The first part was conducted at seedling stage at 2 and 5 DAG consisting of seven genotypes out of which five (J-2480, J-2511, J- 2290, J-2405 and J-2340) were resistant and two (7042S and J-2372) were susceptible to downy mildew. These genotypes were analysed for isozymes like POX, EST, PPO and SOD at both stagesenBiochemistryStudyThesis
