The inheritance of drought resistance and agronomic characteristics of field-grown sorghum plants was determined. High heritabilities were recorded for each characteristic. The genetic differences of percentage moisture loss were due to genes exhibiting incomplete dominance. The agronomic characteristics of plant height, peduncle length, days to 50% flowering and yield potential all provided evidence of dominant genetic variation. A few parental inbred lines that could be used to improve drought resistance of commercial hybrids have been identified. Results indicated that the percentage moisture loss of excised leaves of mature plants could be used as a selection criterion for drought resistance in sorghum.
