Function of Genetic Material: Genes Involved in Quantitative and Qualitative Resistance

  • Thomas Lübberstedt

Part of the Progress in Botany book series (BOTANY, volume 63)


A higher plant contains a minimum of 20,000 genes (Kaul et al. 2000). A successful new variety — the end product of the function of genetic material — is never the result of the addition of just one gene but rather a better combination of several genes. Thus, the challenge in plant breeding is the optimal combination of many genes. Good luck and the “green thumb” of the breeder, are still important prerequisites for successful plant breeding. The question is whether increased knowledge of the function of genetic material will help in offering reliable tools for optimal combinations of the [(n+1) · n]k alleles (n=number of alleles per k loci) in a better genome (Rommens and Kishore 2000).
