Abstract

Numerous ecological factors, including drought, extreme temperatures, too much salt, parasitic diseases and insect pest infestation, endanger sustainable vegetable production. Future vegetable production in many nations may be negatively impacted by these difficult environmental factors. In modernized agriculture, conventional crop-breeding techniques are insufficient on their own to sustainably supply the rising population's food need. The advancement of molecular genetics and associated technologies is a promising method for selecting new crop species. Gene pyramiding using marker-assisted selection (MAS) and other strategies have been applied to produce resilient/tolerant lines with high precision and rapid growth for agricultural sustainability. Gene stacking has not been used to its full potential in the majority of the major farmed crops for the development of biotic stress tolerance and quality enhancement. The focus of this review is on gene pyramiding techniques that are successfully used in contemporary agriculture to increase crop tolerance to abiotic and biotic stresses for long-term crop improvement. Overall, gene pyramiding has the potential to revolutionize vegetable production by enhancing crop quality, productivity and sustainability.

Conclusion

A key technique for crop improvement is gene pyramiding. In order to have a reasonable chance of obtaining the desired genotype, breeders must take into account the minimum population size that must be evaluated when using pyramiding. By lowering the number of generations that breeders must test to make sure they have the desired gene combination, molecular marker genotyping can speed up the gene pyramiding process.
