Kernel weight contribution to yield genetic gain of maize: a global review and US case studies.

Journal of experimental botany - 2 Jun 2022

Abstract excerpt

Over the past century of maize (Zea mays L.) breeding, grain yield progress has been the result of improvements in several other intrinsic physiological and morphological traits. In this study, we describe (i) the contribution of kernel weight (KW) to yield genetic gain across multiple agronomic settings and breeding programs, and (ii) the physiological bases for improvements in KW for US hybrids. A global-scale...
