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.
