G×E Analysis of Early Growth Traits of Populus deltoides in East China by Using BLUP-GGE

In temperate and subtropical climates, Populus deltoides is an important poplar species. To analyze the stability, adaptability, high yield of P. hybrid genotypes in East China, 38 were screened at three experimental sites Shandong Province, coefficients variation genetic characteristics 5-year growth examined using BLUP-GGE. Results showed that all variance higher for diameter breast height (DBH) than tree sites; repeatability heritability greater those DBH sites. The fitting degree was 93.72% 92.22%, respectively. optimum genotype varied by location grouping, which Shanxian County divisions are most powerful representative 5-year-old highly because hereditary factors. more appropriate site tested China. 16, 5, 21, 7 regarded as superior. 8, 26, 36 better Rizhao; 21 Shanxian; 22, 5 Boxing.
