Abstract

Tomato is the major vegetable crop grown in Chittoor District of Andhra Pradesh. Biotic stresses like late blight, early blight, Tuta absoluta causing severe yield losses to the farmers. Late blight is the major problem in tomato from September to January months causing severe yield losses to the farmers. Local private hybrids are susceptible to the disease and farmers used to spray fungicides for 5-6 times to control the disease which resulted in increased cost of cultivation and sometimes fungicides spray is of no use. Hence, late blight disease resistant hybrid Arka Abhed was tested against Arka Samrat and private hybrid in KVK operational area. Data on disease incidence was collected at 30, 60, 90 DAP in all the hybrids. The data revealed that Arka abhed recorded significantly lower incidence of late blight than other hybrids during all crop growth stages. It recorded 2.6% late blight incidence whereas Arka Samrat and private hybrid recorded 46.6% and 50% of disease incidence. Numb

Keywords

Tomato, late blight disease, resistant hybrid, Arka Abhed.

Conclusion

Overall, Arka Abhed performed very well in farmers fields with good fruit quality, longer crop duration, high yield and maintained good late blight resistance under field conditions which are highly conducive to late blight development. If the problem of over size is rectified, the hybrid has very good scope to reach farming community.
