Abstract

Sesame (Sesamum indicum L.) belongs to family pedaliaceae, which have basic chromosome number 2n =26 and originated in India. It is oldest oilseed crop. The sesame phyllody was observed to be widely distributed the entire ten village of Jaipur district. , a roving survey of sesame fields at 50 per cent capsule forming stage in Jaipur district near in 10 locations were under taken during Kharif-2019. The maximum disease incidence was recorded at Bhutera (26.05%) followed by Pachkodiya (25.23%) and the severity of sesame phyllody in surveyed areas was from 17.90 to 26.05%. Among the environmental factors effecting sesame phyllody were minimum temperature, relative humidity and rainfall that increase both leaf hopper population and per cent disease incidence except maximum temperature which show non-significant negative correlation with disease incidence and leaf hopper population.

Keywords

Phyllody, temperature, disease incidence, leaf hopper.

Conclusion

The incidence of sesame phyllody varied from village to village in the ten village of Jaipur district during survey and it was maximum in Bhutera village (26.05%) and minimum in village Dhani Boraj (17.90%). Typical symptoms of sesame phyllody under investigation were phyllody, virescence, witches’ broom, stunting, yellowing and sterility. Among the environmental factors effecting sesame phyllody were minimum temperature, relative humidity and rainfall that increase both leaf hopper population and per-cent disease incidence except maximum temperature which show non-significant negative correlation with disease incidence and leaf hopper population.

Sesame (Sesamum indicum L.) belongs to family pedaliaceae, which have basic chromosome number 2n =26 and originated in India. It is also Known as til (Hindi), tal (Gujarati), till (Panjabi), nuvvulu (Telugu), ellu (Tamil) and ragi (oriya) in different til growing parts of India. Sesame is an important annual oilseed crop which requires warm and hot climate and commonly grown under stressed condition from tropical to temperate region. Sesame is an annual, tall growing (1.0 to 1.5 meter) herbaceous plant which mature in about 90 to 110 days. As an ancient and important oily seed crop, sesame is cultivated mainly for its valuable edible oil used for human cooking oil and besides its positive human health benefits (Jayaraj et al., 2020). Due to its amazing cosmetic and skin-care properties it’s oil widely used in shampoos, massage toilatery products, soaps, detergents, pharmaceuticals and perfumes etc. and due to these properties, it is called “Queen of oils” (Anonymous, 2006).
