Drought Tolerance in Upland Cotton: Key Findings and Future Prospects

Summary:
A groundbreaking study by Aydin Adnan Menderes University in Turkey has identified eight promising cotton lines that show enhanced drought tolerance. Conducted on upland cotton (Gossypium hirsutum L.), the research focused on key fiber traits such as fiber length, boll weight, fiber strength, and lint percentage under both well-watered and deficit irrigation conditions. Using advanced analytical methods like Principal Component Analysis (PCA) and decision tree techniques, the study pinpointed these traits as crucial for selecting drought-resistant cotton varieties. The findings are significant for agriculture, offering a pathway to maintain cotton productivity amid rising global temperatures and increasing drought frequency due to climate change. The research not only addresses a critical agricultural challenge but also integrates modern biotechnological tools to enhance future breeding programs.
