杏核仁主要性状变异及概率分级

Variation and Probability Grading of Main Traits of Armeniaca vulgaris Lam.

杏核仁含有丰富的变异性状,对核仁主要性状进行合理分级可以在数量化和规范化的基础上对杏种质资源进行评价,建立更为具体精确的评价标准是杏种质开发利用的基础。该研究选取22个杏种质,测定核仁主要性状指标并对其变异和概率分级进行分析。结果表明:杏核仁主要性状的变异较为丰富,在8.02%~69.59%,各个主要性状指标间变化规律不一致;杏核仁主要性状Sig.值均处于0.16~1.00,所有主要性状指标均符合正态分布。通过对杏核仁主要性状的分析,提出了基于杏核仁主要性状分布特征的杏种质资源概率分级指标体系,将杏品种依据各性状指标分为3级,并指出各级质量指标范围,使用这一标准可以将杏种质区分出来。不仅可以补充和完善杏分类和鉴定的评价标准,还可以为其它植物种质资源评价中观测数据的规范化和标准化处理提供参考。

The main characteristics of 22 apricot cultivars′kernel were determined,and their variation and probability grading were analyzed.The results showed that the variation of main characteristics of apricot kernel was abundant.The variation rules of the main characteristics were inconsistent,between8.02% and 69.59%.The Sig.values of main characteristics were 0.16 to 1.00,and all the main characteristics were in normal distribution.Based on the distribution characteristics of main characteristics of apricot kernel,the index system of probability classification of apricot germplasm resources was put forward.The apricot varieties were divided into 3 grades according to their characteristics,and got the range of indicators at all levels,so this standard could distinguish the apricot germplasm.The results could not only supplement and perfect the evaluation standard of apricot classification and identification,but also provided reference for the standardization and standardization of the data in the evaluation of other plant germplasm resources.
