【摘要】 以49个南瓜组合为试材,采用随机区组设计,对南瓜的植株性状和农艺性状进行对比,并与产量进行相关性分析,以期为选育出适合露地连片规模化种植的鲜食南瓜品种提供参考依据。结果表明:1hm²产量的标准差最大,为909.7kg,说明产量性状在参试组合中的变异幅度大;相关性分析表明,平均坐果数与小区平均产量呈极显著正相关,小区平均产量和单产呈极显著正相关,平均蔓长与平均单产呈极显著正相关;方差分析及产量排序,表明平均单产均呈极显著性,组合292、290、289、288和285的单产排在前5位,产量分别为142 021.8、118 167.3、95 321.2、92 727.3、90 758.8kg·hm^-2。综上,南瓜组合292、288可作为规模化种植的首推品种。更多还原

【Abstract】 The 49 pumpkin combinations were used as test materials,plant traits and fruit traits of all the tested plants and the yield of the plot and the yield per hectare were statistically analyzed by variability analysis,analysis of variance and correlation analysis methods in order to provide a reference for breeding fresh pumpkin varieties suitable for large-scale planting of land contiguous.The results showed that the standard deviation of yield was 909.7kg,which indicated that the variation of yield traits in the test combination was large;the correlation analysis showed that the average number of fruit was significantly positively correlated with the average yield of the plot,and the average yield and yield per unit area were extremely high.Significantly positive correlation,the average vine length was significantly positively correlated with the average yield;variance analysis and yield ranking showed that the average yield was extremely significant,and the combined yields of 292,290,289,288 and 285were ranked in the top five,and the yield was 142 021.8 kg·hm^-2,118 167.3 kg·hm^-2,95 321.2kg·hm^-2,92 727.3kg·hm^-2 and 90 758.8kg·hm^-2.Above all,the combination 292and288 could be used as the main promotion of large-scale planting of pumpkin.更多还原
