Biochemical Constituent of Brassica Juncea Genotypes In Relation To Mustard Aphid (Lipaphis Erysimi Kalt.) Infestation

Author(s): Manju Yadav and JS Rana
Abstract: Selected thirty genotypes of Brassica juncea were evaluated for mustard aphid infestation on the basis of average number of aphids per plant and their bio-chemical analysis was carried out at flowering stage. Higher sinigrin content was obtained in genotype RH 7846 (73.49 µ mole/g DM) and lower in Kranti (31.02 µ mole/g DM). A highly significant and negative correlation was observed between sinigrin content and aphid infestation. Phenol content varied from 1.4 % (Varuna) to 2.44 % (RH 7846). The correlation coefficient between phenol content and aphid infestation index was negative and significant. The amount of waxes in leaves of Brassica juncea genotypes varied from 2.62 % (RB 50) to 5.22 % (RH 8701 & RLM 198). The correlation coefficient between waxes content in leaves of plant and mustard aphid infestation was negative and non-significant.
