Which lines to phenotype has largely been decided by habit or by picking those most related to the targets. TSOpt instead designs training sets by exact rank-one updates of the prediction error variance; on 328 IRRI elite rice lines it raised predictive ability over random sampling by 0.097, with a design taking about 0.1 s and running roughly 900 times faster than STPGA. Twenty-five designed lines predicted grain yield as well as about 103 random lines, days to flowering as 76 and plant height as 167; its sparse-testing allocations also beat balanced random allocation when a quarter of line-by-season cells were tested.
