SCREENING OF FINAL SUGARCANE GENOTYPES (Saccharum officinarum L.) FOR RED ROT Colletotricum falcatum Went DISEASE RESISTANCE

Abstract

Thirty sugarcane (Saccharum officinarum) genotypes were screened two consecutive years 2007-2008 against red rot (Colletotricum falcatum) disease by artificial inoculation using “syringe methodâ€. The genotypes were graded as various levels of susceptibility and resistance using standard disease index. Two genotypes S98CSSG-668 and S98CSSG676 appeared resistance, one moderately resistance, two moderately susceptible and twenty five were susceptible. These genotypes (S98CSSG-668 and S98CSSG676) may be utilized as one of the sources of resistance on the breeding programme of sugarcane to red rot disease.
