Restricted Maximum Likelihood Analysis for Yield, Yield Components and Other Agronomic Traits Linear mixed model analysis revealed highly significant ( p ≤ 0.001) differences in plant height, number of total tillers, days to 50% flowering, days to maturity, number of panicles per plant, panicle length, number of filled grains per panicle, one thousand grain weight, and grain yield of screened genotypes under drought stress and irrigated conditions.
