Abstract:
With native Chinese hawthorn 83 resources as test materials,the number of the seed and heart chamber,the weight of hundred seeds,the kernel percentage,the trait of the seed in the department of the seed and the fruit traitsincluding the edible percentage and the weight of single fruit were investigated,the correlationship among these traits and the genetic diversity were analyzed.The results showed that there was positive correlation existed between the seed number and heart chamber number and also the single fruit weight,the correlation between the seed number and kernel percentage was negative correlation,the heart chamber number and the kernel percentage was negative correlation；the heart chamber number and the edible percentage was positive correlation,the heart chamber number and the single fruit weight was positive correlation too；the weight of hundred seeds and the kernel percentage was negative correlation,the weight of hundred seeds and edible percentage was positive correlation,the weight of hundred seeds and the single fruit weight was positive correlation；the kernel percentage and the edible percentage was negative correlation,the kernel percentage and the single weight was negative correlation,the edible percentage and the single fruit weight was positive correlation.The analysis of genetic diversity showed that the kernel percentage had the maximum,the value was 75.60%,and then the variable coefficient of hundred seeds weight was 30.73%,the variable coefficient of seed was 21.52%,the variable coefficient of the number of seed,the heart chamber number and the edible percentage was 9.85%,9.85% and 4.89% respectively.Among the 7 traits investigated,the kernel percentage,hundred seeds weight and the trait of seed had the significant genetic variation,and could be the main traits for the hawthorn classification in the future.
