Ebook "Tomato yellow leaf curl virus disease: Management, molecular biology, breeding for resistance" will awaken the interest of breeders, phytopathologists, environmentalists, extension services, plant virologists, entomologists and molecular biologists. It deals both with the epidemiological aspects of the disease and with integrated pest management in the field. It discusses the efforts aimed at breeding tomato plants resistant to the virus (using classical breeding, marker-assisted breeding and genetic engineering).

Tomato leaf curl disease caused by tomato leaf curl virus (ToLCV) is a major limiting factor in tomato cultivation in Jammu region of Jammu and Kashmir. Screening of different germplasm collected from different sources against the disease showed that out of fifteen germplasm, Mahaveer and Avinash-2 were found resistant, Samrudhi F1 and Namdhari 82535 were found moderately resistant while eleven germplasm viz. Heem Sohna, Sonali, Rupali, NS 816, NS 812, Pusa Ruby, Indus 1030, Arti, DVRT-2, Hybrid no. 15 and local showed susceptible reaction.

The front line demonstrations (FLD’s) on Arka Rakshak F1 Hybrid of tomato were conducted by Krishi Vigan Kendra of Ramanagara District, Karnataka. Akra Rakshak, a triple disease resistant (bacterial wilt, early blight and leaf curl virus) hybrid was released by Indian Institute of Horticultural Research (IIHR), Bengaluru. Improved crop management practices were demonstrated in farmers field for three consecutive years from 2014-15 to 2016-17. As an outcome of FLD, it was noticed that the average per cent Bacterial wilt affected plants was low in demo plots (1.

The simple sequence repeat (SSR) or microsatellite marker is currently the most preferred molecular marker because of its reproducibility and codominant nature. The aim of this study was to validate SSR markers for bacterial wilt (BW) and tomato leaf curl virus disease (ToLCV) in tomato. DNA isolated from the parents Mukthi and IIHR-2195 was used to validate five SSR primers already reported for BW and ToLCV. One primer SSR20 which showed good polymorphism and reproducibility among parents were selected for further validation in F3 and F4 population.

Thirteen single cross hybrids were evaluated at Mudhude village, Arsikere taluk, Hassan district, Karnataka during summer 2017 under IDM and Non-IDM conditions with the objective of testing the performance of commercial hybrids and resistance to bacterial wilt and ToLCV diseases. The top three high yielders were Abhinav, Badshah and 1057.

Tomato leaf curl virus disease (ToLCVD) is one of the major causes for highest economical loss of tomato in India. In this study, Natural incidence of ToLCV disease on tomato was observed at Gujarat, India in the March, 2019. The infected plants revealed systemic viral symptoms in the form of sever leaf curling, leaf crumple with marginal yellowing, stem warped and stunted. Molecular methods were followed to further characterized coat protein (CP) gene of tomato leaf curl virus using specified primers.

Tomato leaf curl disease is the most devastating disease, caused by tomato leaf curl virus (ToLCV) a Gemini virus transmitted by the vector Bemesia tabaci Gen. In this study 17 F2:3 families of tomato derived from the cross IIHR 2201 x C-13-1-2-1 along with the parents IIHR 2201, C-13-1-2-1 and check Arka Vikas (Succeptible), Arka Rakshak(Resistant) were screened against resistant/ Succeptible reaction for tomato leaf curl disease under field condition, during 2017-18 from end of October to beginning of February in the Department of Vegetable Science, College of Horticulture, Bengaluru.
