摘要
对2002~2005年度湖北省无子西瓜区域试验中参试品种(系)的产量性状的非平衡资料进行了秩次分析。通过对各品种(系)产量表现平均秩次值H2、环境区分指数YM、秩次均方值S2等统计数的计算,剔除了对品种产量差异区分能力弱的试验点次(试验环境),并进行品种间丰产性、稳产性比较。分析结果与湖北省品种审定和区试结果进行对比,证明用秩次分析法对农作物区域试验中的品种(系)产量性状进行评价是可行的。
The non-balance data of the yield characters of seedless watermelon varieties (lines) in the regional trials during 2002-2005 in Hubei was analyzed using rank analysis method. The testing spots (environments) barely distinguished the yield levels were rejected, and the yield and its stabilities were compared by calculating the ranking value of different varieties (H2),environmental index (YM),and square value(S^2),The results showed that the method was feasible.
