| 摘 要： | 利用化学杂交剂ＳＣ２０５３ 诱导的小麦不育系为母本，与４ 个品质优良的丰产品种配制组合１０８ 个，研究了２９ 个组合各性状的优势表现。结果表明，Ｆ１ 各性状的杂种优势依次为主穗长＞ 千粒重＞ 主穗粒数＞ 主穗结实小穗数＞ 公顷穗数＞ 株高。通过试验，筛选出６ 个强优势组合。

| Abstract: | A wheat sterile induced by a chemical hybridizing agent SC2053 was used as female parent to combine with 4 improved varieties to make up 108 combinations. The superiorities of 29 combinations' characters were studied. The sequence of heterosis of the characters of F 1 was as following: the length of mainhead>the weight of 1 000 grains>grains per mainhead>fruit bearing spikelets per main head>spikes per hectare>plant height. 6 best combinations were selected from the experiment. |
