摘　　要：为了给关中西部台塬地区及相近气候环境条件地区小麦育种和栽培管理提供参考,通过分析当地种植的9个小麦品种的株高、地上部生物量、667 m^(2)穗数、千粒重等农艺性状与产量的相关性,发现参试品种667 m^(2)穗数与产量呈显著正相关性。综合来看,建议适当提高667 m^(2)穗数,兼顾千粒重,控制穗粒数。分类型看,中短期内,建议在气候环境相似地区推广种植高产类型和中高产类型品种。增产建议:针对高产、低产类型,适当提高667 m^(2)穗数,控制千粒重,稳定穗粒数;针对中高产类型,适当提高667 m^(2)穗数,控制穗粒数,稳定千粒重;针对中低产类型,适当提高穗粒数,控制千粒重,稳定667 m^(2)穗数。To provide a reference for wheat breeding,cultivation and management in the Plateau region of western Guanzhong and areas with similar climatic and environmental conditions,the correlation between agronomic traits such as plant height,aboveground biomass,spikes per 667m^(2),and 1000-grain weight,and yield across nine locally grown wheat varieties was analyzed.The number of spikes per 667m^(2) exhibited significantly positive correlation with yield.In summary,it is recommended to appropriately increase the number of ears per 667m^(2),while considering 1000-grain weight and controlling the number of grains per ear.In terms of variety classification,it is suggested promoting the cultivation of high yield type and medium high yield type varieties in areas with similar climates and environments in the short to medium term.Specific measures for yield improvement include:for high and low yield types,appropriately increasing the number of ears per 667m^(2),controlling 1000-grain weight and stabilizing the number of grains per ear;For medium to high yield type,appropriately increasing the number of spikes per 667 m^(2),controlling the number of grains per spike,and stabilizing the 1000-grain weight,For middle to low yield types:appropriately increasing the number of grains per ear,controlling 1000-grain weight,and stabilizing the number of spikes per 667m^(2).
