ABSTRACT The incidence of plants diseases has been one of the major limiting factors in achieving the production potential of the crops. Only red rot is causing economic losses to the crop and major incidence in sugarcane growing areas of India. An experiment was conducted at GSSBRI, Seorahi, Kushinagar with collaboration of breeding programmed for autumn planted four crop sessions since 2015-17 to 2018-20. Freshly highly sporulating 7–9 days old culture of Colletotrichum falcatum Went; was made from petriplates were incubated at 30±1°C temperature on BOD incubator. Spore suspension at a concentration of 106per ml was added for inoculation of each genotype by plug method. In present study of disease reaction on 5036 genotypes was evaluated against red rot disease. After 60 days of the inoculated these genotypes was split open longitudinally along with the point of inoculation. Observations were recorded on the basis of the international scale (0–9) for assessing the screening as condition of top, lesion width, nodal transgression and white spots. In our study for 5036 genotypes were evaluated against red rot disease, out of which 1856 genotypes were found as moderately resistant (MR), 1078 genotypes were rated as moderately susceptible (MS), 977 genotypes were rated as susceptible (S), and 1042 genotypes were found highly susceptible (HS) with checks were found similar and dissimilar reaction, while rest genotypes were found water shoot phases. Consequently, these moderately resistant (MR) 1856 genotypes could be utilized in further studies in the breeding programme for developing red rot resistant clones for next generation. |
