Abstract:
Abstract:The genetic variation,character correlation and principal component were studied on 28 kinds of C.dactylon germplasm collected from Luoyang city based on twelve traits.The results showed that abundant variation existed in these traits.The widest variation was found in turf height that had a coefficient of variance of 57.02,followed by the vegetative stem height,reproductive stem height,leaf length,internode length,internode diameter,inflorescence length,spikelet number,leaf width,inflorescence branch number,spikelet width and inflorescence length.There were significant correlations among some morphological characters of C.dactylon accessions.The biggest correlation coefficient was between reproductive stem height and turf height，was 0.9201.Four principle elements were obtained,which contribute over 82.97% of variance,especially the height factor (51.84%).
