Abstract:

Fifteen F1s for 6 maize inbreds with variable reactions to moisture stress (susceptible, Ib1, Ib2 and Ib4; and tolerant, Ib3, Ib5 and Ib6) were analysed for stability under different moisture regimes and locations. In kharif 2000 in Delhi, India, moisture stress trials were conducted under rainfed conditions (approximately 155 mm during the crop period). In Hyderabad (Andhra Pradesh) during rabi 2001, moisture stress was conducted by withholding irrigation during flowering and post flowering stages. The parameters tested included days to 50% silking, anthesis-silking interval, plant height, grain number/row, test weight and grain yield/plant. Ib3 × Ib4 appeared to be stable for days to silking, while Ib2 × Ib6 performed stably for plant height and Ib5 × Ib6 for plant height. Ib5 × Ib6 appeared to be suited to rich environments. Ib5 × Ib6, Ib3 × Ib6 and Ib3 × Ib5 were stable for grain number/row. Ib2 × Ib5 and Ib3 × Ib5 were stable for 100-seed weight. Ib5 × Ib6 and Ib2 × Ib3 were stable for grain yield/plant.
