Abstract:
The advancement of molecular genetics and related technologies such as marker assisted selection has resulted in the establishment of a new discipline in plant breeding known as gene pyramiding. Pyramiding is the stacking of various genes that leads in the simultaneous expression of more than one gene in a variety to promote long-lasting resistance expression. Pathogens cause significant crop loss, thus specific genes from various crops are incorporated to develop resistance against these disease causing pathogens. Pyramiding of genes is critical for broad spectrum resistance to diseases and ensuring disease resistance durability. The feasibility of gene pyramiding is dependent on several essential criteria, including the number of genes to be transferred, the distance between the target genes and flanking markers, the number of genotypes chosen in each breeding generation, the germplasm's nature. The gene pyramiding strategy is clearly efficient in increasing the genetic basis of resistance, and it may be used successfully in combination with all other management strategies.
