Meanwhile, Tibetan sheep (breeded in Sanjiaocheng of Qinghai, Huangcheng and Gannan of Gansu ), Mincounty Blank Fur sheep and Texel and Poll Dorset were controlled. The results indicated that polymorphism was tested at the loci of Hb, Tf and Es, that erythrocyte protein 1 and 2 were monomorphism. There were a couple of allele and three genotypes at the loci of Hb and Es. There were 10 genotypes at the locus of Tf, which was determined by 5 alleles.

The RAPD was used to study the genetic diversity of 19 KinXin series potato cultivars. The result showed that 52 RAPD bands were amplified using 7 primer, among them 43 bands were polymorphic, and 4~9 bands were amplified in each lane. The RAPD analysis indicated that the genetic distance of 19 potato cultivars was between 0.17~0.72, average value was 0.39. When all of the polymorphic bands were analysed by cluster analysis, 19 potato cultivars were classified into 3 groups. The analysis showed that there existed close sibship among the majority of potato cultivars, and the genetic distance between the minority cultivars and the others is longer, which indicate that the genetic basis of KeXin series potato cultivars is wide.

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.
