Microsatellites and Molecular Breeding: Exploitation of Microsatellite Variability for the Analysis of a Monotonous Genome

摘要: Molecular markers and especially those based on selectively neutral DNA sequence polymorphisms have revolutionized the old art of plant breeding, They facilitate reliable identification clones, breeding lines, hybrids cultivars, allow monitoring introgression alien into cultivated germplasm, estimation genetic diversity in germplasm collections, Further, for nearly every important crop, advanced high-density marker maps are now available that provide a basis marker-assisted selection agronomically useful traits, pyramiding resistance genes, isolation these other genes by map-based cloning, In future, molecular techniques clearly will gain more influence speed up processes considerably (see reviews Tanksley et al, 1995, Winter Kahl 1995).
