The College of Agriculture at the University of Kerbala discussed a master’s thesis by student Mohammed Kassed Turki Al-Kuraity, entitled “Response of Yellow Corn Hybrids (Zea mays L.) to Weed Control Using Selected Chemical Herbicides and Study of Herbicide Resistance in Echinochloa colona”, in the presence of faculty members and postgraduate students.
The thesis aimed to:
- Evaluate the efficacy of the herbicides Reef Sulfuran, Trinity, and Proponit in controlling Echinochloa colona (junglerice).
- Study the response of three yellow corn hybrids (Torro, Top, and Tawer) to the herbicides.
- Detect genetic mutations in the ALS and psbA genes associated with herbicide resistance.
The study yielded several important findings, including:
• Full chloroplast genome sequencing of Echinochloa colona L. was recorded in the GeneBank.
• A total of 19 mutations were identified in the ALS gene and 80 mutations in the psbA gene.
• The Torro hybrid outperformed the others in most growth and yield traits.
