Introduction, Domestication and Comprehensive Evaluation on Heredity Effects of Pinus sylvestris
[Objective] The growth rhythm and heredity effects of Pinus sylvestris were evaluated.[Method] The progeny from natural populations of Pinus sylvestris were employed to analyze and evaluate the growth rhythm,the heredity variance,the ecological adaptability,the heritability,genetic gain and heterosis on the heredity effects.[Result] Pinus sylvestris had stronger ecological adaptability and coupling,and it can easily adapt to the new ecological environment,the coefficients of variance of seedling height (20.81%) were smaller,but its current increment of height (22.36%) were larger among families.Meanwhile its growth character had strong heritability,high genetic gain,and remarkable heredity effects.The heritability of seedling height,the increment of height in 2013 years,and current increment of height were O.999,O.984 and 0.993,and the genetic gain were16.64%,19.57% and 17.76%.[Conclusion] It recommended model NGF for outstanding group which has extensive application value.The genetic differentiation between groups within the family was small with high genetic gain and large growth potential.
