| Abstract: | To construct our own mutant library and provide materials for germplasm innovation and illustration of mechanisms involving in agronomic traits in barley and crops, mutant population of barley Edamai 934, which was an elegent cultivar bred by Hubei Academy of Agricultural Sciences, was constructed using60Co-γ combined with EMS. Totally 982 mutants were identified, which showed significant and hereditable changes as compared with the wild type Edamai 934 on one of the following traits, leaf, stem, spike, seed, tiller, plant architecture, heading date, seed setting rate, and so on. Further cytological analysis of leaf width mutants showed that size and morphology of cells from flag leaf of different mutants varied a lot, suggesting that different mechanisms may involve in. This study lays foundation for barley functional genomics. |
