Transpiration efficiency (TE, in g biomass kg−1 water transpired) of four pearl millet testcross hybrids [H 77/833-2, ICMB 841-P3 (sensitive), PRLT 2/89-33, 863B-P2 (tolerant)] measured at the vegetative and reproductive stage (Experiments 3 and 4, May 2007), under well-watered (WW) and water stress (WS) conditions, and TE measured across WW and WS treatments

Values are the means (±SE) of six replicate plants per treatment and genotype. Genotypic means followed by the same letter within a treatment are not significantly different. LSD is for treatment differences within each genotype
