Single Height-Gene Effects in Doubled Haploid Sorghum bicolor (L.) Moench1
- K. F. Schertz2
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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
