筛选适宜甘肃中部灌区推广种植的高产优质春小麦品种,为当地春小麦提质增产提供参考。对引进的4个春小麦新品种进行品种比较试验,测定参试品种的产量、经济性状、生物学性状和品质性状。结果表明,陇春44号、武春11号、酒春14号的折合产量分别为6 787.50、6 240.28、6 087.50 kg/hm2,较对照品种宁春4号分别增产32.30%、21.63%、18.65 %;成穗率分别较对照品种宁春4号高6.1、3.5、1.4个百分点,穗粒数分别高27.6%、3.3%、5.0%,蛋白质含量高11.6%、11.6%、2.3%。陇春44号和武春11号生育期适中、抗逆性强、成穗率、穗粒数高,加工品质和营养品质好,适宜进行大面积示范推广种植,而酒春14号因其农艺性状、抗逆性较好,可作为备选品种进行适度规模示范种植。

[Abstract]
In order to screen out high-yielding and high-quality spring wheat varieties suitable for popularization in the irrigation areas of central Gansu and to provide a reference for improving local spring wheat production, 4 newly introduced spring wheat varieties were tested and compared in terms of yield, economic traits, biological characteristics, and quality traits. Results showed that average yields of Longchun 44, Wuchun 11 and Jiuchun 14 reached 6 787.50, 6 240.28 and 6 087.50 kg/ha, respectively, with yield increases of 32.30%, 21.63% and 18.65% over the control variety Ningchun 4. Compared with the control, the spike rates of Longchun 44, Wuchun 11 and Juchun 14 were 6.1, 3.5 and 1.4 percentage points higher, respectively, the number of grains per spike increased by 27.6%, 3.3% and 5.0%, and the protein content increased by 11.6%, 11.6% and 2.3%. Longchun 44 and Wuchun 11 had moderate growth periods, strong resistance to diseases, pests and adverse conditions, high panicle formation rates and grain numbers per spike, as well as good processing and nutritional qualities, making them suitable for large-scale demonstration and promotion planting. Jiuchun 14, due to its superior agronomic traitsand stress resistance, could be used as an alternative variety for moderate-scale demonstration planting.
