Abstract
A study was conducted on “Characterization and seed vigour assessment” to identify sixty
genotypes under study. Plant morphological characters like plant growth habit, seeds per
umbels, umbels per umbellate ,arrangement of seeds in main umbel and yield per plant (g)
were found to be the most important diagnostic characters for cultivar identification in fennel.
Some seed morphological characters like test weight, seed colour, seed shape and seed
splitting habbit were also found helpful to differentiate the fennel cultivars. The differential
response of fennel genotypes to different chemical tests such as phenol test, modified phenol
test-A, modified phenol test-B, and potassium hydroxide test was found to be very effective
for genotype identification. The schematic diagram on the basis of some important
morphological traits has higher resolution in terms of differentiating among genotypes. The
schematic diagrams based on plant growth characters, seed parameters and chemical test are
also very useful for identification of genotypes. Field keys were prepared for each and every
genotype on the basis of some highly heritable characters with wide variability. This field
keys has a pivotal role to identify genotypes in the field without any use of coastly chemicals
and are fairly comparable with their results.
