Analysis on Ecology Coupling and Evaluation on Heredity Effects of Quantitative Characters from Lonicera edulis

Lonicera edulis prefer the cold and wetter climate,and it is a perennial shrub belonging to wild berry category,which it has a high nutritional and medicinal value. The ecology effects and heredity effects of quantitative characters were analyzed base on discussing the ecological coupling on light,heat,water and soil resource of Lonicera edulis in extremely cold areas. The results showed that there were certain difference on the berry characters among the different habitat types,and the coefficients of variance of the fruit vertical( 9. 38%) were small,but its transect diameter( 11. 92%) were large and its seed numbers( 20. 64%) were the largest. Meanwhile its berry character had medium heritability and genetic gain,and its genetic diversity was smaller. The heritability of fruit vertical,transect diameter and seed numbers were 0. 825, 0. 559 and 0. 627,and the genetic gain were 7. 53%,5. 72% and 11. 94,respectively.
