摘　　要：为了解不同旱地小麦品种的边际优势,选取洛旱22、洛旱6号、安麦1132、洛旱7号、西农219、洛旱19和中麦175等7个旱地小麦品种,测定其产量,结果表明,7个品种的边行产量均高于内行产量;参试品种边行产量由高到低排序为:洛旱22、安麦1132、洛旱6号、西农219、洛旱19、中麦175、洛旱7号。内行产量从高到低依次为洛旱22、洛旱6号、安麦1132、中麦175、洛旱7号、洛旱19、西农219。产量边际优势从高到低依次为西农219、洛旱19、洛旱7号、安麦1132、中麦175、洛旱6号、洛旱22。不同小麦品种间边际优势具有明显的差异,在旱地小麦品种选育和推广中应予以充分考虑。To understand the marginal advantage of different dryland wheat varieties,seven varieties including‘Luohan 22’,‘Luohan 6’,‘Anmai 1132’,‘Luohan 7’,‘Sinong 219’,‘Luohan 19’,and‘Zhongmai 175’were selected.The results indicated that the peripheral rows of these varieties exhibited higher yields compared to the central rows.The ranking of varieties based on yield from highest to lowest was:‘Luohan 22’,‘Anmai 1132’,‘Luohan 6’,‘Sinong 219’,‘Luohan 19’,‘Zhongmai 175’,‘Luohan 7’.The ranking based on overall yield from highest to lowest was:‘Luohan 22’,‘Luohan 6’,‘Anmai 1132’,‘Zhongmai 175’,‘Luohan 7’,‘Luohan 19’,and‘Sinong 219’.The marginal row advantage in yield,ranked from highest to lowest,was observed as:‘Sinong 219’,‘Luohan 19’,‘Luohan 7’,‘Anmai 1132’,‘Zhongmai 175’,‘Luohan 6’,and‘Luohan 22’.There are significant differences in marginal advantages among different wheat varieties,which should be fully considered in the breeding and promotion of dryland wheat varieties.
