Mungbean Yellow Mosaic Infection and Biochemical Variability inBlackgram Genotypes

摘要

Mungbean yellow mosaic disease varied from 3.73 (DKU-87) to 96.15%(LBG-623) in 16 blackgram [Vigna mungo (L.) Hepper] genotypes tested. Of the 16 genotypes nine genotypes were categorised as resistant, one as moderately resistant, four genotypes as susceptible and two as highly susceptible genotypes. Significant variation was observed among the genotypes tested with respect to the amount of total phenols, total proteins, total chlorophyll, peroxidases and phenylalanine ammonia lyase activity. High amount of biochemical substances wererecorded in resistant genotypes than other genotypes.
