全国小麦杂种优势利用研究学术讨论会于2月25日至8月2日在京召开,28个单位、57名代表参加了会议。会议共收到学术论文17篇,研究年度报告17篇。这次会议交流的论文,在深度和广度上都反映出我国小麦杂种优势利用研究工作的新高度和新水平。在广度上,从农艺性状到品质性状,从高产半矮秆杂种小麦的培育到杂种小麦最适宜密度的研究,从化学杀雄到新三系选育;在深度上,从地下部根系测定到地上部花药显微观察,从育性恢复的遗
National Wheat Heterosis Research Symposium was held in Beijing from February 25 to August 2, 28 units and 57 representatives attended the meeting. The conference received a total of 17 academic papers, 17 annual reports. The papers exchanged at this meeting reflect both the new height and the new level of utilization of wheat heterosis in China both in depth and breadth. In terms of breadth, from agronomic traits to quality traits, from the cultivation of high-yield semi-dwarf hybrid wheat to the optimum density of hybrid wheat, from chemical killing to new three-line selection; in depth, from the root of the underground to Aboveground anthers microscopic observation, from the fertility recovery legacy
