The objective of this study was carried out to analysis of genotypic diversity based on agronomical traits in 213 accessions of rocket.
The results showed thatrocket genotypes had very large distribution patterns in plant height, plant width, plant erect index, and length of bolting stem.
The average values of plant height, plant width, plant erect index, and length of bolting stem in the cultivated genotypes or wild genotypes from native area are higher than those in cultivated genotypes or wild genotypes from non-native area, respectively, except plant width of wild genotypes.
The wild genotypes from native area are narrower than that from non-native area.
The high percentage of rocket genotypes (about 41% in 213 genotypes) started bolting with 4-5 leaves and some plants even had flower buds.
However, late bolting genotypes (21% genotypes) in this experiment could be used for selecting later bolting cultivars.
