To overcome the problematic detection of Bean yellow mosaic virus (BYMV) concentration in gladiolus corms or cormlets, we tested suitability of different diagnostic methods such as ELISA, one step RT-PCR and IC-RT-PCR. Among these methods, DAS-ELISA and one step RT-PCR method was able to detect virus in leaves and it failed to detect in corms or cormlets whereas IC-RT-PCR method was very sensitive and able to detect virus in both leaves and corms or cormlets of gladiolus plants this is due to during an RNA isolation step and viral particles are enriched by antibody or plastic affinity capture whilst PCR inhibitors are eliminated from the sample during the immunocpature stage of the test. Therefore, IC-RT-PCR was the most reliable method of diagnosing BYMV in gladiolus corms or cormlets.

Soaking corms in distilled water improved the propagation and development of cormlets, suggesting the potential leaching-out of inhibitory chemical compounds. To investigate the presence of inhibitory compounds, nuclear magnetic resonance (NMR) spectral data of the leachate from dormant corms were obtained using a 600 MHz H-NMR spectrometer. The H-NMR analysis led to the identification of choline, succinate, propylene glycol, and lactose, as inhibitory compounds.

Saffron ( L) is a triploid (2n = 3x = 24), sterile geophyte which can only be propagated by means of underground vegetative corms. Since corm multiplication does not induce genome variations, therefore, the entire saffron population is expected to have a similar genetic makeup. Keeping in view the economic importance of the plant and the factors responsible for its low yield, the present investigation has been undertaken to establish an in vitro ethyl methanesulfonate (EMS) mutagenesis protocol followed by characterization of the induced variability in the advanced generations.
