Biochemical traits associated with resistance to Whitefly, Bemisia tabaci (Gennadius) in green gram

Abstract

Results revealed that maximum population was reported in ML 5 (9.12 whitefly cage-) followed by SM 48(8.45 whitefly cage-1-) and the minimum population was recorded in PM-5 (3.02 whitefly cage-) closely followedby IPM 306-1 (3.51 whitefly cage-). However, the population local check cultivar, HUM-12 was 6.45 whiteflycage-. The biochemical factors like protein, total sugar, phenol and total chlorophyll were estimated in 20promising varieties/ genotypes of green gram. The highest protein content was found in genotype ML 5 (12.77mg g-) and minimum in genotype PM-5 (7.45 mg g-). Maximum total sugar content was reported from genotypeML 5 (07.86 mg g-) and minimum total sugar content recorded in PM-5 (03.34 mg g-). The phenol content ingenotype PM-5 (4.23 mg g-) was significantly higher than others whereas, the minimum phenol content wasreported in ML5 (2.43 mg g-). The higher amount of total chlorophyll content was found in genotype PM-5(3.92 mg g-) and lower in genotype ML 5 (1.30 mg g-). The significant and positive correlation was witnessedbetween B. tabaci population and protein (r=0.976**) and total sugar content (r=0.981**), while, the significantand negative correlation was found between phenol (r = -981**) and total chlorophyll content (r = -978**) © 2021, Journal of Entomological Research.All Rights Reserved.
