摘　　要：以冬性矮败小麦轮选群体为基础,分析轮回选择育成株型紧凑的春小麦新品系的产量变化。结果表明,多点品比试验中,小麦平均产量分别为10 113.0、10 759.5、10 527.0kg/hm2,较宁春4号(对照)分别极显著增产11.4%、18.5%、15.9%。播种量900万粒/hm2时,陇春1032产量最高,达到11 091.0kg/hm2;播种量825万粒/hm2时,粗秆大穗大叶品种陇春30号产量最高,为10 552.5kg/hm2。以提高成穗数为目标,选育株型紧凑且适宜密植的春小麦品种,可进一步提高该地区小麦单产。The yields of new spring wheat lines with compact plant-type were analyzed, which were bred by recurrent selection technique on the basis of winter dwarfing-sterile wheat. The results showed that the average yields of Longchun 1013, Longchun 1032 and Longchun 1056 were 10 113. 0, 10 759. 5 and 10 527. 0 kg/hm^2, which were improved extremely significantly by 11. 4 %, 18. 5 % and 15. 9 % compared to Ningchun 4 as the control in multi-point yield trials. The yield of Longchun 1032 was the highest （11 091 kg/hm^2） in the sowing density of 900 × 10^4 /hm^2 while the yield of Longchun 30 was the top with 10 552.5 kg/hm^2 in the sowing density of 825 ×10^4 /hm^2 Therefore, the wheat yield could be further improved by increasing the number of spikes, breeding new spring wheat varieties with compact plant-type and suitable close planting in Hexi irrigation area.
