摘要: 为了有效评估新品种平麦189的环境适应性、抗逆性及稳产高产性,本研究将其种植于河南省8个不同地区,并对该品种的主要农艺性状进行了详细调查和统计分析。结果表明,平麦189在亩产量、有效穗数、穗粒数、千粒重、最高分蘖数、成穗率、株高、黑胚率等产量及相关性状方面均具有较好的环境适应性和稳定性,同时,该品种的抗旱性和抗病性表现也较为突出。综合分析表明,平麦189在主要农艺性状方面具有较好的广适性和稳定性,其适合在河南省及其周边地区推广种植。

Abstract: To assess the environmental adaptability, stress resistance and high yield of the new wheat variety ‘Pingmai 189’, the yield, effective spike number, grain number per spike, 1000-grain weight, the maximum tiller number, spike forming rate, plant height, black embryo rate of‘Pingmai 189’in different areas of Henan were investigated and analyzed with traditional seed cupping method. Results showed that‘Pingmai189’had better adaptability and stability in many agronomic characters, such as, effective spike number, grain number per spike, 1000-grain weight, the maximum tiller number, spike forming rate, plant height, black embryo rate and other related characters. In addition, the drought resistance index of‘Pingmai189’was 0.921 and its drought resistance level reached the third level in 2015, and that of 2016 was 0.800, which belongs to the fourth level, the comprehensive performance of drought resistance was better. The disease resistance of ‘Pingmai189’to stripe rust and sheath blight was medium in 2015 and 2016. The comprehensive analysis show that‘Pingmai 189’has better wide adaptability and stability in main agronomic characters, and is suitable for planting in Henan and its bordering areas.
