Conclusion
Weed pressure remains one of the most critical biotic constraints limiting sugarcane
productivity, with specific weed biotypes and their duration of infestation significantly influencing
crop growth and yield attributes. The study demonstrated that certain hybrid genotypes,
particularly BD 1098-001, BD 1098-003, BD 1098-005, and BD 1098-014 exhibited superior
agronomic performance, characterized by high cane yield and elevated estimated recoverable
sucrose (ERS). These genotypes show strong potential for advancement and multi-locational
testing across diverse ecologies to assess yield stability and juice quality consistency.
Clones exhibiting high fiber content alongside good sugar yield may serve dual purposes for both
sugar and ethanol production, an avenue yet to be fully explored in Nigerian sugarcane breeding
programs. Identifying genotypes suited for such dual-purpose use could significantly enhance
the efficiency and profitability of the sugar industry.
The timing of the highest Brix percentage in non-flowering sugarcane genotypes provides a
practical indicator for determining physiological maturity and optimizing harvest schedules. This
physiological insight is critical for improving sugar recovery and reducing post-harvest losses.
The advancement of promising hybrid clones for broader adaptability trials is therefore
imperative. Future breeding efforts should focus on integrating high-yield potential with traits
conferring weed-suppressive ability, stress tolerance, and improved juice quality. Furthermore,
sustained investment in genetic improvement, adaptive breeding, and climate-smart agronomic
management is essential for developing resilient sugarcane varieties capable of maintaining
productivity under increasing climatic variability.
In addition, complementary research on integrated pest, disease, and weed management will be
indispensable for ensuring sustainable cane production and achieving national self-sufficiency
in sugar and bioethanol production.BOOK CHAPTERS 19 OCTOBER 2025 Shittu, E
