摘　　要：本研究针对宁夏南部山区落后的生产条件及特殊的气候生态类型,对选育的16个小麦品种进行适应性、丰产性、抗逆性鉴定,其目的是筛选出特征特性良好,丰产性状突出,适合宁夏南部雨养条件下不同生态区域的旱地冬小麦品种(系)。结果表明,陇中1号、NB9667-13、陇鉴107、陇鉴103、Z0229-4-3、9924、Z0231-3-1、2007-1-113和Z0228-2-2九个品种(系)在两点试验中都较对照增产,增幅1.11%~31.95%;Z0349-4、Z0230-2、Z0229-4-113、X0309-14-3和Z0309-18-2五个品种(系)在两点都较对照减产,减幅100%~0.49%,沧2007-1-1-1-1在一个点表现减产。通过聚类分析,将16个品种(系)分为5大类。4个品种(系)在E1点适应性好(较好),5个品种(系)在两点适应性好(较好),其他在E1、E2点都表现较差或不好。This study focuses on the disadvantaged production conditions and unique climate ecotypes in the south⁃ern mountainous region of Ningxia.It evaluates the adaptability,productivity,and stress resistance of 16 selected wheat varieties.The objective is to identify dryland winter wheat varieties(lines)with favorable characteristics and prominent yield traits that suit different ecological regions under rain-fed conditions in southern Ningxia.The re⁃sults indicate that nine varieties(lines),namely Longzhong 1,NB9667-13,Longjian 107,Longjian 103,Z0229-4-3,9924,Z0231-3-1,2007-1-113,and Z0228-2-2,show increased yields compared to the control group in twopoint experiments,with an increase ranging from 1.11%to 31.95%.On the other hand,five varieties(lines),namely Z0349-4,Z0230-2,Z0229-4-113,X0309-14-3,and Z0309-18-2,exhibit decreased yields at two points,with a reduction ranging from 100%to 0.49%.However,Cang2007-1-1-1-1 shows reduced yields at one point but in⁃creased yields at another.Through cluster analysis,16 varieties(lines)are divided into 5 major categories.Four vari⁃eties(lines)have good adaptability at point E1(better),five varieties(lines)have good adaptability at two points(bet⁃ter),and the others all show poor or bad performance at points E1 and E2.
