高产优质油茶单株的选择研究

摘 要：依据一定的选择标准，以高产优质油茶单株的选择为目的，在祁门县平里、祁红等地开展油茶单株的选择研究。经过2007-2009三年连续选择，并对选择单株产量、品质等性状进行观测分析。结果表明：07、08年选42#、51#、55# 三个单株连续两年鲜果实测产量平均为1.87 kg/m2、1.10 kg/m2、2.25 kg/m2，折成油产量分别0.14 kg/m2、0.09 kg/m2、0.15 kg/m2，且品质表现较好。09年选62# 干仁油率达60.11%，鲜果油率11.76%，表现出较高的产量性状。42#、51#、55# 三个单株决选；56#、61#、62#三个单株待选。

The Research on Selecting Single-plant of Camellia oleifera with High Yield and High Quality

According to any criteria,for the purpose of high yield and high quality,single plant ofCamellia oleifera were selected in Pingli and Qihong etc of Qimen county. With continuous selection and analysis on characters of yield and quality from 2007 to 2009,the results showed：the average fresh fruit yield of the single plants 42#,51# and 55# which were selected in 2007 and 2008 for two consecutive years,respectively were 1.87 kg/m2、1.10 kg/m2、2.25 kg/m2. Translated to the average oil yield,they respectively were 0.14 kg/m2,0.09 kg/m2,0.15 kg/m2 and their quality were better. The oil rate of dried seed-kernel of the single plant 62# selected in 2009 reached to 60.11% and its oil rate of fresh fruit was 11.76%. It showed a high yield identity. The single plants 42#,51# and 55# were final selection. The single plants 56#,61# and 62# were to be selected.
