From: Sorghum Dw2 Encodes a Protein Kinase Regulator of Stem Internode Length

Additive effects of Dw2 and Dw3 on the length of each internode (BTx623 x IS3620c RIL population). The RIL population was grown in the greenhouse and the length of each internode (numbered from the peduncle) was measured. Additive effects were determined as part of QTL mapping performed in R/qtl using IM. The BTx623 allele of Dw2 increases internode length, whereas the IS3620c allele of Dw3 increases internode length.
