Biophysical characters of tomato varieties in relation to resistance against tomato fruit borer, Helicoverpa armigera (Hubner)

Priyanka Thakur, RS Rana and Arvind Kumar

The study on relation of morphological characters to the fruit infestation of H. armigera was conducted on the farm, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan, HP. On the selected eight tomato varieties morphological characters of tomato plant as well as fruits were measured and compared. The percent fruit damage varied from 15.57 to 45.30 per cent recording the highest fruit infestation in ‘Red Gold’ and lowest in ‘Solan Lalima’. Tomato fruit borer infestation was significantly positively correlated with fruit diameter (r= 0.526), leaf area (r= 0.686) and leaf hairs (r= 0.497); while negative correlation was found with fruit length (r= -0.694), fruit shape (r= -0.772) and pericarp thickness (r= -0.453). The correlation analysis of fruit infestation with plant height, stem diameter, fruit infestation, fruit weight and fruit yield/plant was found to be non-significant.
