Abstract excerpt

Kernel rate (KR), the ratio of kernel to ear weight, serves as a key metric of assimilate partitioning efficiency and determines single-ear yield stability under high planting densities. Despite its critical role in modern intensive agriculture, the genetic architecture of KR remains largely elusive. Here, we performed a genome-wide association study (GWAS) for KR and its component traits-ear weight (EW), kernel...
