| In order to know the characters of wheat germplasm from Hubei, and offer groundwork for finding out the best germplasm in breeding. In this study, the geographical distribution, agronomic traits, quality and disease resistance of 874 wheat germplasm from crop germplasm bank of Hubei were evaluated. The results indicated that the wheat germplasm were main concentrated in the plains and hilly areas, which distributed evenly except in that longitude from 112 ° 74 'to 114 ° 15', latitude from 31 ° 18 'to 32 ° 09', and south of the north latitude 29 ° 37 '. The largest amount accessions were distributed in Jianghan Plain, and the most enriched species were in mountain area of northwest Hubei. Most local resources had long awns, white shell, red grain, weak winter, and mid-maturing properties. The characters with great variation and diversity index were observed in four yield traits (plant height, thousand kernels weight, spike length and grain numbers per spike) and four quality properties (hardness, sedimentation volume, gross protein content and lysine content). The resistance was the strongest to root rot, barley yellow dwarf virus and stripe rust, but resistance was the least to fusarium head blight, leaf rust, stem rust and powdery mildew. The diversity index was decreased as the following characters: thousand kernels weight, gross protein content, lysine content, plant height, grain numbers per spike, sedimentation volume, spike length, hardness, stripe rust, barley yellow dwarf virus, leaf root rot, maturity, fusarium head blight, spike root rot, winter-spring characteristic, awn, chaff color, powdery mildew,grain color, leaf rust, stem rust. The results were important reference to wheat genetics and breeding, and germplasm innovation and utilization. |
