The exogenous total DNA of the wild high-protein soybean was transferred to cultivatedsoybean through the pollen tube channel and the genomic variation of the transformed progeny was detected bythe method of RAPD(Random Amplified Polymorphic DNA).Distinguished variations were found in one of the 7 transformed plants of the first generation(D1),ofwhich the traits of fruition,outward appearance,leaf shape and flower colour were almost identical withthose of the recipient parent;of which grain weight,seed coat colour and stem strength were situated betweenthe two parents;and there were greatly more pods per plant and 12.5% higher content of protein in seedsthan that of the recipient parent.All the properties have been invariably inherited for 3 generations.Through RAPD analysis of the genomes of the donor,the recipient and the transformed progeny(D3)as agroup,DNA polyrnorphisms were found in amplified products by 24 of 150 primers.The results prove thatthe exogenous DNA caused the distinct variance of the genome.The authors infer that the homogeneousrecombination of large exogenous DNA is the main cause for the variance.
