Genetic Variation in Growth and Branch Division Habit of Chinese Fir Clone

  • Received Date: 1996-06-12
  • The paper analyesed seven traits for height,diameter,second year new height,branch plate counts,branch length,branch thickness,branch angle of 35 clones of Chinese fir in a piece of 4-year-old testing plantation.The result showed:There were extreme significant difference on each trait of the clones,and their repeated ability were high and their variation coeffecient were middle.The genetic correlation coefficient were middle among the major growth trait and other determined traits,except H and thickness of branch.There were strong genetic independence among branch traits.5 quick-growing clones have been selected.As compared with CK about their H、D,the reality gain were 22.85% and 30.49%,the genetic gain were 18.07% and 23.82% respectively.

Abstract: The paper analyesed seven traits for height,diameter,second year new height,branch plate counts,branch length,branch thickness,branch angle of 35 clones of Chinese fir in a piece of 4-year-old testing plantation.The result showed:There were extreme significant difference on each trait of the clones,and their repeated ability were high and their variation coeffecient were middle.The genetic correlation coefficient were middle among the major growth trait and other determined traits,except H and thickness of branch.There were strong genetic independence among branch traits.5 quick-growing clones have been selected.As compared with CK about their H、D,the reality gain were 22.85% and 30.49%,the genetic gain were 18.07% and 23.82% respectively.
