摘　　要：于2019年,在云南省林业和草原科学院普文试验林场后山,对4个种源(勐旺、西盟勐梭、大渡岗、普文)35个家系的16年生云南红豆试验林生长性状和遗传参数进行分析。结果表明:树高、胸径和单株材积在种源家系间的差异达到极显著水平。普文种源中,P_(2)平均胸径为18.3 cm,平均单株材积0.199407 m^(3),胸径、单株材积遗传增益分别达27.69%、75.29%;P_(7)平均树高16.8 m,树高遗传增益达24.15%;P_(10)树高、胸径、单株材积遗传增益分别达到22.71%、21.87%、72.45%。初步认定普文种源中P_(2)、P_(7)、P_(10)为普文试验林场(热区)适宜种植家系。The growth traits and genetic parameters of 16-year-old Ormosia yunnanensis experimental forest with 35 families from 4 provenances were analyzed in Puwen Farm,Yunnan Academy of Forestry and Grassland in 2019.The results showed that there were extremely significant differences in tree height,DBH and individual volume among provenances and families.The average diameter at breast height of P_(2)is 18.3 cm,and the average individual volume is 0.199407 m^(3).The genetic gains of DBH and individual volume were 27.69%and 75.29%respectively.The average tree height of P_(7)is 16.8 m,and the genetic gain of tree height is 24.15%.The genetic gain of P_(10)tree height reached 22.71%,the genetic gain of DBH reached 21.87%,and the genetic gain of single plant volume reached 72.45%.P_(2),P_(7)and P_(10)among the provenances of Puwen were identified as the most suitable families for planting in the Puwen experimental forest farm(hot area).
