Screening of Tomato Varieties/Hybrids against Aphid (Aphis gossypii Glover) under Field Condition

An investigation on screening of tomato varieties/hybrids against aphid (Aphis gossypii Glover) under field condition were conducted at Entomological Research Field, College of Agriculture, Gwalior, Madhya Pradesh, India. Eighteen varieties/hybrids were sown and different levels of aphid incidence were observed over two successive years (2022–23 and 2023–24). The result of present investigation indicated that none of the varieties/hybrids were completely free from aphid incidence. Among the eighteen varieties/hybrids, two were categorized as less susceptible, twelve as moderately susceptible and four as highly susceptible against aphid. The variety/hybrid Arka Vishal had the lowest aphid population followed by Kashi Adarsh. The highest aphid population found in variety/hybrid Vaishali which was statistically at par with Swati 444.
