Enhanced growth phenotype of MSH1 lines in sorghum.

<p>The transgene and crossing procedure used to derive sorghum populations is indicated. (A) The phenotype of the F₁ progeny derived from crossing Tx430×MSH1-dr. (B) Field grown F₂, F₃ and F₄ sorghum lines show variation in plant architecture and height. (C) Panicles from Tx430 (on left, 66 g, 8 mm stem) versus a larger F₂ individual (on right, 112 g, 11 mm stem), and (D) seed yield after threshing. (E) The MSH1-dr sorghum phenotype under field conditions. (F) Sorghum MSH1 F₂, F₃ and F₄ populations grown in progeny rows in a 2011 field experiment. Wild type inbred Tx430 is indicated. Variation in plant height, flowering time and plant architecture is apparent; all plants shown are non-transgenic and Tx430 genotype.
