Abstract
In order to understand the characteristic of nitrogen uptake and utilization and selecting high nitrogen use efficiency genotype in eggplant.Field experiment and testing analysis were conducted to study the genotypic variation in nitrogen use efficiency in ten genotypes of eggplant by quantify analyzing fruit yield,nitrogen utilization efficiency,nitrogen response and total nitrogen.The results showed that there were significant genotypic variations in fruit yield,nitrogen utilization efficiency,nitrogen responsiveness and total nitrogen among different eggplant genotypes whatever nitrogen application rate.The tested eggplant genotypes could be classified into five different types based on their nitrogen use efficiency.06-991 belonged to HH-LH type(high N use efficiency at high nitrogen level,high N use efficiency at low nitrogen level);06-917 belonged to HH-LM type(high N use efficiency at high nitrogen level,mid N use efficiency at low nitrogen level);06-961 and 06-867 belonged to HH-LL type(high N use efficiency at high nitrogen level,low N use efficiency at low nitrogen level);06-972,06-947,06-854,06-830 and 06-909 belonged to HM-LL type(mid N use efficiency at high nitrogen level,low N use efficiency at low nitrogen level);06-910 belonged to HL-LL type(low N use efficiency at high nitrogen level,low N use efficiency at low nitrogen level).Through path analysis,it was found that the effect of total nitrogen on nitrogen use efficiency was more important than nitrogen utilization efficiency.
