients between the presence of theRht-B1p,Vrn-B1a, andPpd-D1aalleles in homozygotes and valuable agronomic traits in families F_3:4Chris Mutant/Novosibirskaya 67 in field tests in Moscow (violet line) and Krasnodar (green line). Blue and red represent negative and positive correlations respectively. PH, plant height; IN, internode number; PL, peduncle length; MSL, main spike length; SN, spikelet number; SC, spike compactness; MSW, main spike weight; MCW, main culm weight; MSB, main shoot biomass; GW, grain weight per main spike; GN, grain number per main spike; GNS, grain number per spikelet; W, thousand grain weight; HI, harvest index; H, heading date; SAT, sum of active (> 10 °C) temperatures to heading date; SAD, sum of active (> 12 h) light days to heading date
