Abstract:
Correlation studies were conducted between different physio-morphological and biochemical parameters with per cent leaf damage due to Spodoptera litura on soyabean under field conditions. The correlation studies revealed that the per cent leaf damage had significant and positive correlation with different parameters like leaf succulency (r = 0.841**), chlorophyll content (r = 0.580**) and reducing sugars (r = 0.850**). Whereas significant and negative correlation was found between per cent leaf damage and trichome density (r = - 0.905**), phenol content (r = -0.866**). For plant height (r = -0.168), leaf shape there was non-significant correlation with per cent leaf damage.
