| 摘 要： | 通过对4.5年生火力楠种子园自由授粉家系子代测定林生长性状的调查研究,在生长差异比较基础上判定家系优劣,估算遗传参数与遗传增益。结果表明:种子园子代林树高、胸径、材积3个性状生长量明显大于对照。参试家系间也存在着较为丰富的变异,具有选育潜力。通过差异显著比较入选的2个优良家系平均遗传增益分别是13.25%、28.03%7、6.65%,其可作为营建火力楠改良代种子园材料,亦可作为优良材料进行推广应用。

| Abstract: | Based on the investigation of the growth characters in a 4.5-year-old open-pollinated Michelia macclurei progeny testing stand,the comparison and variation analysis were applied to determine the family quality and to estimate genetic parameters and genetic gains.The results showed that the height,DBH and volume growth of the progeny test plantation were significantly higher than that of the control,and there were relatively high variations among tested families which possessed breeding potential.According t... |
