46个麻疯树半同胞家系试验表明,在相同种植管理条件下,不同家系间、家系内的平均树高、冠幅、分枝数、结实量有极显著差异。经多重比较分析可知,家系159,114,119及131号各性状指标均较好,可入选为早期表现优良的家系。以树高和冠幅大于2.0 m、结果数量大于120颗、种子千粒质量大于500 g为标准进行优良单株初选,共选出13株优良单株,可做为进一步无性系测定或育种的材料。
The results of 46 families of J. curcas half-sib families showed that the average tree height, crown width, number of branches and seed-setting among different families and families were significantly different under the same plantation management conditions. After multiple comparative analysis, it can be seen that all the traits of families 159, 114, 119 and 131 are better, and can be selected as early-performing pedigrees. Thirteen elite individuals were selected as excellent primaries based on the tree height and crown width greater than 2.0 m, the number of the results more than 120, and the seed quality of more than 500 g per 1000 seeds as the standard, which could be used for further clonal determination or breeding s material.
