Agronomic comparisons among wheat lines nearly isogenic for three reduced-height genes

Agronomic comparisons among wheat lines nearly isogenic for three reduced-height genes

Crop Science 26(4): 707-710

The recurrent parent Burt and 5 near-isogenic lines carrying different combinations of Rht1, Rht2 and Rht3 were grown in 21 tests at 4 sites over 8 years and scored for height, yield/ha and 4 yield-related traits. Plant heights of lines with either Rht1 or Rht2 alone, Rht1 and Rht2 combined (2 lines) or Rht3 were reduced by 24, 52 and 64%, respectively, with respect to Burt. All Rht genes reduced volume weight. Rht3 had negative effects on yield, volume weight, grain weight and tiller number.
