烟农24号小麦品种选育及育种技术探讨

Discussion on Selection and Breeding Techniques of New Wheat Variety Yannong 24 with High and Stable Yield

选用丰产稳产、抗旱耐瘠的中肥水小麦品种陕229为母本,用抗病、抗倒的高肥水品种安麦1号为父本杂交,提出并运用单茎库源比理论、高中肥条件下交替选择、杂种后代高密度大群体筛选等育种技术,育成了高产稳产小麦品种烟农24号。该品种分蘖力强,适应性广,抗病抗倒,高产稳产。在山东省小麦高肥区试中,两年平均比对照增产8.45%。2004年通过山东省农作物品种审定委员会审定,2005～2010年连续6年被山东省农业厅、财政厅、科技厅定为山东省优质专用小麦主导品种和小麦良种补贴项目品种。

Yannong 24 was a new wheat variety with strong tillering ability,wide adaptability,disease and lodging resistance,high and stable yield.It was bred using Shan 229 as female parent and Anmai 1 as male parent.In the selection process,the theory of source/sink ratio of single stem,alternate selection under high-middle fertility and high-density large group screening of hybrid progenies were put forward and utilized.The average yield of Yannong 24 was 8.45% higher than that of the control in the regional trials of high fertilizer fields in Shandong Province.It was approved by the Crop Variety Registration Committee of Shandong Province in 2004.Yannong 24 was as the leading variety with good quality for special-purpose,and also as the extended variety of wheat subsidy project during 2005~2010.
