A field experiment was conducted during the winter season of 201011 and 201112 at Gwalior, Madhya Pradesh, to evaluate performance of different cultivars of wheat [ Triticum aestivum (L.) emend. Fiori & Paol.] under restricted irrigations on alluvial soils. The treatments were 18 combinations of 3 irrigation levels (no irrigation, 1 irri- gation and 2 irrigations) and 6 wheat genotypes (HI 1572, HI 1500, Lok 1, MP 3288, A 9-30-1 and HI 8627). A significant increase was observed in chlorophyll content index, root-development parameters (length, volume and diameter), yield attributes and grain yield in all the varieties with first irrigation. The increase in these charac- ters owing to second irrigation was also significant, but the magnitude was relatively low. Among the different genotypes, HI 1572 responded more to irrigation than the others and it was closely followed by MP 3288. Signifi- cant decrease in the water-use efficiency was recorded with the increase in water application and highest water- use efficiency was recorded in variety HI 1572, which was closely followed by MP 3288.References
