Abstract: The isOZyme zymograms and photosynthetic characteristics of 5 pacesetters(hybrids between Sorghum and Sudangrass) and 2 sudangrasses were aNa+lyzed. Based on the results measured by 4 photosythetic indices including net photosynthetic rate,stomatal conductance, intercellular COZ concentration and transpira-tion,the results of comprehensive evaluation of photosynthesis capability of 7 tested plants showed that Mengnong Qingsi No.3 'Mengnong Qingsi No. 1=Mengnong Qingsi No. 7=Jiabao'Black hull sudangrass= White hull sudangrass>Jianbao. 7 tested plant materials were diffent in the number,locus and intensity of proxidase (POD) and superoxide dismutase (SOD) isOZyme bands at tillering stage,which are the important ba-sis for identifying tested plants in protein level;the zymogram phenotypes of a isOZyme are varied with different developing stages and different organs of a plant,to aNa+lyze and compare isOZyme zymograms of tested plant materals at different developing stages and different organs could reflect the genetic differences more accurately to enhance the accuracy of identified result than at only one stage and one organ.

Key words: Sorghum, Sudangrass, Hybrid , Photosynthetic characteristics, IsOZyme zynogram phenotype
