为了给野生山杏资源评价及其新品种选育提供理论依据和实践指导,对内蒙古山杏优良单株的果实变异程度、变异类型、果实性状与产量和出仁率之间的相关性进行了分析。结果表明:在山杏的单果质量、果长、果宽、果之长宽比、果肉厚、果径等果实的数量性状指标中,单果质量的变异最大,其选择潜力也最大;根据单果质量的变异程度可将山杏果实分为6个类型,即小果型、较小果型、中果型、较大果型、大果型、极大果型;根据果长的变异特点可将山杏果分为7个类型,即极短果型、短果型、较短果型、中果型、较长果型、长果型、极长果型;根据果宽的变异程度可将山杏果分为7个类型,即极窄果型、窄果型、较窄果型、中果型、较宽果型、宽果型、极宽果型;根据果之长宽比的变异程度可将山杏果分为6个类型,即宽圆果型、较宽圆果型、中果型、较长圆果型、长圆果型、极长圆果型;根据果肉厚的变异程度可将山杏果分为7个类型,即极薄果肉型、薄果肉型、较薄果肉、中果肉型、较厚果肉型、厚果肉型、极厚果肉型;根据果径长的变异程度可将山杏果分为4个类型,即短果径型、较短果径型、中果径型、较长果径型。相关性分析结果表明,山杏果实各性状指标与产量无显著相关,而单果质量、果长、果宽、果径与山杏出仁率显著相关。主成分分析结果表明,3个主成分的累积贡献率达81.145%,第一主成分主要代表为单果质量、果长、果宽、果肉厚、果径长等遗传性状,第二主成分主要代表为果实的长宽比,第三主成分主要代表为产量和出仁率。 In order to provide theoretical basis and practical guidance for the evaluation of wild apricot resources and selection of new varieties, the correlation between the degree of fruit variation, variation types, fruit traits and yield and kernel rate analysis. The results showed that the variation of single fruit quality was the largest among single fruit quality, fruit length, fruit width, fruit aspect ratio, flesh thickness and fruit diameter. The selection potential was the highest. According to fruit quality Of the degree of variation can be divided into six types of apricot fruit, namely, small fruit, small fruit, medium fruit, large fruit, large fruit, great fruit type; Apricot fruit is divided into seven types, namely very short fruit type, short fruit type, shorter fruit type, medium fruit type, longer fruit type, long fruit type, very long fruit type; Apricot fruit is divided into seven types, namely very narrow fruit type, narrow fruit type, narrower fruit type, medium fruit type, wide fruit type, wide fruit type, very wide fruit type; Degree can be divided into six types of apricot fruit, that is wide-round fruit type, a wide round fruit, fruit type, longer fruit type, long fruit type, very long fruit type; according to the degree of variation of flesh thick Apricot fruit is divided into seven types, namely, very thin pulp type, thin pulp type, thin pulp, medium pulp type, thicker pulp type, thick pulp type, extremely thick pulp type; The degree of variation can be divided into four types of apricot fruit, namely, short fruit diameter type, shorter diameter type, medium diameter type, longer diameter type. Correlation analysis showed that there was no significant correlation between the traits and the yield of the fruit of the apricot fruit, but the fruit quality, fruit length, fruit width, fruit diameter were significantly correlated with the almond yield. The principal component analysis showed that the cumulative contribution rate of the three principal components was 81.145%. The main components of the first principal component were the genetic traits such as fruit quality, fruit length, fruit width, flesh thickness and long fruit diameter. The main representative of the second principal component As the fruit’s aspect ratio, the third principal component is mainly represented by yield and kernel rate.
