Relative incremental benefits for breeding programs (βRGA,n) with varying length of variety development time (b) based on Eq (17).
Note: r = 2 and i = 0.05.

Relative incremental benefits for breeding programs (βRGA,n) with varying time savings (r) based on Eq (17).
Note: i = 0.05 and b = 13.
Table 3.
Meta-analysis of incremental societal benefits attributed to various research organisations (ΔBRGA) for a discount rate (i) ranging from 3 to 5% and a two-year reduction (r) of the breeding process due to the adoption of RGA in rice breeding (in million US$).

Characteristics of estimated research and incremental benefit functions.
Fig 5.
Line plot of relative research benefits for conventional breeding method (upper panel) and incremental benefits (lower panel) for a two-year reduction (r) for a meaningful range of discount rates (i) for selected breeding studies.
Note: To enable comparison between different studies, the ratio of (discounted) research (BCM) and incremental benefits (BRGA) to undiscounted research benefits were taken for every value of the discount rate (relative benefits). Different lines represent different breeding projects reported within the same study.
