通过对12年生的兴安落叶松种子园62个无性系的结实特性调查、研究,初步认为:①不同无性系间,由于遗传基础不同,在结实初期,其结实量就相差很大,达723倍;②同一无性系不同分株间结实量仍差异显著,但也有结实较均衡的无性系存在;③根据方差分析结果估算了无性系单株平均结实量的遗传力为049;④结实株率与结实量之间存在着极显著的正相关关系,而生长量和播种品质同结实量之间相关性较差,均不显著。
Based on the investigation and study of the characteristics of 62 clones of 12-year-old larch seed orchard, it is preliminarily believed that: (1) The clonal differences among different clones due to their different genetic basis are quite different 3 times; ② There was significant difference in the seed setting among different ramets of the same clones, but there were also more stable and balanced clones; ③The heritability of the average seed setting of clones was estimated as 049 according to the result of variance analysis There was an extremely significant positive correlation between the seed set rate and the seed setting rate, while the correlation between the seedling yield and the sowing quality was not significant.
