Some of the areas where biotechnology has played a significant role are detailed below. 1. Production of pathogen – free plants. Plants traditionally being vegetatively propogated are systemically infected with viruses & other pathogens which greatly reduce yield & also Q uality of the marketed commodity. Virus diseases like potato leaf roll virus (PLRV)...
