Abstract

This study was carried out to screen Phaseolus vulgaris L. germplasm accessions for anthracnose resistance genes to the fungus Colletotrichum lindemuthianum. (Sacc. and Magn.) Scrib. This fungus is made up of many pathogenic races which poses a challenge in developing resistant plant varieties; however, screening for and selection of resistant plant sources plays an important role in developing resistant plant lines. This screening work involved examining 69 accessions consisting of two resistant lines (D-line, L-line) and two susceptible varieties (Kanchana and Jwala). Fourteen SCAR primers specific to anthracnose disease resistance in the French bean were used. Of these 14 SCAR primers, 5 of them, SAS13, SF10, SC08, SZ04 and SBB14, produced amplification with good monomorphic bands.
