From traditional selection to selection by means of DNA-markers

Quantitative attributes have a complex hereditary basis, are controlled by a great number of genes and are substantially subject to modifying influence of environment. Application of mo-lecular markers opens wide prospects for studying the genetic nature of quantitative attributes by locus marking, that define their development, and on this basis practical increase of effi-ciency the selection methods. The RAPD-analysis of corn lines by KBSU selection with the use short primers in the length of 10 nucleotides is spent.
