Physio-morpho and biochemical basis of resistance in groundnut germplasm against thrips

Author(s):

Abstract:
The screening of groundnut germplasms during Rabi, 2021–22, at the College of Agriculture, Raipur, farm revealed that NRCG - 134, NRCG - 8457, NRCG - 10348, NRCG – 10406 and NRCG – 10328 were the relatively resistant germplasms for thrips. The resistance in these germplasms was conferred due to higher leaf thickness (mm), trichome density per mm2, and high chlorophyll content. The correlation studies also revealed that there was a significant negative correlation between biophysical parameters [leaf thickness (r = -0.910), trichome density (r = -0.945), and chlorophyll content (r = -0.588] and percent leaf damage by thrips. Except for phenols (r = -907), which exhibited a significant negative correlation with thrips percentage damage, other biochemical measures [total sugars (r = 0.942), reducing sugars (r = 0.914), non-reducing sugars (r = 0.709), and amino acids (r = 0.975)] showed a significant positive correlation with the percentage of leaf damage caused by thrips.
