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

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