Abstract

Seed is an important input for crop production. Seed carries various types of fungi which may be pathogenic and non-pathogenic known as seed mycoflora or seed-borne fungi. Seed-borne diseases had an adverse impact on the quality of chilli and tomato production. So to determine the presence and significance of fungi on seeds, the present investigation was carried out to identify the various mycoflora associated with chilli and tomato seeds and to determine the seed health by testing via blotter paper, PDA and water agar methods. Twelve number of seed mycoflora were isolated from chilli and tomato seeds collected from the West Garo Hills district of Meghalaya and the Dimapur district of Nagaland. The identified fungi were Aspergillus niger, Aspergillus fumigatus, Aspergillus sp.1, Aspergillus sp.2, Aspergillus sp.3, Rhizopus sp., Penicillium sp., Alternaria solani, Fusarium sp.1, Fusarium sp.2, Fusarium sp.3 and Unidentified sp.1. Among these fungal species, Fusarium sp.3 (63.55%) was the most predominant fungus followed by Aspergillus niger (49.17%) and Aspergillus fumigatus (41.88%). Among the different seed health testing methods, a similar number of fungal species were recorded in blotter paper and PDA methods and the least in the water agar method.

Conclusion

The results from the present studies, we concluded that the chilli and tomato cultivars collected from West Garo Hills of Meghalaya and Dimapur districts of Nagaland states of India respectively had wide diverse seed borne mycoflora which may be either pathogenic or non-pathogenic in nature. Since tomato and chilli are the very important vegetables crops in the North Eastern regions as well as in the country as a whole, it may be inferred from the present investigations that adoption of better seed health testing is very important steps for successful cultivation of chilli and tomato.
