| 摘 要： | 本文以物晚熟多小穗器系１０阿为被测材料，中国春和阿勃两套单体系列为测验系，对抽穗期性状进行了基因定位研究。结果表明，被测系１０阿晚抽穗，受５Ａ，１Ｂ，２Ｂ，６Ｂ和２Ｄ染色体上的隐性基因所控制。其中，２Ｄ染色体上的基因表现为强效，５Ａ，１Ｂ，２Ｂ和６Ｂ染色体上的基因表现为弱效.据前人研究和本试验结果分析认为，被测系１０阿的１Ｂ和２Ｂ染色体上可能具有控制晚熟性的新基因。

| Abstract: | Localization of genes for heading date was carried out in common wheat (Triticum aesti-vum L.) multispikelet line with rather latet heading data, 10-A, by using the monosomic series of the two regular lines, Chinese Spring and Abbondanza. The late heading date of the tested line 10-A was found to be controlled by five recessive genes, located on chromosome 2D (one major effect) and 5A, 1B, 2B, 6B (four minor effect) Accrording to analysis of the results in the previous studies and the present experiment, it was speculated that new genes governing late heading date located probably in chromosomes IB and 2B of the tested line 10-A. |
