    摘要:

    云南栘［木衣］是云南省的著名野生果树，其果实营养丰富，是理想的绿色水果，由于其果实中富含单宁、粗纤维和黄酮类化合物，导致大多数果实口感酸涩难以直接食用。课题组在前期资源调查过程发现云南栘［木衣］果实自然变异丰富，部分个体的果实汁甜肉脆口感较好，受到大众的喜爱，因此本研究期望筛选出鲜食型优树。本研究以云南省澜沧县糯扎渡镇的100株鲜食型候选单株为研究对象，对其果实表型（单果重、果实横径、果实纵径）进行测定分析，以平均果重（61.28 g）为指标，共筛选出66株初选优株；在此基础上，对初选优株的品质性状（总糖、总酸、维生素C、黄酮、单宁、粗蛋白、粗纤维）进行测定及分析。结果表明，各性状均存在一定变异，其中维生素C含量变异最大，变异系数为0.318，总糖含量最为稳定，总体一致性较高，变异系数为0.064；相关性分析结果表明，除粗蛋白含量与黄酮含量呈显著负相关，其余指标间呈正或负相关，且均未达到显著水平。采用综合评分法对初选优株进行打分并排名，排名越高说明其综合品质越好，最终根据单样本平均数假设检验确定显著低于平均分数的下限值，最终筛选出总得分高于最低下限值（56.13）的13株鲜食型优良个体，其中综合排名第一的为98号，得分66，综合表现最好，其余优株按照综合评分从高到低依次为：1、15、34、12、76、9、77、8、71、7、99、6号。本研究共筛选出了13个优良单株，为鲜食型云南栘［木衣］良种选育提供了宝贵材料。

    Abstract:

    Docynia delavayi （Franch.） Schneid. is a well-known wild fruit tree in Yunnan Province， whose fruit is rich in nutrients and ideal green fruit. The fruit is rich in tannins， crude fibres and flavonoids， resulting in most of the fruit being sour and difficult to eat fruits directly. The preliminary resource survey of Docynia delavayi （Franch.） Schneid. revealed abundant natural variations on fruit. For example， some of them showed a better taste of sweet juice and crispy flesh. Therefore， this study attempted to screen out the fresh Docynia delavayi. In this study， 100 fresh-feeding plants from Nuozadu Township， Lancang County， Yunnan Province， China， were analyzed for their fruit phenotypes （fruit weight， fruit cross diameter and fruit longitudinal diameter）. Based on the average fruit weight of 61.28 g as cutoff， 66 plus plants were obtained， followed by quantifying the quality traits， such as total sugars， total acids， Vc， flavonoids， tannins， crude protein， and crude fibre. There were phenotypic variations at all traits， among which the content of Vc was the most variable with a coefficient of variation of 0.318， and the content of total sugar was the most stable with a high overall consistency with a coefficient of variation of 0.064. Based on the correlation analysis， except for crude protein content that was significantly negatively correlated with flavonoid content， the other indicators were detected with positive or negative correlations without significance. The comprehensive scoring method was used to score and rank the initial selection of superior plants （the higher ranking with better overall quality）， and finally the lower limit of significantly lower than average scores was determined according to the one-sample mean hypothesis test. Thirteen fresh-feeding individuals with a total score higher than the lowest lower limit （56.13） were identified， of which the first one was No. 98 with a score of 66 and the best overall performance， and the rest of the plus trees are， in descending order of overall score： 1， 15， 34， 12， 76， 9， 77， 8， 71， 7， 99， 6. Collectively， this study obtained 13 plus trees of Docynia delavayi， thus providing raw material for the future breeding of improved varieties of fresh Docynia delavayi.
