【摘要】 <正> 长江下游区第二轮全国甘蓝型优质油菜新品种(系)区域试验,从1986年开始(收获年,下同),连续进行了三年至1988年已告结束。各试点对参试品种(系)的丰产性、抗逆性等均已做了较详尽的总结。本文借助1986至1988三个年度、24个点次的产量试验结果,在各试点试验总结的基础上,试图运用数理统计分析方法对参试品种(系)的丰产性、稳产性进行综合分析,以期进一步提高试验的准确性,为新品种的合理应用和推广提供理论依据。一、供试品种(系)和分析方法供试品种(系)计8个,分别是苏124、617、609、75—17—2(以上均为低芥酸品系)、3151、24016(双低品系)、84-更多还原

【Abstract】 The yield and stability of the improved single or double-low rapes eed entered district experiment was studied, The results were shown as follows.1. The yield and stability for 84—1 and 609 is better than the others. the line 84—1. demonstrats its high yield ability under common or favourable cultivating condition.2. Yield stability indicated by regressive and determinate coefficient is the important criterion of cultivar evaluation.3. Regressive equation exhibits the relation between lines and environment. while some error illustrated by determinate coefjicien(?) remines between the values observed and estimated.更多还原
