摘要：
Wheat plants are most sensitive to soil water conditions after anthesis. Under water stress, genotypic variability in grain set was noted. Drought enhanced maturity, lengthened grain filling duration and adversely affected the number of grains/spike and 100-grain weight of wheat cultivars from the Philippines and Nepal. Grain protein content increased with the increase in drought duration. Siddhartha, NL 292, NL 370, and NL 496 all from Nepal produced the maximum grain yield and also harvest index under stressed conditions.
