The paper proposes sparse testcrossing with 3-5 testers to improve genetic gain in maize hybrid breeding by balancing simplicity, resource efficiency, and GCA prediction accuracy.

This paper shows that early-stage sparse testing strategies increase genetic gain in plant breeding by improving selection accuracy and intensity through broader TPE sampling and reduced replication.

This study improves genomic selection in hexaploid wheat by incorporating additive and epistatic effects, leading to a 3% increase in prediction accuracy for grain yield.
