摘  要：
红麻株高、茎粗是两个最重要的动态发育的经济性状.发育遗传学已探明生物个体的不同发育阶段基因是按一定的时空秩序有选择地表达的.采用数量性状的加性显性遗传模型和发育遗传模型,分析了红麻株高与茎粗在不同生长发育时期的遗传规律,即估算了株高与茎粗在某一生长发育时间(0→t)或某一特定生长发育时间段(t-1→t)的遗传效应.结果表明,株高在不同生长发育时期的非条件、条件遗传效应两者基本一致,均以显性效应为主,加性效应较弱,但条件遗传效应的分析与实际更为相符;茎粗的非条件、条件遗传效应表现一致,各个生长发育时期均未检测到加性效应,而显性效应均达显著、极显著水平;在各个不同生长发育时期中,株高与茎粗均在7月28日～8月9日(旺长期)、9月2～14日(纤维累积期)之间基因表达较活跃.株高与茎粗相关分析表明,两者在各个生长发育阶段均不存在加性相关,但8月21日之后的各期株高与茎粗之间均为显著或极著显正相关,该时期后进行相关选择比较有效.

摘  要：
By using quantitative traits additive-dominance genetics model and developmental genetics model,this paper analyzed the developmental behaviors of gene expression for Hibiscus cannabinu plant height and stem diameter at its different growth stages.The results showed that at different growth stages,the unconditional and conditional genetics effects of plant height all showed dominance,while the additive effect was weak.No additive effect was found for stem diameter,but dominance effect was significant at each growth stage.Plant height and stem diameter all had active gene expression from July 28 to August 9,and from September 2 to September 14.There was no additive correlation between plant height and stem diameter,but positive dominance correlation was significant after August 21.The unconditional and conditional genetics effects of plant height and stem diameter were not completely the same.According to practice,conditional genetic analysis could indicate the gene expression more truly in the whole growth period.The ecological and genetics variation patterns of Hibiscus cannabinus plant height and stem diameter at different space-time growth stages implied by our research was of significance in Hibiscus cannabinus genetics and breeding in both theory and practice.
