| 中文摘要: |
| 小麦新品系鄂麦28具有中抗赤霉病、抗穗发芽、高产稳产等突出特点。为利用其剩余变异，从其群体中系统选择了30个新品系，2018-2019年度通过武汉和襄阳两地的田间鉴定试验，比较了它们的产量及其构成、株高、生育期等性状，并利用小麦21对核心SSR引物对鄂麦28典型单株进行遗传相似性检测。结果表明，18S314、18S325、18S239、18S331等4个高产品系经核心引物检测，所有位点与鄂麦28典型单株基因型一致，可作为鄂麦28优系进行利用。18S278和18S279两个品系具有特异性，产量较高，可以作为新品系进行利用。18S268、18S293、18S317、18S318等4个品系特异性不明显，但产量较高，且田间农艺性状表现出一定的差异，也可作为新品系进一步利用。 |
| 英文摘要: |
| A newly selected elite wheat line Emai 28 performs moderate resistance to Fusarium head blight, resistance to pre-harvest sprouting, high and stable yield. To make good use of its residual variances,30 lines re-selected from Emai 28 were tested in field trails in Wuhan and Xiangyang, Hubei province in 2018-2019 crop season. Agronomic traits, such as grain yield components,plant height and growth period were compared.The genetics milarity between the typical plant of Emai 28 and its re-selections were tested using 21 pairs of core SSR primers. Four high-yield selections 18S314, 18S325, 18S239 and 18S331 had the same genetic variation with Emai 28.They can be used aselite lines to replace Emai 28.Two selections 18S278 and 18S279 were distinctively different from Emai 28 and had high grain yield.These two lines can be used as new lines in breeding.Four high-yield selections 18S268,18S293, 18S317 and 18S318 with out distinctness showed different traits in field could also be used as new germplasms in breeding. |
