Abstract:
Using ‘Jade plate’‘Flap Hydrangea’ and ‘Luminous cup’and other 30 varieties of Paeonia rockii as experimental materials,nine characteristics were chosen as evaluation factors，by using the grey correlation analysis，the influence of varieties of Paeonia rockii traits on the overall performance of the varieties were studied，evaluation of varieties were comprehensived，in order to screen out suitable Paeonia rockii varieties for Luoyang region growth and had good ornamental，to explore scientific peony cultivars comprehensive evaluation system，provided a reference for peony breeding and extension of new varieties.The results showed that among the 30 varieties of Paeonia papaveracea，there were 20 varieties and reference variety weightrelation larger(r>0618 6)，had a good adaptability and ornamental.Among them，‘Zihai silverwave’ with the weighted correlation degree of the reference variety was the largest(r=0812 2)，comprehensive characters was the best，the second was ‘Red Hydrangea’(r=0748 8) and ‘Luminous cup’(r=0729 6)，and the ‘Light capacitance’ connection was the least(r=0531 7).The evaluation results were consistent with the actual performance of the varieties.Using grey relational analysis method was scientific and feasible evaluation of Paeonia papaveracea.
