Abstract: The benefits of developing and releasing salinity-tolerant and phosphorous-deficiency-tolerant rice in Bangladesh, India, Indonesia and the Philippines are estimated for marker-assisted breeding (MAB) and for conventional breeding (CB) using economic surplus analysis. Marker-assisted breeding is estimated to save at least 3-6 years in the breeding cycle and result in incremental economic benefits over 25 years in the range of $50 to $900 million compared to CB, depending on the country, stress, and time lags. Saline and phosphorus-deficient soils are difficult problems to address through CB because of undesirable traits that accompany desirable ones during the breeding process. Marker-assisted breeding, enabled by advances in genomics and molecular mapping is more precise and time-saving. Costs are estimated at $3.4 million for MAB and $2.5 million for CB, and hence the additional net benefits of MAB in rice far exceed those for CB.
