应用外源DNA导入春麦改良主裁品种的某些性状,结果表明:利用花粉管通道进行外源DNA直接导入是改良春麦品种的有效技术.导入D_2代在表现型及基因型均发生变异,变异具有随机性,不受亲缘关系的影响,获得一批优良性状的变异株(系),特别是高蛋白质含量的变异株系,比原品种蛋白质含量提高2—4%.
The results showed that direct introduction of exogenous DNA by pollen tube pathway was an effective technique to improve the spring wheat varieties.D2 generation showed the variation and variation of phenotype and genotype The random mutants (lines) with random characters and unaffected by the genetic relationship obtained a number of excellent traits, especially those with high protein content. The protein content is 2-4% higher than that of the original variety.
