压砂地西瓜新品种的丰产性和稳产性分析

Analysis on Productivity and Stability of Watermelon Varieties in Gravel-mulched Field

以2009年国家西瓜品种区域试验的8个西瓜品种和4个试点的产量数据为依据,通过使用DPS软件对产量进行一年多点的方差分析和多重比较,评价了西瓜品种在压砂地上的丰产性和稳产性。方差分析结果表明,品种09-N7、09-N1和09-N15之间存在显著差异,品种09-N7、09-N1、09-N15和其他品种存在极显著差异。品种的丰产性和稳定性结果表明,8个品种中,09-N1和09-N7丰产性和稳产性均优于对照09-N15,09-N1和09-N7为丰产稳产品种;品种09-N9变异度小于对照,稳产性优于对照,但其丰产性较差,为低产稳产品种。

This research carried out variance analysis and multiple comparisons on yield of varieties in multipoint a year by using DPS, evaluated productivity and stability of watermelon varieties in gravel-mulched field according to yield results of eight watermelon varieties and four testing sites in regional trial in China. The results of variance analysis showed that three varieties （09-N7, 09-N1 and CK） were significantly different and three varieties （09-N7, 09-N1 and CK） reached extremely significant differences with other varieties. The results of productivity and stability of watermelon varieties showed that productivity and stability of 09-N1 and 09-N7 were superior to the control, 09-N1 and 09-N7 were high and stable yield varieties, productivity of 09-N9 was inferior to the control and stability of 09-N9 was superior to the control, 09-N9 was low and stable yield variety.
