摘要
为了丰富我国日本落叶松育种资源,改善育种状况,提高育种水平,有必要选育适合在中北亚热带高山区栽植日本落叶松优良品种。在湖北省建始县开展了日本落叶松种源试验研究,从中选择出来了3个优良家系。127号家系14a生胸径、树高、材积分别为18.07 cm、13.65 m、0.167 9 m3,分别高出对照217号家系的19.5%、21.9%、74.1%;92号家系14a生胸径、树高、材积分别为17.94 cm、13.26 m、0.160 8 m3,分别高出对照217号家系的18.7%、18.4%、66.7%;121号家系14a生胸径、树高、材积分别为17.94 cm、13m、0.1577m3,分别高出对照217号家系的18.7%、16.1%、63.4%。
In order to enrich our country Japanese larch breeding resources,improve breeding situation,and raising breeding level,it is necessary to？select fine cultivated varieties of Larix kaempferi that are suitable for planting in north subtropical high mountainous area.The provenance trial of Larix kaempferi has been carried out Jianshi county,Hubei province.Three superior families（No.127,No.92 and No.121） were？filtered out.Of them,No.127 family＇s（14-year-old） DBH,tree height,volume were 18.07 cm,13.65 m,0.1679 m3 respectively,they were higher than corresponding values of No.217 family＇s by 19.5%,21.9%,74.1%;92,respectively;No.92 family＇s（14-year-old） DBH,tree height,volume were 17.94 cm,13.26 m,0.1608 m3,they were higher than corresponding values of No.217 family＇s by 18.7%,18.4%,66.7%;No.121 family＇s（14-year-old） DBH,tree height,volume were 17.94cm,13 m,0.1577 m3 they were higher than corresponding values of No.217 family＇s by 18.7%,16.1%,63.4%.
