摘要
为了评价小麦新品种(系)在不同生态条件下的丰产稳产性,应用高稳系数(HSC)法与常规分析方法相结合对2001～2002年甘肃省水地春小麦区域试验东、西片试区19个参试品种(系)的丰产性与稳产性进行了分析。结果表明,东片参试品系98SN146、93元-7、CM4860以及西片参试品系91D58-4、石1269、酒86141的标准差、变异系数和HSC值较小,HSC值分别为26.78%、27.69%、27.73%、18.07%、18.14%和22.42%,说明这些品系的丰产稳产性较好。研究表明,用高稳系数法评价小麦新品种(系)的丰产稳产性是可行的,将两种方法结合应用能更准确地反映小麦新品种(系)的丰产稳产性。
By using regional test data conducted by Gansu province during the years of 2001~2002, the high and stable yielding characters of 19 spring wheat cultivars were analyzed with high stable coefficient (HSC) method. Several parameters of conventional statistical methods and HSC have been compared and analysis. The results showed that 98SN146, 93Yuan-7, CM4860, 91D58-4, Shi 1269 and Jiu 86141 had lower S、CV and HSC, their HSC were 26.78%, 27.69%, 27.73%, 18.07%, 18.14% and 22.42%, (respectively). The high stable coefficient is an good integrated index on the evaluation of high stable yielding characters of spring wheat varieties and combine HSC with conventional methods have a better effects.
