摘　　要：为了使保大麦25号在生产中发挥更大的增产潜能,以2016—2017年保山市大麦多点试验以及2017—2019年云南省饲料大麦区域试验数据为分析资料,对保大麦25号的丰产性、稳定性、适应性及其产量构成因素进行多重分析,结果表明保大麦25号的丰产性、稳定性、适应性均优于对照品种。主要农艺性状中与产量相关程度由高到低依次为穗实粒数(0.3973)、有效穗(0.3560)、茎蘖总数(0.2052)、株高(0.1550)、千粒重(0.0707)、基本苗(0.0003);对产量的直接影响由高到低依次是穗实粒数(0.4987)、千粒重(0.4249)、有效穗(0.3605)、株高(0.2683)、茎蘖总数(0.2335)、基本苗(0.0652);与产量的关联度由高到低依次是穗实粒数(0.4611)、株高(0.4583)、有效穗(0.4377)、千粒重(0.4180)、茎蘖总数(0.3866)、基本苗(0.3642)。In order to make Baodamai 25 play a greater yield potential in production,the yield,stability,adaptability and yield components of Baodamai 25 were analyzed based on the data of multi-point test of barley in Baoshan City from 2016 to 2017 and reginal test of forage barley in Yunnan Province from 2017 to 2019.Results showed that the yield,stability and adaptability of Baodamai 25 were better than those of the control varieties.The correlation degrees of main agronomic traits with yield from high to low was as follows:filled grain number per panicle(0.3973),effective panicle(0.3560),total number of tillers(0.2052),plant height(0.1550),1000-grain weight(0.0707),basic seedlings(0.0003).The direct effects on yield from high to low were as follows:filled grains per panicle(0.4987),1000-grain weight(0.4249),effective panicles(0.3605),plant height(0.2683),total tillers(0.2335),basic seedlings(0.0652).The correlation degree with yield from high to low was as follows:grain number per panicle(0.4611),plant height(0.4583),effective panicles(0.4377),1000-grain weight(0.4180),total tillers(0.3866),basic seedlings(0.3642).
