摘要: Near-isogenic tall (no dwarfing gene), semidwarf (Rht1 or Rht2) and dwarf + Rht2 Rht3) spring wheat lines were evaluated for yield components under irrigated rainfed conditions. Under conditions, the exhibited a significant advantage over lines. outyielded as well Percent reduction in response to drought stress was highest with dwarfs lowest Dry matter production of that did not differ significantly both produced more dry than Plant height kernel weight decreased increasing degree dwarfness while number kernels per spikelet, harvest index days heading increased moisture regimes. The genes have any influence on tillers/m2 spikelets spike either regime.
