Abstract:

This experiment was conducted to understand the biochemical and anatomical differences in the highly resistant and susceptible recombinant inbred lines (RILs) of cotton for sucking pests. These factors are considered to play a major role in the resistance mechanism against insects. The results in present study was revealed that resistant RILs contain high phenol and gossypol but low in reducing sugar compared to susceptible RILs. Anatomically, resistant RILs had less thickness of leaf lamina, and less distance between lower and upper epidermis of midrib but possessed more number of cortical and palisade cells indicates the compactness of the tissue in leaves and midrib as compared to susceptible RILs. The distance between lower epidermis and phloem was found to be more in resistant RILs compared to susceptible RILs.


Keywords: Cotton, Gossypol, Reducing sugar, Phenol, Anatomy, RILs.
