CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
Maize
Maize Hybrid Success Factors
Hybrid varieties, particularly in crops like Maize, leverage a phenomenon called heterosis or hybrid vigor. Heterosis refers to the improved or increased function of biological qualities in a hybrid offspring compared to the individual parent organisms.
Why Maize Excels with Hybrids
- Genetic Basis: Maize is naturally cross-pollinated, making it highly amenable to producing hybrids by crossing distinct inbred parent lines.
- Heterosis Benefits: Hybrid Maize typically exhibits significantly higher yields, increased uniformity, improved disease resistance, and better adaptability to various environmental conditions compared to open-pollinated varieties.
- Commercial Viability: The significant yield advantage and robust performance make hybrid seeds a commercially successful product in Maize cultivation worldwide.
- Controlled Breeding: Unlike self-pollinating crops (like wheat and lentils) or less extensively studied cross-pollinators (like pigeonpea), the breeding technology for consistent, high-performing Maize hybrids is well-established and widely adopted.
Comparative Success
While hybrid technology is applied to other crops like wheat and pigeonpea, its impact and success rate are most pronounced and commercially dominant in Maize due to its biology and the advanced breeding programs developed over decades.
