The sampled desired gain (d), final index (b), user-specified targeted selection response (dg), and number of standard deviations for the genetic gain of the selected lines [NoIteration, using the standard desired gain index method of Yamada et al. (1975), our method with the reference, Ref, and candidate, Cand, populations] using INDEX2 (yield dominant). Lr, leaf rust; Sr, stem rust; Yr, yellow rust; Prot, protein content; Screen, screening percentage; TKW, thousand kernel weight; and YLD, grain yield; SD Ref, standard deviation reference population; and SD Cand, standard deviation selection candidates.
