四川省农科院作物所选育的川麦 2 8,是近 5年来以 80 - 8为对照增产点次率最高、增产幅度最大的新品种。本文根据两年四川省小麦区试资料用 Eberhart- Russell法进行稳产性分析。川麦 2 8的稳定性参数接近于稳产品种的理论值 ,G× E互作效应主要表现为线性关系 ,具有较好的平均稳定性。稳定性的分析结果与区试、生产示范的实际情况相吻合 ,充分表明川麦 2 8产量高、稳产性好、适应范围广的特点 ,符合主推品种要求。
Sichuan Academy of Agricultural Sciences crop Chuanmai 28, 80 to 8 in the past five years as the control point yield highest yield the largest new varieties. In this paper, two years of wheat test data in Sichuan Province by Eberhart-Russell method for stability analysis. The stability parameters of Chuanmai 28 are close to the theoretical values of stable varieties. The G × E interaction effect is mainly linear and has good average stability. The results of the stability analysis are consistent with the actual situation of the zone test and the production demonstration, which fully shows that Chuanmai 28 has the characteristics of high yield, good stability and yield and wide adaptability, which meets the requirements of the main push variety.
