Area of Science:

  • Plant genetics
  • Agronomy
  • Crop science

Background:

  • Maize (Zea mays) is a vital global crop susceptible to yield losses from stalk lodging.
  • Rind penetrometer resistance (RPR) is a key indicator of stalk strength and lodging resistance.
  • Genetic dissection of RPR is essential for developing lodging-resistant maize varieties.

Purpose of the Study:

  • To investigate the genetic basis of rind penetrometer resistance (RPR) in maize.
  • To identify quantitative trait loci (QTL) and candidate genes influencing stalk strength.
  • To evaluate the efficacy of genomic selection (GS) for improving RPR.

Main Methods:

  • Utilized two recombinant inbred line (RIL) populations for genetic analysis.
  • Evaluated RPR across seven distinct growth stages.
  • Employed linkage mapping and genomic selection (GS) models.

Main Results:

  • Identified 66 and 45 QTL for RPR in the two RIL populations, respectively.
  • Optimal RPR measurement stages identified as silking and post-silking.
  • Candidate genes involved in cell wall biosynthesis were associated with RPR.
  • Multivariate GS models significantly improved prediction accuracy for RPR.

Conclusions:

  • Maize RPR is controlled by a complex genetic architecture involving multiple minor-effect QTL.
  • Pleiotropic QTL identified across multiple growth stages offer potential for developing functional markers.
  • Genomic selection presents a promising strategy to accelerate breeding for enhanced stalk strength and lodging resistance in maize.
