A comparison of short and tall sorghum, Sorghum bicolor (L.) Moench, determined the effects on morphological and agronomic characteristics of a single gene for height. Short doubled haploids, recessive at four major height loci (4‐dwarfs), were compared with tall mutant derivatives, recessive at three loci (3‐dwarfs) and dominant at one locus. The short and tall plants differed in height, internode length, leaf‐blade length, leaf‐sheath length, panicle width, and grain weight. Differences in height and internode length are due to a single gene difference. The other differences are either a direct effect or an indirect effect of this gene.
