11 份黄晶果种质资源植物学特性及果实品质综合评价

    Comprehensive Evaluation on Botanical Characteristics andFruit Quality of Eleven Abiu Germplasm Resources

    • 摘要: 【目的】明确 11 份黄晶果种质资源的植物学特性和果实品质特性,为黄晶果种质资源鉴定评价以及优良品种培育提供参考依据。【方法】田间观测黄晶果的植物学特性,测定果实的 16 个品质指标,并对其进行相关性分析。【结果】供试黄晶果种质资源在植物学性状和果实品质方面表现出较大差异,表明具有丰富的遗传多样性,果实各指标间具有不同程度的相关性;根据综合分析评价,种质 HJG151 整体树势壮旺,成熟果实浑圆金黄,平均单果重高达 276.47 g,可食率 67.64%,果实内部经济特性优良,整体性状指标基本保持一致;HJG134 维生素 C 和原果胶含量最高,分别达 0.50 mg/g 和 0.98%,可作为部分性状指标优异的备选种质资源。【结论】筛选出优异黄晶果种质两份,为黄晶果种质资源的创新利用以及优良品种的培育提供了良好基础。

       

      Abstract: 【Objective】Botanical characteristics and fruit economic characters of 11 abiu germplasm resources were identified in order to provide a reference basis for the identification and superior variety breeding of abiu germplasm resources.【Method】The botanical characteristics of abiu were observed in the field. 16 quality indexes of the fruits were measured and a correlation analysis was conducted.【Result】The experimental germplasm resources of abiu had great differences in botanical characteristics and fruit economic characters, showing rich genetic diversity and different degrees of correlation among fruit indexes. The comprehensive analysis showed that HJG151 grew vigorously, the shape of mature fruit was perfectly round and the pericarp color was golden, with an average single fruit weight of 276.47 g and an edible rate of 67.64%. The fruit economic characters was superior and the overall character indexes were basically consistent. Vitamin C and protopectin content of HJG134 were the highest, which were 0.50 mg/g and 0.98% respectively. It could be used as an alternative germplasm resource with some excellent character indexes. 【Conclusion】2 excellent germplasms werescreened out, which provides a theoretical basis for the innovative utilization of abiu germplasm resources and the cultivation of excellent varieties.
