Abstract: Nine cotton genotypes viz. HD418, HD432, HD503, H1439, H1463, H1454, H1464, H1465 and H1098 were evaluated under field conditions to compare their resistance levels to sucking pest attack. In the present study, ascorbate and β-carotene content of cotton genotypes infected by sucking pests were estimated in the leaves (2nd & 6th) at 50, 60 and 68 days after sowing (DAS). The ascorbate and β carotene content before infection was maximum in 2nd & 6th leaves of G. arboreum genotypes followed by G. hirsutum resistant genotypes and minimum in G. hirsutum susceptible genotypes. After infection the ascorbate and β carotene content increased in all the genotypes in both the leaves. The maximum increase in content of ascorbate and β-carotene were observed in 6th leaves after pests’ infection and more increase was in resistant genotypes than susceptible genotypes.
