Abstract:

Maize grain yield is closely associated with kernel number at maturity, and kernel number is affected by apical kernel abortion mainly occurred at early kernel filling stage. Improving apical kernel development and reducing apical kernel abortion can contribute to increment of kernels per ear. Th
