摘要：

本研究旨在选育适宜甘肃丝路寒旱区生产性能高、品质优异的青贮玉米杂交种，以满足因青贮饲料短缺而产生的对青贮玉米品种的需求。以G2281为母本、17RT为父本组配作为试验材料，设置5个试验点进行田间性状观测、考种与测产、鉴定与测试等工作。结果显示：在两年多点区域试验中，平均干物质产量达到35162.3 kg/hm2，相较于对照品种增产4.3%，平均增产点超过70%；在一年多点生产试验中，平均干物质产量36048.0 kg/hm2，较对照增产8.7%，增产点达到100%。全株品质分析表明，中性洗涤纤维(NDF)含量39.3%，酸性洗涤纤维(ADF)含量20.2%，粗蛋白(CP)含量7.6%，淀粉(ST)含量30.4%。该品种对腐霉茎基腐病、丝黑穗病具有抗性，抗倒伏倒折能力强，持绿性良好，综合性状表现优良。基于上述研究，成功选育出适应性强的青贮玉米新品种‘金辉658’， 该品种适宜在甘肃丝路寒旱春玉米区推广种植，对青贮玉米产业提质增效具有推动作用。

Abstract:

This study aims to breed high-yielding and high-quality silage maize hybrids suitable for the Silk Road cold and arid region in Gansu, in order to solve the demand for silage maize varieties due to the shortage of silage feed. Experimental materials were derived from a cross between female parent G2281 and male parent 17RT. Five trial sites were established to carry out field trait observation, seed testing, yield measurements, various identification and testing. The results showed that the average dry matter yield from the 2-year multi-point regional trials was 35162.3 kg/hm2, which was 4.3% higher than that of the control group. The rate of average yield increase was more than 70%. The 1-year multi-point production test yielded an average dry matter output of 36048.0 kg/hm2, an increase of 8.7% compared to the control, and yield increase reached 100%. In the whole plant quality analysis, the neutral detergent fiber (NDF) content was 39.3%, acid detergent fiber (ADF) content was 20.2%, crude protein (CP) content was 7.6%, and starch (ST) content was 30.4%. It is resistant to Pythium stem rot and head smut, with strong lodging resistance, good green retention and excellent comprehensive properties. Based on the above research results, a new silage maize cultivar ‘Jinhui 658’ with strong adaptability is selected and bred, which is suitable for planting in cold and dry spring maize area of Silk Road in Gansu Province, and plays a role in promoting the quality and efficiency of silage maize industry.
