Two highly resistant genotypes of wheat viz. HD 29 and DWL 5023 and one highly susceptible genotype WL 711 against Karnal bunt (KB) disease were studied for their difference in morphological features, growth parameters and isozyme patterns. It revealed that both the resistant genotypes were bearing higher number of spikelets with short internodes in the spike as compared to the susceptible genotype. In contrast WL 711 had significantly higher number of stomata in sheaths, flag leaf base, booted glumes and rachis. The hair count was significantly high on the glumes and rachis of HD 29 and DWL 5023 than on WL 711. HD 29 possessed significantly narrow glume opening distance between lemma and palea followed by DWL 5023 and WL 711. Moreover, the period between ear emergence and anthesis was short in HD 29 followed by DWL 5023 and WL 711. Out of the twelve isozyme systems performed using seeds and seedlings of the genotypes, majority of them gave rise to comparatively higher number of bands in HD 29 and DWL 5023 than in WL 711. However, specific band(s) for each genotype were very less. Cluster information was the same for morphological data and isozymic banding patterns in Unweighted Pair Group Method with Arithmetic Averages (UPGMA) analysis where both the resistant genotypes together formed a cluster leaving susceptible genotype alone in a separate cluster. Comparison between morphological features and isozyme patterns of the wheat genotypes in relation to KB disease is discussed.
