我省近年育成一些大豆新品种,通过三年区域试验,有些品种表现比较好。为鉴定它们在不同农业生态环境和不同生产条件下的表现及利用价值,并做出较合理的评价,有利于充分发挥其潜力。我们在各点区试的基本数据的基础上,进行了一些适应性和稳定性分析。 一、材料和方法 供试材料为全省春大豆新品种区试的6个品种,试验点7个。田间采用随机区组排列,重复3次,小区面积0.015亩,田间记载和室内考种按统一标准进行。 稳定性参数的估算采用Eberhart-Russell法。该法提出两个参数测 Some new soybean varieties have been bred in recent years in our province. After three years of regional trials, some varieties have performed well. In order to identify their performance and utilization value under different agro-ecological environment and different production conditions and to make a more reasonable evaluation, it is beneficial to fully realize their potential. Based on the basic data of each area test, we carried out some adaptability and stability analysis. First, materials and methods The test materials for the province’s spring soybean new varieties of regional testing of six varieties, seven pilot points. Field randomized block arrangement, repeated 3 times, the plot area of ​​0.015 acres, field records and indoor test according to uniform standards. The stability parameters were estimated using the Eberhart-Russell method. The law proposed two parameters measured
