摘　　要：在黄淮冬麦区旱作条件下对20个旱地小麦品种进行了筛选试验。试验结果表明:产量超过6000 kg/hm^2的品种有7个,即西农928、长6359、洛旱6号、衡136、西农219、洛旱7号和长旱58;其高产经济性状指标为成穗数(420.00~485.10)万穗/hm^2,千粒重45.96~50.01 g,穗粒数31.00~34.40粒,收获指数40.95%~43.13%,株高86~96 cm,水分利用效率14.12~16.38 kg/(mm·hm^2);越冬期、拔节期、孕穗期和抽穗期的群体大小应分别为成穗数的1.88、3.35、2.26和1.51倍;越冬期、拔节期、孕穗期、开花期、收获期的干物质积累量应分别占总干物质量的3.20%、16.85%、23.08%、26.81%、30.07%。The screening tests for 20 winter wheat varieties were carried out under the condition of dry farming in Huanghuai area. Seven wheat varieties with the yield of more than 6000 kg/hm2 were screened out, and they were Xinong 928, Chang 6359, Luohan 6, Heng 136, Xinong 219, Luohan 7 and Changhan 58. The high-yielding economic indexes of these wheat varieties were determined as follows： the number of formed spikes per hectare was 4200000~4851000; the kilo-grain weight was 45.96- 50.01 g; the number of grains per spike was 31.00 ~ 34.40; the harvest index was 40.95 % ~ 43.13 % ; the plant height was 86 ~ 96 cm ; the water use efficiency was 14.12 ~ 16.38 kg/（ mm · hm2 ）. The population size of wheat plants at overwintering stage, joint- ing stage, booting stage and heading stage should be the 1.88, 3.35, 2.26 and 1.51 times the number of formed spikes, respec- tively. The accumulation of dry matter in wheat plants at overwintering stage, jointing stage, booting stage, flowering stage and harvest stage should account for 3.20%, 16.85%, 23.08%, 26.81% and 30.07% of total dry matter accumulation, respectively.
