- The more rigorous the thinning, the greater the possible genetic gain.
- These characters also caused seed yield of have greater correlation genetic gain (CGS y).
- Compared with the commercial species of loblolly pine, genetic gain in volume is 19.2%.
- Assist breeder in technology activities of corn breeding by working together with the team to deliver the goal of genetic gain each year.
- Under the selection rate of 30%for family, the genetic gain for volume was esti mated t o be 3.1%, with combined selection and 148 selected trees.
- These families were Yunnan ChangningC9, LonglinL12, Guizhou TaijiangJiao2, Guizhou LeishanGe5, Guizhou Jianhe Ang4, Ang9 and Ang10 whose mean specific gravity and genetic gain were 0.3404g/cm3 and 5.08%.
