Abstract

Four methods were used to get best production of apothecia and maximum number of mature saucer shaped, brownish yellow apothecia. Comparison and assessment of the performance of different inoculation methods, the proposed inoculum placement proved to be the best method of inoculation showed 86.7% infection followed by tooth pick (55.6%) and ascospores inoculation method (53.3%). Soil inoculation method appeared to be less effective as compared to other methods. Out of tested genotypes, five genotypes viz., RL 1359, PHR 33, RK 8502, RK 8201 and PAB 9511 were found resistant and two RK 9902 and CSR 1296 showed moderately resistant.
