| 摘 要： | 对采自4省11种源区的341个油松家系种子进行了苗期试验,结果表明：油松种源间以及种源内家系间苗高生长呈极显著的差异,山西浑源种源苗高生长量最大为9.24 cm,内蒙种源苗高生长量小。千粒重与大多数家系苗高相关紧密。油松苗高性状的家系和单株遗传力均大于0.8,呈强度遗传。在不同种源内进行家系选择,预期遗传增益均大于17%以上,增产效果显著。

| Abstract: | Pinus tabuleaformis seeds collected from 4 provinces covering 11 provenances and 341 families was germinated.The results showed that there were very significant differences of seedling height among provenances and families.The seedling height of Shanxi provenance was was 9.24 cm,highest among them,whereas seedling height of Neimenggu provenance was the smallest.1 000-seeds weight was in close correlations with seedling height of the majority of families.The family and single tree heritability in height cont... |
