摘　　要：运用基于熵权的多目标决策评价模型,对19份红小豆品种进行鉴定与评价。结果表明,参试品种间的主茎分枝、单株粒重、单株结荚数和株高的差异最大,变异系数均在20%以上,以主茎分枝的变异系数最大,达到29.41%;品种间产量差异达到极显著水平,‘品红2000-47’产量最大,‘白红5’产量最低;结合12个性状进行综合评价,唐山本地的2个品种综合性状最好,但这两个品种生育期较长、株型较高,不适宜现代育种的目标;综合性状较好的‘保红947’、‘保876-16’、‘品红2000-47’和‘品红2000-107’在唐山地区可优先示范推广。19 azuki bean varieties were identified and evaluated by Multiple objective decision making（MODM） on entropy coefficient. The results showed that greater differences were revealed in branches in main stem, seed weight per plant, pods per plant and plant height between the varieties. The average variable coefficient was above 20 % and the variable coefficient of branches in main stem was maximum（29.41%）. Meanwhile, differences of yield reached the most significant level and among these, the yield of ＇Pinhong 2000-47＇ was the highest and ＇Baihong 5＇ was the lowest. Comprehensive evaluation of twelve characters indicated that two Tangshan local varieties had the best comprehensive characteristics, but characteristics of longer growth period and higher plant type made them not to accord with the modern breeding goal. ＇Baohong 947＇, ＇Bao 876-16＇,＇Pinhong 2000-47＇ and ＇Pinhong 2000-107＇ with better comprehensive characteristics could be demonstrated and popularized preferentially.
