摘要： 为了认识澳洲坚果植株生长量性状的传递遗传规律，以澳洲坚果10个无性系品种为材料，正反交设计，共90个杂交组合，获得90个全同胞家系苗木。并对种子横径、苗木株高、地径及冠幅进行变异分析。结果表明，10个母本间种子横径达显著差异(P<0.05)，同一母本所对应9个父本的组合间种子横径达显著(P<0.05)或极显著(P<0.01)差异，说明种子的大小不仅仅决定于母本，而且也受父本的影响。对苗木株高、地径和冠幅的分析表明，全同胞家系间差异显著(P<0.05)，母本半同胞家系间差异显著(P<0.05)，而父本半同胞家系间差异不显著。苗木生长量受父母本的基因共同决定，但母本影响的变异分量相对较大，父本影响的变异分量相对较小。

Abstract: In order to investigate the transmission heredity of Macadamia sp. plant growth, 10 Macadamia clones were used as materials, 90 cross combinations were obtained with direct crossing and reciprocal crossing, and seedlings of 90 full-sib families were obtained. Variation analysis was carried out in aspects of seed diameters, seedling height, basal diameter and crown width. The results showed that there was significant difference (P<0.05) in the seed diameter from 10 female parents. And also there was significant difference (P<0.05) or extremely significant difference (P<0.01) in the seed diameter from 9 male combinations corresponding to one female parent. This indicated that seed size depended on its female parent, but also was affected by male parent. Variation analysis of the seedling height, basal diameter and crown width showed that there was significant difference among full-sib families and among half-sib progenies family of female parents (P<0.05), while there was no significant difference in that of male parents. Although gene from both parents played a role in the growth of seedlings, variation percentage to be affected by female parent was larger than that from male parents.
