Abstract:
French bean (Phaseolus vulgaris L.) belongs to the family fabaceae grown for its green tender pods as well as dry beans. Cultivation of this crop was hindered due to various biotic stresses. Among them rust caused by Uromyces phaseoli leads to the yield loss to the tune of 18 to 78%. Several fungicides like chlorothalonil used for the control of rust disease. However use of resistant varieties is the ideal way for the control of rust disease. Principal component analysis (PCA) was used to reduce the size of the data set containing the disease assessment characteristics. The present study aimed to identify the individual components responsible rust infection in french bean.
