摘要
对在广西三门江林场建立的来自广西各地的175个油茶家系测定林进行了果油率、株产油量等方面的测定,统计分析表明,家系间的果油率、株产油量、公顷产油量均有较大差异,尤其是株产油量差异达极显著水平;以新的油茶优良家系选育主要标准,初步选择出立农106、立农2等8个家系为优良家系,入选率为4.6%;入选家系的果油率、株产油量、公顷产油量3个性状与参试家系比较,选择增益分别达到15.3%、50.6%、87.8%,选择效果良好。
Tests on fruit oil rate and individual plant oil production amount etc. of 175 oil tea families collected from various areas in Guangxi and established in Guangxi Sanmenjiang Forest Farm were carried out. Analysis shows that, big variation of fruit oil rat, individual plant oil production amount, hectare oil production exists amount families, especially that the difference of individual plant oil production amount is extremely obvious. New oil tea superior family selection standard is taken as criteria, eight families such as Linong 106 and Linong 2 are preliminarily selected as superior families, selection rate is 4.6 % . Compared with the tested families, gain of fruit oil rate, individual plant oil production amount, hectare oil production of selected families has increased by 15.3 %, 50.6 % and 87.8 %, respectively. Selection effects are proved to be sound.
