【Abstract】 The genetic structure and genetic differentiation of Lilium formolongi lines of inbreeding early generations were studied by allozyme electrophoresis. The results of F statistics showed that both homozygosity of lines and differentiation among lines were increased by self cross and selection. The value of F IT of F 4 (=0.72)was higher than that of F 3(=0.392). The value of F ST of F 4(=0.706)was higher than that of F 3 (=0.467). The mean distances among F 4 lines were higher than that of F 3 lines,serving as another evidence to prove the differentiation among lines.更多还原
