4. Productivity factors, cultivar choice and production ecology
nature of cultivars: single cross hybrids , multi-parent crosses/ OPVs
agro-climate: temperate , tropical/sub-tropical
crop duration: long ,medium, short
inputs: irrigation, fertilization,etc
Production ecology & requirements
Kharif
early maturing (75-85 days )drought tolerant cultivars for rain-fed ecology (80% area)
medium (86-95 days)/Late maturing (>95days) cultivars for high input conditions (20% area)
Rabi
20% maize- growing area
late maturing ( days) cultivars
Spring
early/medium maturing heat tolerant cultivars

5. Hybrid Development in Maize
Focus on Single Cross Hybrids (SCHs) since
Development of stable, vigorous and productive inbred lines with seed yield >3.0t /ha
Evaluation of inbred lines for per se performance, biotic and abiotic stresses and quality
Categorization of lines with respect to Seed and Pollen parent ( heterotic grouping)
Use of desirable lines in the development of productive hybrids
Multi –location testing (under AICRP programme)
