Synopsis Differences in relative water requirement found among eight varieties of oats remained highly significant after removal of variation due to tiller number and heading date. Neither character was closely associated with water use, but heading date was more consistently related than tiller number. Environment affected water requirement considerably, but genotypes maintained their relative ranks in efficiency very well. The data suggest that sufficient genetic variability in water use exists to warrant selection for increased efficiency.
