ASSOCIATION ANALYSIS AND EVALUATION OF SOURCES FOR RESISTANCE TO PHYLLODY AND FOLIAR DISEASES IN SESAME (SESAMUM INDICUM L.)Divyak, Kiran Babut, Shobha Ranit and Padmajad
In the present investigation, a set of advanced mutant and breeding lines (133) including checks from different geographical regions were evaluated against phyllody and Alternaria leaf spot during kharif, 2017 and against powdery mildew during summer, 2018 under natural epiphytotic field conditions. Among the entries, two genotypes (LW-2 and SDSN-15-98) were found to be promising for phyllody during kharif, 2017 whereas, the genotype LW-2 was also found to be moderately resistant against powdery mildew during summer, 2018. None of the genotypes were promising against Alternaria leaf spot. The association of agronomic traits namely plant height, thousand seed weight, number of branches/plant, number of capsules/ plant was correlated negatively significant with diseases. The genotype LW-2 identified promising against phyllody and powdery mildew will be useful in hybridization programme as donor parent for development of multiple disease resistant sesame varieties.
