Fig. 4From: Effectiveness of spatial analysis in Cryptomeria japonica D. Don (sugi) forward selection revealed by validation using progeny and clonal testsThe relationship between individual tree breeding values of height (in meters) at selection stage and breeding values of height (in meters) for forward-selected individual trees by the progeny test site for the RCB and the AR. n = 28. The correlation coefficients were 0.386 (ns) and 0.628 (p < 0.001) for RCB and AR, respectively. Line is a regression line and the gray area indicates the 95% confidence intervalBack to article page
