摘  要：
以9个授粉品种对5个长山核桃无性系进行人工授粉,探讨不同授粉品种对长山核桃坐果率及果实性状的影响。结果表明,5个无性系的父本方差贡献率均高于5 0%,同一母本下,不同父本的杂交组合之间坐果差异都达到了极显著水平。父、母本之间表现出交互作用,除核果质量的父本间差异不显著,其余性状各差异均达到极显著水平;4 5个杂交组合内7个性状指标的变异幅度很大,变异系数最大的是无性系2 1号单果质量,达到2 6.3 3%,最小的是无性系1 3号核果径,为1.5 3%;根据各杂交组合单株间坐果及果实性状的差异情况,为5个母本筛选了适合的父本作为与其配置的授粉品种,如3 5号和建林1号可为无性系1 0 4授粉,1号、3 4号和建林1号可为无性系2 8号授粉,5号和1 2 7号可为无性系2 1号授粉,3 4号和6号可为无性系1 3号授粉,以及3 5号、5 2号和建林1号可为无性系1 1号授粉。

摘  要：
The effects of different pollen sources on pecan nut setting and development were studied by testing 9 pollinating varieties on 5 pecan clones.The results showed that the male variance contribution rate of all5 clones were higher than 50%.Pollination with different varieties significantly affected the nut setting of individual females.The interaction between parents was observed.All nut characters except nut weight between male parents had a highly significant deviation.There was a large variation among the 7 nut characters across all45 crossings.The largest coefficient variation reached to 26.33%that was observed for the nut weight of the 21~(th)clone,while the smallest one was 1.53%with the nut diameter of the 13~(th) clone.We selected suitable pollination cultivars for the 5 females based on the nut setting and other characters of each of 5 individual clones.For example,the 35~(th) clone and Janlin No.1 could be the pollen source for the 104~(th) clone;the 1~(st) clone,the 34~(th),and Janlin No.1 could be male plants for the 28~(th) clone;the 5~(th) and 127~(th) clones for the 21~(th);the 34~(th) and 6~(th) clones for the 13~(th);the 35~(th) and 52~(th) and Jianlin No.l clones for the 11~(th) as pollinating plants.
