我国果梅品种资源若干果实性状的数量分布及其评价标准探讨

首次对我国(包括台湾)果梅108个品种果实的单果重、可溶性固形物含量、总酸含量、可食率及鲜核重等5个主要品质性状的数量分布进行了分析。结果表明,单果重平均为19.58g±6.24g,集中分布在15.01～20.00g与20.01～25.00g之间;可溶性固形物含量平均为7.44%±1.13%,大多数分布在6.01%～7.00%与7.01%～8.00%的偏低范围内;总酸含量平均为4.74%±0.95%,绝大部分品种资源分布在3.01%～7.00%之间;可食率的平均值为87.97±3.40%,在85%以上的品种数占80.36%;鲜核重平均为2.23g±0.61g,大多数分布在1.51～2.00g和2.01～2.50g之间。首次提出了这些性状的评价标准,从而为果梅资源的研究利用及育种目标的制定提供科学依据。

Study on the Quantitative Distribution of Some Fruit Qualitative Charac ters of Japanese Apricot (Armeniaca mume Sieb.) Cultivars and Their E valuation Criteria

The quantitative distributions of some fruit qualitative characters,including average fruit weight(AFW),soluble solid content(SSC),total acid content(TAC),flesh eatable rate(FER),and flesh pit weight(FPW)of108accessions of Japanese apricot cultivars(Armeniaca mume Sieb.)in China were studied in this paper.The results showed that the average values and the main distributions of each qualitative charcter mentioned above are respectively as follows 19.58g±6.24g/15.01～20.00g and20.01～25.00g(AFW) 7.44%±1.13%/6.01%～7.00and7.01～8.00%(SSC);4.74%±0.95%/3.01%～7.00%(TAC);87.97±3.40%/85%～95%(FER);2.23g±0.61g/1.51～2.00g and2.01～2.50g(FPW).The evalution criteria of these characters were made which will be quite useful for the future study and utilization of Japanese apricot germplasm as well as for the construction of Japanese apricot breeding targets.
