Ten Pennisetum americanum genotypes differing in plant morphology were grown under both irrigated and nonirrigated treatments in Kansas, USA, and leaf temperature, canopy temperature (Tc), canopy minus air temperature (Tc - Ta), leaf water potential, leaf diffusion resistance, water use and grain yield were evaluated. Significant differences were found between genotypes for grain yield, Tc and Tc - Ta only in the irrigated treatment. From correlation studies it is suggested that average afternoon Tc and Tc - Ta as observed in a nonstressed environment can effectively be used as a technique to screen genotypes for grain yield and grain yield stability (nonirrigated grain yield : irrigated grain yield)
