Abstract

Screening against anthracnose (Colletotrichum lindemuthianum) was conducted using 20 genotypes of French bean (Phaseolus vulgaris) for identifying the resistant genotypes. Three genotypes viz., Rajma Gold, ML-D and ML-F were found moderately resistant, whereas ten and seven genotypes were categorized as moderately susceptible and susceptible, respectively. None of the genotypes was found highly resistant or highly susceptible. Estimation of yield loss due to anthracnose under protected and non-protected conditions using a susceptible variety Manipuri local -J revealed that reduction in pod wt. varied from 9.1 to 11.2%, pod length from 4.3 to 6.6%, breadth 4.5 to 8.8%, and thickness 16.6 to 30.5% according to disease severity rating. This study provided conclusive evidence that pod length, breadth and thickness are also affected according to various infection categories.
